摘要: 首选讨论水平方向匀速直线运动所导致的图像模糊的去除,包括运动方向和位移量的探测和原始图像的递推求取,然后推广到任意方向的匀速直线运动上.实验结果表明这样的空间域处理可以避免传统的频率域处理中必有的振铃效应和迭代求解的高计算量.Abstract: The relative motion between a camera and the scene will lead to blurred images. Note that the linear motion of an object can be described by the traveling wave equation. This model may be used for explaining the formation of the above image blur and for its restoration in spatial domain as well. Investigations in this paper are first made on the removal of image blur caused by a uniform, linear motion along the horizontal direction, including the detection and measurement of the motion direction and displacement, and a recursive solution of the original image; then on the generalization of the method to 2-D case so as to suit the uniform linear motion along an arbitrary direction. The experimental results show that the ring-bell effect inherent from traditional frequency domain processing as well as the expensive iterations in solution can be avoided by such a spatial domain processing.
