摘    要:相似性测度是图像配准中的重要部分之一。本文从遥感图像配准的相似性测度中选取了互信息、相关系数和差方和等三种具有代表性的相似性测度,从计算时间、锐度、对噪声的容忍性以及对多源图像配准的影响等方面,通过实验对它们的性能进行了比较和分析。实验结果表明,不同测度具有不同的有效性和适用范围。

关 键 词:遥感图像  图像配准  互信息  相关系数  差方和

Abstract:Similarity measure is a very important problem in image registration.Three typical similarity measures for remote sensing image registration are selected including mutual information,correlation coefficient and sum of squared differences.Then,the performances of these measures are compared and analyzed by the computing time,the sharpness,the sensitivity of noise and the effect on multimodal image registration.The results of experiments show that these similarity measures have different effects and performances in different application circumstances.
Keywords:remote sensing image  image registration  mutual information  correlation coefficient  sum of squared differences
