摘要
分析了互信息配准的物理基础和配准原理,提出了利用差图像熵的互信息测度,对多种具有代表性的互信息测度进行了比较,并用邻域信息对差图像互信息进行了改进。试验结果表明,与空域信息相结合的互信息测度具有更好的抗噪性。
After analyzing the principle of registration based on MI, it presents an adaptation of MI by using the entropy of different image and comparing several kinds of similarity measure. Results show that the combined MI with spatial information has better anti-interference.
