In order to improve the performance of image mosaic,an automated image mosaic approach was proposed based on adaptive simulated annealing and multiresolution strategy.In the first step of the algorithm,the registration region is adaptively chosen.Then,the parameters of image translation and rotation are optimized based on mutual information with a hybrid method of adaptive simulated annealing for global searching and a multiresolution approach as a local search strategy,and the process of image mosaic is fi...
