Image blur caused by uniform linear motion and its removal using traveling wave equation and Hough transform

This paper studies restoration of images blurred caused by uniform linear motion and its spatial domain processing. Horizontal motion is taken as the canon case, 1 -dimensional traveling wave equation is adopted as the mathematical model for image blurring, and Hough transformation is applied to detection of the motion direction. As for oblique motions, they are transferred to horizontal ones for easy solution. Experimental results show that the deblurred images resulting from this spatial domain processing are of better quality than that from traditional frequency domain processing where the ring effects will more or less appear and the computing cost is high.
