An Automatic Registration Method for Multi-Modal Images Based on Alignment Metric

Abstract:

There are some methods such as mutual information, alignment metric and so on. But they aim at registration of multi-modal images whose sizes are same. And there are few researches on registration of multi-modal images whose sizes are different. In this paper, an automatic registration method for multi-modal images based on alignment metric is proposed. In order to look for the best registration location of two multi-modal images, genetic algorithm is used in the method for iterative search. Alignment metric is used as the fitness function of genetic algorithm. It is proved that automatic registration for multi-modal images of different sizes can be realized. And it has high accuracy and robustness.
