摘要: 为了既能让被篡改图像的结构信息得到恢复,又能让图像的细节部分得到很好的修复,提出了一种基于双份分形码解码与自适应TV算法相结合的迭代图像修复方法。该方法结合了自适应TV算法的梯度修复特性,利用原图的两种不同分形码进行迭代解码,从而实现对篡改图像结构和细节部分的修复。实验结果表明,算法对图像的结构和细节修复上都具有较好的效果。

Abstract: In order to restore the structure and the detail of the tampered image, an effective scheme is proposed to use the double fractal codes and the adaptive TV model for image recovery. In this paper, it can be iteratively used the fractal decoding of the two different image fractal codes and the adaptive TV model to restore the structure and the detail of the tampered regions. Experimental results show that this method has good restore result in both structure and detail recovery.
