摘　　要：根据Reinhard的颜色传输算法和Welsh的灰度图像彩色化算法的不足,提出了一种基于象素空间相关性的灰度图像彩色化算法,该算法经过像素匹配,Welsh改进和分块处理和自身校正等过程,实现了灰度图像彩色化。实验结果对比证明,该算法比Welsh算法在处理速度上更快,还原效果更好。According to the disadvantages of Reinhard colour transfer algorithm and Welsh grey image-colorizing algorithm,this paper proposes a grey image colorizing algorithm based on pels space relativity.This algorithm realized the grey image colorizing by using pels matching,ameliorating,fragmental processing and oneself emendating Welsh,etc.The experiment result shows the algorithm is quick processing speed and the better deoxidization effect than Welsh.
