基于重构样本区域的数字图像修复算法研究

摘要

基于样本块的纹理合成修复算法（Criminisi算法）在匹配样本块时，因为使用全局搜索策略而降低了有效匹配效率。针对这一问题，重点研究了一种改进的基于样本块的数字图像修复算法。改进算法考虑到相邻像素块的相似性，对图像样本区域进行了重构，减少了样本块搜索范围，提高了图像修复效率。%For existing sample-based texture synthesis block restoration algorithm (Criminisi algorithm ) because when there is a match sample block using a global search strategy matching efficiency and reduce the problem effectively ,this paper focuses on an improved sample block-based digital image restoration algorithm ,improved algorithm taking into ac-count the similarity of the adjacent pixel block ,the image reconstruction of the sample area ,reducing the sample block search scope to improve the efficiency of the image restoration .
