Abstract

Blind image restoration has always been a hot and difficult problem in the field of image processing. As the vertical motion blur image has obvious characteristics in the frequency domain, the distance between the center point and the nearest horizontal black strip is automatically estimated by setting thresholds, and the estimated vertical motion point spread function is obtained; the image is blindly restored by the constrained least squares algorithm. Experimental results show that the proposed vertical motion point spread function estimation algorithm has high accuracy, and the restored image has better visual effects and higher PSNR.
