%X An improved image registration method based on pseudo-perspective model and comparametric function was presented.Firstly,computation of corner match was performed to improve the matching stability and operation speed.Secondly,an approximation of the camera's nonlinear response function was accomplished with a constrained piecewise linear one,and the joint registration model was well established.Then the more precise initial parameters could be obtained with a computationally attractive least squares method.Lastly,optimal iteration algorithm was performed to reduce the registration error.The experimental results show that the method is doing well to solve the problem of exposure difference between images and improves the speed of iteration meanwhile.
