One of the possible approaches is to use GeoRadar to examine wall structures by analyzing the data obtained from the scans. However, so far, the obtained data have to be assessed manually, relying on the experience of the user in interpreting GPR radargrams. We propose a data-driven approach to evaluate the material composition of a wall from its GPR radargrams. In order to generate training data, we use gprMax to model the scanning process. Using simulation data, we use a convolutional neural network to predict the thicknesses and dielectric properties of walls per layer.

This is typically a lengthy process that involves a trained artist with specialized knowledge. In this work, we present a technique that aims to empower novice and intermediate-level users to synthesize high-quality photorealistic materials by only requiring basic image processing knowledge. In the proposed workflow, the user starts with an input image and applies a few intuitive transforms (e.g., colorization, image inpainting) within a 2D image editor of their choice, and in the next step, our technique produces a photorealistic result that approximates this target image. Our method combines the advantages of a neural network-augmented optimizer and an encoder neural network to produce high-quality output results within 30 seconds. We also demonstrate that it is resilient against poorly-edited target images and propose a simple extension to predict image sequences with a strict time budget of 1-2 seconds per image.\n\nVideo:

Resulting 3D models are based on few 2D microscopy scans and the latest knowledge about the biological entity represented as a set of geometric relationships. Our new technique is based on statistical and rule-based modeling approaches that are rapid to author, fast to construct, and easy to revise. From a few 2D microscopy scans, we learn statistical properties of various structural aspects, such as the outer membrane shape, spatial properties and distribution characteristics of the macromolecular elements on the membrane. This information is utilized in 3D model construction. Once all imaging evidence is incorporated in the model, additional information can be incorporated by interactively defining rules that spatially characterize the rest of the biological entity, such as mutual interactions among macromolecules, their distances and orientations to other structures. These rules are defined through an intuitive 3D interactive visualization and modeling feedback loop. We demonstrate the utility of our approach on a use case of the modeling procedure of the SARS-CoV-2 virus particle ultrastructure.

However, little work exists on finding similar points in dissimilar shapes. In this paper, we present the results of a study where users were given two dissimilar two-dimensional shapes and asked to map a given point in the first shape to the point in the second shape they consider most similar. We find that user mappings in this study correlate strongly with simple geometric relationships between points and shapes. To predict the probability distribution of user mappings between any pair of simple two-dimensional shapes, two distinct statistical models are defined using these relationships. We perform a thorough validation of the accuracy of these predictions and compare our models qualitatively and quantitatively to well-known shape-matching methods.

Starting from an abstraction of the partially observed layout as a set of shapes, we can propose one or multiple possible completed layouts. Structure completion with large missing parts is an ill-posed problem. Therefore, we combine two sources of information to derive our solution: the observed shapes and a database of complete layouts. The problem is also very difficult, because shape positions and attributes have to be estimated jointly. Our proposed solution is to break the problem into two components: a statistical model to evaluate layouts and a planning algorithm to generate candidate layouts.

Our approach is based on the minimization of an energy function that combines multiple goals: positioning of the lenses as close as possible to the corresponding region shown in an overview map, keeping the number of lenses low, and an efficient numbering of the lenses.\nThe second contribution is a route-aware simplification of the graph of streets used for traveling between the points of interest (POIs). This is done by reducing the graph consisting of all shortest paths through the minimization of an energy function. The output is a subset of street segments that enable traveling between all the POIs without considerable detours, while at the same time guaranteeing a clutter-free visualization.\n\nVideo:

