直线运动模糊图像复原的截断奇异值分解方法
Linear motion blurred image restoration based on TSVD
摘要
Abstract
The image restoration problem with symmetry and translational invariance of the point spread function can be transformed into ill-posed deconvolution problem under the assumption of the Neumann boundary condition, and thus can be used TSVD method to solve. But the point spread function of in any direction linear motion blurred images does not have symmetry. While the linear motion blurred image caused merely by the interactions between pixels of the movement direction, in this paper a segments the blurred image with a series of straight parallel lines in the direction of motion, motion blur on each line can be considered similar to the level linear motion blur, the point spread function of the level linear motion blur is symmetry, thus it can restore the blurred image using TSVD method. Numerical experiments are given to illustrate the efficiency of our algorithm.关键词
