  abstract =   "Building facades typically consist of multiple similar tiles
               which are arranged quite strictly in grid-like structures.
               The proposed method takes advantage of translational
               symmetries and is able to analyze and segment facades into
               tiles assuming that there are horizontal and vertical
               repetitions of similar tiles. In order to solve this quite
               complex computer vision task efficiently a Monte Carlo
               approach is presented which samples only selected image
               features. This method, which is meant to be a preprocessing
               step for more sophisticated tile segmentation and window
               identification in urban reconstruction tasks, is able to
               robustly identify orthogonal repetitive patterns on
               rectified facade images even if they are partially occluded,
               shadowed, blurry or otherwise damaged. Additionally, the
               algorithm is very running time efficient because neither
               quality of results nor the computational complexity are
               significantly depending on the image size.",
