基于透明度的单幅运动模糊图像运动参数估算方法研究

摘要

Aiming at the problem of motion parameter estimation for the blurred image, this paper analyzes the present research situation of the motion parameters estimation based on the single-blurred image. Then it starts from the perspective of transparency, and studies the relationship between the transparency and the local motion blur image. After discussing the method of using matting technique to determine the blur pixels of the single blurred image in order to estimate motion parameters, the paper puts forward improvements in the separation defocus blur of motion blur and the judgment of motion parameters change.%　　针对模糊图像中运动参数估算的问题，分析了单幅模糊图像中运动参数估算的研究现状，并从透明度的角度出发，研究了透明度与局部运动模糊之间的关系，讨论了如何采用抠图技术去确定单幅模糊图像中的模糊像素进而获取运动参数，并在分离散焦模糊对运动模糊的影响和分析运动参数的变化方面提出了改进思路。
