There exist various approaches to this issue, which span several research areas including computer graphics, image processing, color vision, physiological aspects, etc. These approaches assume a thorough knowledge of both the objective and subjective attributes of an image. However, no comprehensive overview and analysis of such attributes has been published so far.\n\nIn this contribution, we present an overview about the effects of basic image attributes in HDR tone mapping. Furthermore, we propose a scheme of relationships between these attributes, leading to the definition of an overall image quality measure. We present results of subjective psychophysical experiments that we have performed to prove the proposed relationship scheme. Moreover, we also present an evaluation of existing tone mapping methods (operators) with regard to these attributes. Finally, the execution of with-reference and without a real reference perceptual experiments gave us the opportunity to relate the obtained subjective results.\n\nOur effort is not just useful to get into the tone mapping field or when implementing a tone mapping method, but it also sets the stage for well-founded quality comparisons between tone mapping methods. By providing good definitions of the different attributes, user-driven or fully automatic comparisons are made possible.\n", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1600, "image_height": 1200, "name": "CADIK-2008-EHD-.bmp", "type": "image/x-ms-bmp", "size": 5760054, "path": "Publication:CADIK-2008-EHD", "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CADIK-2008-EHD/CADIK-2008-EHD-.bmp", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2008/CADIK-2008-EHD/CADIK-2008-EHD-:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 635, 193, 177, 191 ], "issn": "0097-8493", "journal": "Computers & Graphics", "number": "3", "pages_from": "330", "pages_to": "349", "volume": "32", "research_areas": [ "Rendering" ], "keywords": [ "high dynamic range", "tone mapping operators", "tone mapping evaluation", "image attributes" ], "weblinks": [], "files": [ { "description": null, "filetitle": "", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 1600, "image_height": 1200, "name": "CADIK-2008-EHD-.bmp", "type": "image/x-ms-bmp", "size": 5760054, "path": "Publication:CADIK-2008-EHD", "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CADIK-2008-EHD/CADIK-2008-EHD-.bmp", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2008/CADIK-2008-EHD/CADIK-2008-EHD-:thumb{{size}}.png" }, { "description": null, "filetitle": "Preprint", "main_file": true, "use_in_gallery": false, "access": "public", "name": "CADIK-2008-EHD-Preprint.pdf", "type": "application/pdf", "size": 2159163, "path": "Publication:CADIK-2008-EHD", "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CADIK-2008-EHD/CADIK-2008-EHD-Preprint.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2008/CADIK-2008-EHD/CADIK-2008-EHD-Preprint:thumb{{size}}.png" } ], "projects_workgroups": [ "Treelumination" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2008/CADIK-2008-EHD/", "__class": "Publication" }, { "id": "Habel_08_SSH", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Efficient Spherical Harmonics Lighting with the Preetham Skylight Model", "date": "2008-04", "abstract": "We present a fast and compact representation of a skylight model for spherical harmonics lighting, especially for outdoor scenes.

We present an efficient GPU ray casting algorithm which provides correct parallax, self-occlusion, and silhouettes, at the cost of longer rendering times. The new formulation also allows modeling shells with smooth curvatures using Coons patches within the prisms.

The rendering performance is output sensitive, i.e., it scales with\nthe number of pixels rather than the complexity of the landscape. Given a height field of a terrain and a topographic map or similar data as input, the vegetation cover is extracted and stored on top of the height field in a preprocess, enhancing the terrain with forest canopies or other mesostructure. In addition, enhanced illumination models like shadowing and ambient occlusion can be calculated at runtime with reasonable computational cost, which greatly enhances the scene realism. Finally, including the presented technique into existing rendering systems is relatively simple, mainly consisting of data preparation and pixel shader programming.", "authors_et_al": false, "substitute": null, "main_image": { "description": null, "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 640, "image_height": 480, "name": "Mantler-06-landscape-image.png", "type": "image/png", "size": 568584, "path": "Publication:Mantler-06-landscape", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mantler-06-landscape/Mantler-06-landscape-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mantler-06-landscape/Mantler-06-landscape-image:thumb{{size}}.png" }, "sync_repositum_override": null, "repositum_presentation_id": null, "authors": [ 407, 356 ], "booktitle": "Proceedings of Graphite 2006", "date_from": "2006-11-29", "date_to": "2006-12-02", "lecturer": [ 407, 356 ], "research_areas": [ "Rendering" ], "keywords": [ "real-time rendering", "gpu ray casting" ], "weblinks": [], "files": [ { "description": null, "filetitle": "image", "main_file": false, "use_in_gallery": true, "access": "public", "image_width": 640, "image_height": 480, "name": "Mantler-06-landscape-image.png", "type": "image/png", "size": 568584, "path": "Publication:Mantler-06-landscape", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mantler-06-landscape/Mantler-06-landscape-image.png", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mantler-06-landscape/Mantler-06-landscape-image:thumb{{size}}.png" }, { "description": null, "filetitle": "paper", "main_file": true, "use_in_gallery": false, "access": "public", "name": "Mantler-06-landscape-paper.pdf", "type": "application/pdf", "size": 23601326, "path": "Publication:Mantler-06-landscape", "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mantler-06-landscape/Mantler-06-landscape-paper.pdf", "thumb_image_sizes": [ 16, 64, 100, 175, 300, 600 ], "thumb_url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mantler-06-landscape/Mantler-06-landscape-paper:thumb{{size}}.png" } ], "projects_workgroups": [ "Treelumination" ], "url": "https://www.cg.tuwien.ac.at/research/publications/2006/Mantler-06-landscape/", "__class": "Publication" }, { "id": "CADIK-2006-IAQ", "type_id": "inproceedings", "tu_id": null, "repositum_id": null, "title": "Image Attributes and Quality for Evaluation of Tone Mapping Operators", "date": "2006-10", "abstract": "The problem of reproducing high dynamic range images\non devices with restricted dynamic range has gained a lot\nof interest in the computer graphics community.

Furthermore,\nwe propose a scheme of relationships between these\nattributes, leading to the definition of an overall image quality\nmeasure. We present results of subjective psychophysical\ntests that we have performed to prove the proposed relationship\nscheme. We also present the evaluation of existing tone\nmapping methods with regard to these attributes.\nOur effort is not just useful to get into the tone mapping\nfield or when implementing a tone mapping operator, but\nit also sets the stage for well-founded quality comparisons\nbetween tone mapping operators.
