Image Inpainting Using Multiscale Salient Structure Propagation

In this study, a new image inpainting approach using multiscale salient structure propagation is proposed. The proposed approach consists of four stages, namely, (1) detection of salient structure(s), (2) inpainting of salient structure(s), (3) inpainting of surrounding areas of salient structure(s) by modified ant colony optimization (ACO), and (4) inpainting of remaining missing regions. Based on the experimental results obtained in this study, as compared with four comparison approaches, the proposed approach provides the better image inpainting results.
