Design of a linear motion estimator based on the properties of human motion perception

To simplify the problem of estimating the motion parameters, in this paper, based on the properties of human motion perception we present a feasible approach, which can estimate the motion direction and the motion extension for a linear motion blurred image. Two main parts are developed in our approach. Hough transform is first used to detect the angle (i.e., motion direction) of a given linear motion blurred image, and quadtree method is secondly used to estimate the extent of point spread function of the same image. Many experimental results have confirmed the feasibility of the proposed approach.
