(a) Admissible set of keypoints and selected keypoints on the topological gradient; (b) Minimal path between the keypoints represented on the topological gradient; (c) Minimal path between the keypoints represented on the occluded image; (d) Corresponding identified missing edge in white; (e) Inpainted image using the fast marching algorithm for closing the contours identified by the topological gradient in the hidden part of the image; (f) Zoom of (e).
