Image Deblurring Method Based on Fourier Transform

Image blurring caused by motion and camera jitter is a common phenomenon nowadays, and blurring directly leads to the decline of image quality. The paper provides an image deblurring method based on Fourier transform. The method includes treating the blurring problem as an inverse problem. Firstly, the blurred image is preliminarily de-noised to remove part of the noise and improve the image quality. Then, the original clear image and the blur calculator are estimated respectively by double iteration method. The experimental results show that our method has good deblurring effect.