relationship functions. These functions quantify the geometric relationship of a point to a polygon, such as the distance to the boundary or the direction to the closest corner vertex. The level sets of the relationship functions describe points with the same relationship to a polygon. For a given query point we ?rst determine a set of relationships to local features, construct all level sets for these relationships and accumulate them. The maxima of the resulting distribution are points with similar geometric relationships. We show extensions to handle mirror symmetries, and discuss the use of relationship functions as local coordinate systems. Our method can be applied for example to interactive ?oor-plan editing, and is especially useful for large layouts, where individual edits would be cumbersome. We demonstrate populating 2D layouts with tens to hundreds of objects by propagating relatively few edit operations.", "authors_et_al": false, "substitute": null, "main_image": { "description": "representative image", "filetitle": "representative_image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1520, "image_height": 1336, "name": "Guerrero-2014-GRF-representative_image.jpg", "type": "image/jpeg", "size": 517288, "path": "Publication:Guerrero-2014-GRF", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-representative_image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-representative_image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 627, 356, 193, 194 ], "date_from": "2014-08-10", "date_to": "2014-08-14", "doi": "10.1145/2591010", "event": "ACM SIGGRAPH 2014", "issn": "0730-0301", "journal": "ACM Transactions on Graphics", "lecturer": [ 627 ], "location": "Vancouver, Canada", "number": "2", "pages_from": "15:1", "pages_to": "15:15", "volume": "33", "research_areas": [ "Modeling" ], "keywords": [ "Shape Modeling", "Floor Plans", "Edit Propagation", "Geometric Relationship Functions" ], "weblinks": [ { "href": "http://doi.acm.org/10.1145/2591010", "caption": null, "description": null, "main_file": 0 } ], "files": [ { "description": "individual steps of the apartment building example", "filetitle": "apartment_editing", "main_file": false, "use_in_gallery": false, "access": "public", "name": "Guerrero-2014-GRF-apartment_editing.pdf", "type": "application/pdf", "size": 12639838, "path": "Publication:Guerrero-2014-GRF", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-apartment_editing.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-apartment_editing:thumb{{size}}.png" }, { "description": "individual steps of the palace garden example", "filetitle": "garden_editing", "main_file": false, "use_in_gallery": false, "access": "public", "name": "Guerrero-2014-GRF-garden_editing.pdf", "type": "application/pdf", "size": 74317887, "path": "Publication:Guerrero-2014-GRF", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-garden_editing.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-garden_editing:thumb{{size}}.png" }, { "description": "pre-print version of the paper", "filetitle": "paper", "main_file": true, "use_in_gallery": false, "access": "public", "name": "Guerrero-2014-GRF-paper.pdf", "type": "application/pdf", "size": 16383816, "path": "Publication:Guerrero-2014-GRF", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-paper.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-paper:thumb{{size}}.png" }, { "description": "representative image", "filetitle": "representative_image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1520, "image_height": 1336, "name": "Guerrero-2014-GRF-representative_image.jpg", "type": "image/jpeg", "size": 517288, "path": "Publication:Guerrero-2014-GRF", "url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-representative_image.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/Guerrero-2014-GRF-representative_image:thumb{{size}}.png" } ], "projects_workgroups": [ "rend" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2014/Guerrero-2014-GRF/", "__class": "Publication" }, { "id": "musialski-2013-surcgf", "type_id": "journalpaper_notalk", "tu_id": null, "repositum_id": null, "title": "A Survey of Urban Reconstruction", "date": "2013-09", "abstract": "This paper provides a comprehensive overview of urban reconstruction.

We show the application of the algorithm on typical photographs and compare the results to other color replacement methods.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "teaser", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 2061, "image_height": 925, "name": "musialski_2012_fice-teaser.jpg", "type": "image/jpeg", "size": 347836, "path": "Publication:musialski_2012_fice", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-teaser.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-teaser:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 844, 1032, 986, 811, 194 ], "journal": "The Visual Computer", "number": "11", "pages_from": "1173", "pages_to": "1186", "volume": "29", "research_areas": [], "keywords": [ "interactive image editing", "color manipulation", "image processing", "recoloring", "computational photography" ], "weblinks": [ { "href": "http://www.springerlink.com/content/q1272h717v1q3262/", "caption": null, "description": null, "main_file": 0 } ], "files": [ { "description": "MATLAB code", "filetitle": "code", "main_file": false, "use_in_gallery": false, "access": "public", "name": "musialski_2012_fice-code.rar", "type": "application/x-rar", "size": 12828879, "path": "Publication:musialski_2012_fice", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-code.rar", "thumb_image_sizes": [] }, { "description": "comparison to other methods", "filetitle": "comparison", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 1157, "image_height": 1389, "name": "musialski_2012_fice-comparison.jpg", "type": "image/jpeg", "size": 317713, "path": "Publication:musialski_2012_fice", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-comparison.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-comparison:thumb{{size}}.png" }, { "description": "paper draft [8MB]", "filetitle": "draft", "main_file": true, "use_in_gallery": false, "access": "public", "name": "musialski_2012_fice-draft.pdf", "type": "application/pdf", "size": 7897867, "path": "Publication:musialski_2012_fice", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-draft.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-draft:thumb{{size}}.png" }, { "description": "results of the proposed method", "filetitle": "results", "main_file": false, "use_in_gallery": false, "access": "public", "image_width": 3187, "image_height": 2928, "name": "musialski_2012_fice-results.jpg", "type": "image/jpeg", "size": 1035913, "path": "Publication:musialski_2012_fice", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-results.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-results:thumb{{size}}.png" }, { "description": "", "filetitle": "teaser", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 2061, "image_height": 925, "name": "musialski_2012_fice-teaser.jpg", "type": "image/jpeg", "size": 347836, "path": "Publication:musialski_2012_fice", "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-teaser.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/musialski_2012_fice-teaser:thumb{{size}}.png" } ], "projects_workgroups": [ "Photo-Guide" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2012/musialski_2012_fice/", "__class": "Publication" }, { "id": "musialski-2012-sur", "type_id": "otherreviewed", "tu_id": null, "repositum_id": null, "title": "A Survey of Urban Reconstruction", "date": "2012-05", "abstract": "This paper provides a comprehensive overview of urban reconstruction.

