Exemplar-Based Image Completion Using Color Ratio Gradient

A new algorithm in Exemplar-Based image completion is proposed using color Ratio Gradient. Color Ratio Gradient Histogram is robust to object occlusion and clustering which induce mismatch in general image match algorithm. The proposed algorithm can improve the quality of comparing similarity between source image patch and target image patch, then improve the quality of image completion. Experimentation results show that the proposed method improve the quality of image completion compared with previous algorithms.
