Abstract:
A method for reducing blur from an image is described. The method includes accessing a blurred image, wherein the blurred image has a width and a length that can be different. The method further includes converting the blurred image into a frequency domain representation of the blurred image and determining an angle of blur from the frequency domain of the blurred image. The method further includes rotating the frequency domain representation of the blurred image by the angle of blur and determining a size of the blur from the rotated frequency domain representation of the blurred image. The method further includes determining a blur kernel associated with the blur, the blur kernel comprising the angle of blur and the size of said blur and de-convoluting the blurred image according to the blur kernel to reduce the blur.