First, we propose a definition for the tensor trace norm, that generalizes the established definition of the matrix trace norm. Second, similar to matrix completion, the tensor completion is formulated as a convex optimization problem. We developed three algorithms: SiLRTC, FaLRTC, and HaLRTC. The SiLRTC algorithm is simple to implement and employs a relaxation technique to separate the dependant relationships and uses the block coordinate descent (BCD) method to achieve a globally optimal solution; The FaLRTC algorithm utilizes a smoothing scheme to transform the original nonsmooth problem into a smooth one; The HaLRTC algorithm applies the alternating direction method of multipliers (ADMM) to our problem.

These colors are diffused over the image plane, resulting in smooth color regions\nas well as sharp boundaries. In this paper, we introduce a new automatic diffusion curve coloring algorithm. We\nstart by defining a geometric heuristic for the maximum density of color control points along the image curves.\nFollowing this, we present a new algorithm to set the colors of these points so that the resulting diffused image is as close as possible to a source image in a least squares sense. We compare our coloring solution to the existing one which fails for textured regions, small features, and inaccurately placed curves. The second contribution of the paper is to extend the diffusion curve representation to include texture details based on Gabor noise. Like the curves themselves, the defined texture is resolution independent, and represented compactly. We define methods to automatically make an initial guess for the noise texure, and we provide intuitive manual controls to edit the parameters of the Gabor noise. Finally, we show that the diffusion curve representation itself extends to storing any number of attributes in an image, and we demonstrate this functionality with image stippling an

modeling of city layouts that combine the power of procedural modeling with the flexibility of manual modeling. Procedural modeling enables us to quickly generate large city layouts, while manual modeling allows us to hand-craft every aspect of a city. We introduce transformation and merging operators for both topology preserving and topology changing transformations based on graph cuts. In combination with a layering system, this allows intuitive manipulation of urban layouts using operations such as drag and drop, translation, rotation etc. In contrast to previous work, these operations always generate valid, i.e., intersection-free layouts. Furthermore, we introduce anchored assignments to make sure that modifications are persistent even if the whole urban layout is regenerated.\n", "authors_et_al": false, "substitute": null,

