Motion Blur Direction Estimation Using Radon Transform

(1) Apply motion blur to the original image, perform Fourier transform to obtain the corresponding frequency spectrum. (2) Perform Canny operator edge detection on the motion-blurred image's frequency spectrum. (3) Apply Radon transform to the Canny edge detection result to determine motion blur direction.
