According to the problems of the limited range of the camera,complex factors with the electronic noise,X-ray scattering and uneven illumination,they often disturb the doctor's diagnosis.This paper developed a new medical images registration and mosaic algorithm based on Retinex and SURF algorithms.Firstly,the algorithm took three edge filter to improved the multi scale Retinex method to enhance the images,it also used the phase correlation power spectrum to estimate the overlap region and reduced the range ...
