Contour Detection and Completion for Inpainting and Segmentation Based on Topological Gradient and Fast Marching Algorithms
Figure 4
(a) Occluded image, defined by a black square on a white background, the occlusion being represented by a red square; (b) Occluded image, defined by a black circle on a white background, the occlusion being represented by a red square; (c) Inpainted image by diffusion (see (a) for the original degraded image), without any inserted edge in the occlusion; (d) Same as (c) in the circle case; (e) Inpainted image using the missing edges identified by the topological gradient, and then diffusion to fill in the image (see (a) for the original degraded image); (f) Same as (e) in the circle case.
