To restore blurry image is a key problem in blind image deblurring

because of complexity of blurring information and image noise

which will affect restoration result has ring effect. To deal with these problems

propose improved algorithm based on Laplacian prior. In kernel estimation process

introduce Laplaction sharpening to strengthen edges information of image

which improve the result of kernel estimation. To suppress ring noise

adopt bilateral filtering in blur image restoration. Experimental results show that the method is more robust to artifact noise and achieves higher quality results than precious approaches on blurry image.
