Abstract
Detection and segmentation are two strongly correlated tasks, yet typically solved separately with different techniques for repetitive patterns or simultaneously solved for generic patterns. We propose a Simultaneous Detection and Segmentation model for Repetitive pattern analysis (SimDSR) in real-world images. The proposed SimDSR model implements a joint patch-contour alignment between the multi-scale over-segments, where the optimal repetitive segment is acquired by minimizing the stable alignment feedbacks. The novel joint alignment is exploited to measure the parametric warp discrepancy with the 2-D affine Lie group on pixel intensity and the Gaussian mixture L2 distance on boundaries. Thus, a repetitive segment rather than a repetitive patch is predicted gradually growing into a series of repetitions. Extensive experiments and comparative analysis have demonstrated encouraging performance of the proposed algorithm for both detection and segmentation of repetitive patterns.
