Considering the needing of manual operation in traditional image mosaic,an automatic image mosaic method based on image inherent characteristic was introduced.This method realized pixel accuracy image automatic mosaic by using the coarse-to-fine technology.An affine transform model was applied in the coarse stage;Fourier-Mellin transform technology and multi-resolution technology were combined to resolve the coarse parameters.By using the sum of grayscale difference between corresponding image areas as the similarity measurement and using the coarse parameters as the initialization,LevenbergMarquardt optimization method was applied for optimizing the perspective transformation parameters and the fine parameters could be gained in the global view.In the end,this method was effectively applied for real visible and infrared images mosaic.
