Identification of Motion Direction from Motion Blurred Images Based on Radon Transform and Gabor Transform
Abstract：In order to recover the uniform linear motion blurred image, it' s necessary to identify the motion direction,Based on the spectrum characteristics of motion blurred image, the mathematic principle of Radon transform and procedures of using it to i- dentify the motion direction were introduced. Aiming at the spectrum characteristics of the real blurred images taken by digital camera is not obvious, an improved algorithm based on Gabor transform is proposed. The algorithm uses a "window" focusing on the spectrum center of the image to eliminate noise interference and overcome the drawbacks of Radon transform. Numerical exper- imental results show effectiveness of the presented method.
