Abstract: A new algorithm is proposed based on Sum of Modified Laplacian（NSML）, for the fusion problem of the multi-source images of the same scene. The traditional SML only calculates the Laplacian value of each pixel on horizontal and vertical direction, while NSML adds the four directions on the diagonal ramp. Fast NSML based on integral image is put forward in order to solve the problem that there are amounts of repeated calculations in the process of NSML. Fast NSML greatly reduces the time consumed by the fusion process and improves the efficiency of fusion by mean of simplifying the calculation process. The experimental results show that the method achieves excellent fusion of image quality, at the same time, enhances the real-time algorithm.
