Description
In this paper, we present a novel structure-guided framework for exemplar-based image inpainting to maintain the neighborhood consistence and structure coherence of an inpainted region. The proposed method consists of a data term for pixel validity and boundary continuity, a smoothness term to depict the compatibility of neighboring pixels for contextual continuity, and a coherence term to investigate image inherent regularities to ensure image self-similarity. To better reconstruct image structures, the method utilizes image regularity statistics to extract dominant linear structures of the target image. Guided by these structures, homography transformations are estimated and combined to globally repair the missing region using the Markov random field model. To reduce computational complexity, a hierarchical process is implemented to utilize the regularity effectively. The experimental results demonstrate that our …
