本文针对多光谱图像配准中不同光谱图像间存在较大的灰度差异、同一景

物在不同波段表现的特征也各不相同等问题，提出了基于互信息相似性测度的

多光谱图像配准算法。-In this paper, multi-spectral image registration between images in different spectral gray there is a big difference, the same scene in different performance characteristics of band varies and so on, based on mutual information similarity measure for multi-spectral image registration algorithm .
