摘要: An identification method for uniform linear motion blurring direction based on second-order difference spectrum was proposed. The power of the blurred image calculated after Laplace difference, and then processed by homomorphic filtering circular low-pass filtering. attained fitting frequency points with highest amplitude selected from image. experiments were carried out using images which simulated Lenna standard blur extent being 20 pixels, mean square error detection 1.32° without additional noise 2.27° Gauss that variance 0.01. When real images, accuracy -0.54°. This proposed is proved to be available random plane adaptable noise.