Our solution can split the derivation of the L-system as well as the interpretation and geometry generation into thousands of threads running in parallel. We introduce a highly parallel algorithm for L-system evaluation that works on arbitrary L-systems, including parametric productions, context sensitive productions, stochastic production selection, and productions with side effects. This algorithm is further extended to allow evaluation of multiple independent L-systems in parallel. In contrast to previous work, we directly interpret the productions defined in plain-text, without requiring any compilation or transformation step (e.g., into shaders). Our algorithm is efficient in the sense that it requires no explicit inter-thread communication or atomic operations, and is thus completely lock free.", "authors_et_al": false, "substitute": null, "main_image": { "description": "", "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 600, "image_height": 400, "name": "LIPP-2010-PGMS-.jpg", "type": "image/jpeg", "size": 113897, "path": "Publication:LIPP-2010-PGMS", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/LIPP-2010-PGMS/LIPP-2010-PGMS-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/LIPP-2010-PGMS/LIPP-2010-PGMS-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 680, 194, 193 ], "issn": "0097-8493", "journal": "Computers & Graphics", "number": "5", "pages_from": "585", "pages_to": "593", "volume": "34", "research_areas": [], "keywords": [], "weblinks": [], "files": [ { "description": "", "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 600, "image_height": 400, "name": "LIPP-2010-PGMS-.jpg", "type": "image/jpeg", "size": 113897, "path": "Publication:LIPP-2010-PGMS", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/LIPP-2010-PGMS/LIPP-2010-PGMS-.jpg", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/LIPP-2010-PGMS/LIPP-2010-PGMS-:thumb{{size}}.png" }, { "description": "", "filetitle": "preprint", "main_file": true, "use_in_gallery": false, "access": "public", "name": "LIPP-2010-PGMS-preprint.pdf", "type": "application/pdf", "size": 2697005, "path": "Publication:LIPP-2010-PGMS", "url": "https://www.cg.tuwien.ac.at/research/publications/2010/LIPP-2010-PGMS/LIPP-2010-PGMS-preprint.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2010/LIPP-2010-PGMS/LIPP-2010-PGMS-preprint:thumb{{size}}.png" } ], "projects_workgroups": [ "GAMEWORLD" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2010/LIPP-2010-PGMS/", "__class": "Publication" }, { "id": "musialski-2010-tof", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Tiling of Ortho-Rectified Façade Images", "date": "2010-05", "abstract": "Typical building facades consist of regular structures such as windows arranged in a predominantly grid-like manner.

A DCI consist of curves with colors defined on either side. By diffusing these colors over the image, the final result includes sharp boundaries along\nthe curves with smoothly shaded regions between them. This paper extends the application of diffusion curves to render high quality surface details on 3D objects. The first extension is a view dependent warping technique that dynamically reallocates texture space\nso that object parts that appear large on screen get more texture for increased detail.

The simplicity of our basic algorithm naturally extends to the sampling of other surface types,\nincluding spheres, NURBS, subdivision surfaces, and implicits. We further extend the method to handle variable\ndensity points, and the placement of arbitrary ellipsoids without overlap.

The main\r\ngoal of our system is to generate a printable version of a route map that shows the overview and detail views of the route within a single, consistent visual frame. Our proposed visualization provides a more intuitive spatial context than a simple list of turns. We present a novel multi-focus technique to achieve this goal, where the foci are defined by points-of-interest (POI) along the route. A detail lens that encapsulates the POI at a finer geospatial scale is created for each focus. The lenses are laid out on the map to avoid occlusion with the route and each other, and to optimally utilize the free space around the route.

The algorithm is fast to calculate and therefore also useful for scenes of moderate complexity and walkthroughs with over 20 frames per second. Occlusion is calculated dynamically and does not rely on any visibility precalculation or occluder preselection. Speed-ups of one order of magnitude can be obtained.", "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 194, 202 ], "date_from": "1999-09-07", "date_to": "1999-09-11", "event": "EUROGRAPHICS'99", "issn": "1067-7055", "journal": "Computer Graphics Forum", "location": "Milan, Italy", "number": "3", "pages_from": "51", "pages_to": "60", "volume": "18", "research_areas": [], "keywords": [], "weblinks": [], "files": [], "projects_workgroups": [], "url": "https://www.cg.tuwien.ac.at/research/publications/1999/Wonka-1999-Occ/", "__class": "Publication" }, { "id": "Wonka-1998-Ray", "type_id": "misc", "tu_id": null, "repositum_id": null, "title": "Raytracing of nonlinear fractals", "date": "1998", "abstract": null, "authors_et_al": false, "substitute": null, "main_image": null, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 194, 249 ], "note": "WSCG Plzen 1998 Proceedings, pp. 424-431, 1998.", "research_areas": [], "keywords": [], "weblinks": [], "files": [], "projects_workgroups": [], "url": "https://www.cg.tuwien.ac.at/research/publications/1998/Wonka-1998-Ray/", "__class": "Publication" } ]
