摘要/Abstract

摘要： 首先利用Guided滤波器去除纹理和噪声干扰,获得图像的整体结构信息。然后,利用各向异性扩散算法中的边缘停止函数对传统的等照度线检测方法进行改进,并将其与传统图像修复优先权函数相结合。通过利用等照度线函数对纹理合成过程进行引导,来获得稳健的图像修复效果。仿真实验结果表明:本文算法在有效保持修复图像结构信息的同时,对具有光照变化的纹理也获得了比较理想的修复效果。

Abstract: A robust image inpainting algorithm based on isophote is proposed. In this algorithm, first, the whole image information is obtained using Guided filter to remove texture detail and image noise. Then, the traditional isophote function is improved with the edge stopping function in anisotropic diffusion approach and is combined with the traditional priority function. Finally, using the isophote function to guide inpainting process of the texture, the proposed algorithm obtains robust inpainting effect. Experimental results show that the proposed algorithm can preserve image structure effectively, and obtain relatively ideal inpainting effect in the aspect of texture synthesis with illustration changes.

Key words: information processing, image inpainting, isophote detection, Guided filter, inpainting priority, edge stopping function
