(a) Occluded image (black rectangle) by a red rectangle; (b) Inpainted image using the standard topological gradient; (c) Minimal path between the keypoints represented on the topological gradient; (d) Inpainted image using the hybrid scheme (fast marching algorithm for closing the contours identified by the topological gradient); (e) Inpainted image using a TV-based method.
