A multi-scale image inpainting algorithm based on GMRF model
Rui Wang, Dongbing Gu, Guangwen Liu, Junxi Sun · 2009
A novel approach to image inpainting is introduced in this paper. The novelty lies in the combination of the MRF inpainting technique and a multiscale information fusion mechanism. This combination uses both local information via the MRF technique and global information via the multi-scale mechanism to improve the image inpainting quality. The proposed algorithm consists of three steps. In the first step, the image to be inpainted is decomposed into multiple levels via a multi-scale decomposition. In the second step, the image of each level is inpainted based on the MRF model. Finally, the multi-scale inpainting results of all levels with different scales are fused. The experimental results show that the proposal inpainting algorithm achieves fairly good results.
