Blind Image Restoration using the Cepstrum Method

Much research has been conducted on blind image restoration using the cepstrum method for degradations caused by out-of-focus and motion blurring due to the camera's focus settings and/or camera's motion that lead to a uniformly blurred image. The restoration of an image with a still background and a moving object is seldom addressed in the literature. This paper presents a method that extracts the blurred object from the background first, and then estimates the parameters of the PSF using the cepstrum method. Final restoration is achieved by using a classical Wiener filter. Experimental results show that the proposed method is able to achieve satisfactory restored images
