Abstract

The invention discloses an image deblurring method and device. A to-be-processed image is divided into a plurality of regions based on the depth information of pixel points, a fuzzy kernel of each region is respectively calculated, for each region, the fuzzy kernel of the corresponding region is utilized to carry out deblurring processing, edge fusion of the regions after deblurring is carried outto acquire an image after deblurring, and problems of a ringing phenomenon and distortion of the deblurred image are solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, and more specifically, to an image deblurring method and device. Background technique [0002] Image blur is usually the result of relative motion between the camera and the scene (such as camera shake) during the time the camera is exposed. Due to the arbitrariness of displacement motion, the diversity of natural images, and the complexity of various noises, the image deblurring problem becomes very difficult. [0003] The purpose of image deblurring is to re-estimate the original image from the observed blurred image. Image deblurring is divided into two categories: non-blind image deblurring and blind image deblurring. If the degradation process of the image is known, that is, the blur kernel is known, then this type of image deblurring problem is called image non-blind deblurring. This type of problem has been studied very maturely, and many technologies can now be solved v...
