Motion Blur is one of the common artifacts in digital photographing. With the population of handheld camera and smart phone, image deblurring becomes an important problem. Richardson-Lucy algorithm is well-known deconvolution algorithm. But the ringing artifacts usually appear while the estimated point spread function is not accurate. In this paper, we(More)
Motion blur is an ill-posed problem which has been addressed for a long time in digital photographing. It usually happens under the circumstance without enough surrounding light. Several methods have been proposed for this problem. However, the ringing is inevitable artifacts arising in the deconvolution stage. To suppress undesirable artifacts,(More)
