Image mosaic technique can be used to acquire wide view scene without reducing the resolution. According to the characteristics of the wavelet analysis and mutual information, a new optimization algorithm of image mosaic was put forward in this paper. The optimized mosaic was realized by following means, that is, narrowing the registering region by image segmentation, optimizing calculation through wavelet decomposition and optimizing searching path by Powell algorithm. The experimental results showed that the algorithm possessed high computing efficiency and good effect of mosaic.
