Contour Detection and Completion for Inpainting and Segmentation Based on Topological Gradient and Fast Marching Algorithms
Figure 7
(a) Three selected keypoints on the original image; (b) Contours identified by the fast marching algorithm applied to the standard gradient with the three selected keypoints (see (a)); (c) Contours identified by the fast marching algorithm applied to the topological gradient with the three selected keypoints (see (a)).
