Abstract: This paper studies the direction of arbitrary uniform linear motion blurred image of the fuzzy algorithm to determine the direction of the main motion blur in accordance with the direction of the movement to reduce the high frequency components of the image along the movement direction of the implementation of high-pass filtering, we can make sure gray differential image value (absolute value) and the smallest, the paper is on the basis of this principle to determine a uniform motion blur direction of motion-blurred images using the 3 × 3 direction of the differential multiplier method to determine the direction of motion-blurred images, which can be the restoration of the image is transformed into one-dimensional problem.
