摘要: 从图像配准的模糊性出发,在图像配准中考虑图像的灰度相关性,结合了图像的空间信息。在配准准则中引入图像配准的灰度相关系数,提出了基于模糊互信息的配准准则。实验表明,模糊互信息函数比互信息函数具有更少的局部极值点和更好的优化特性。

Abstract: Intensity correlation coefficient which considered fuzzy character of image has been introduced into image registration. A new similarity measure which combines spatial information of image is developed. Experiment results show that similarity measure based on fuzzy mutual information has less local extremums and better optimization character.
