基于重构样本区域的数字图像修复算法研究

Digital Image Inpainting Algorithms Based on Restoration of Exemplar Block

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 account 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.
