Using the discrete imagedegradationmodel, a block-based SVD filter scheme was applied for the image denoising with an automatically determined singular value rank.
This paper introduces the application background and basic methods of blind image restoration briefly, analyzes the degradationmodel of image and the ill-posed problem during restoration in detail.
