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 personate an machine-controlled mode for displacement reactional harmony object surprise and segmentation in facade go outs. Unlike ¸ roughly previous methods, our detection algorithm accumulates pixel-level correspondence in translation space. Thus it does not depone on feature top dog detection and handles patterns with low repetition counts well. For improving the robustness with multiple interfering symmetries, we introduce an see-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 exacting shapes, with the aid of the perpixel harmony information. Our proposed method is accurate, robust and ef?cient as veri?ed by an ample evaluation development a big facade material body database. The proposed ¸ method can be use to various applications in imagebased facade modeling.

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