报告内容简介:
Robust Principal Component Analysis (RPCA) by decomposing a matrix into low-rank plus sparse matrices offers a powerful tool in solving computer vision problems. However, the results by the existing RPCA-based methods are often unsatisfied in complex scenes, for example varying illumination, shape changes, occlusions and shadows etc. In this talk, an adaptive RPCA which simultaneously preserves low-rank structure and restores the corrupted parts is proposed. Specifically, the sum of weighted singular values is included in the objective function of minimization, and the weights are adaptively obtained by employing the proportion of information contained in corresponding singular values. Finally, we demonstrate several applications of the proposed methods in computer vision, such as image inpainting, shadow removal, background modeling and so on.
