一种镶嵌影像的分块直方图匹配匀光算法

摘要

针对镶嵌影像可能存在的补丁效应以及色彩不均匀现象，提出了一种利用分块影像来确定距离权值的分块直方图匹配匀光算法。通过实验，与经典马斯克匀光算法进行了对比分析。结果表明，本文算法能够改善影像质量，实现镶嵌影像色彩均衡、反差一致，有利于大幅面应急影像的实时处理。%For the possible patch effect and color uneven phenomena in mosaic images,this paper proposed a partitioned histogram-matching dodging algorithm which uses block image to determine the distance weighting.The experimental results were compared with the classical musk dodging algorithm.The results show that the algorithm can improve image quality and realize the image color balance and contrast consistency,which has advantages in real-time processing of large-format emergency images.
