Color image inpainting based on total variation model
整体变分模型在矢量图像修复中的应用

The goal of digital image inpainting is to restore damaged regions or remove objects in the image. Both Tural Variation (TV) method and a basic coupled method for color image were analyzed. According to a basic coupled method for color image, color images were processed based on the total variation method, which was used in inpainting gray images. Experimental results show that the improved channel coupled diffusion model is better in inpainting lost block information and removing odd objects, keeps better edges, and is effective for image denoising in color image.
