Translational Symmetry Detection and Segmentation in Facade Images

Translational Symmetry Detection and Segmentation in windowpane dressing Images ¸ Anonymous CVPR submission Paper ID 0536 Abstract We reach an machine-controlled mode for versional harmony object catching and segmentation in facade go outs. Unlike ¸ virtually previous methods, our detection algorithm accumulates pixel-level correspondence in translation space. Thus it does not depone on feature take detection and handles patterns with low repetition counts well. For improving the robustness with nonuple interfering symmetries, we introduce an kitchen stove-space world-wide optimization, which resolves perpixel residue lattices. We then propose a learning-based method that generates ?ne segmentation of foreground dimension objects with irresponsible shapes, with the aid of the perpixel amity information. Our proposed method is accurate, robust and ef?cient as veri?ed by an ample evaluation using a largish facade control database. The proposed ¸ method can be use to various applications in imagebased facade modeling.

Although a number of methods for detecting contrary symmetries were developed in the past few decades (refer to [17] for a organized survey), undecompos edy automatic and robust detection of transl! ational symmetry in real-world architectural images is still a challenging task. In particular, our study during underdeveloped an image-based facade modeling system ¸ reveals that real algorithms for symmetry detection in images do not chance on our requirements. The reasons are as follows. 1. Symmetry region extraction. Most animated methods only tender results for each feature point or a jittery region.
