Method and device for image deblurring

Abstract

The present application discloses an image deblurring method and device, comprising: acquiring a blurred picture and a DVS event set within an exposure time; using the blurred picture as a current blurred picture; and performing deblurring processing on the blurred picture according to the DVS event set. By applying the present application, the effect of image deblurring can be improved.

Description

technical field [0001] The present application relates to image processing technology, and in particular to an image deblurring method and device. Background technique [0002] When the camera is taking pictures, sometimes due to various reasons such as hand shaking, the picture may be blurred. In order to remove or reduce image blur caused by camera motion, deblurring processing is usually performed on the imaged blurred image to obtain a clearer image. [0003] At present, the existing deblurring methods can achieve deblurring effects only for a small number of images. The reason for this is that the existing technology uses deconvolution to achieve deblurring, and the process of using deconvolution to achieve deblurring itself is a pathological process, because the clear image and the cause of the blurring of the clear image are unknown in advance. of. It is precisely because the reason for the blurring of the image is unknown, so many methods will make some assumption...

The reason for this is that the existing technology uses deconvolution to achieve deblurring, and the process of using deconvolution to achieve deblurring itself is a pathological process, because the clear image and the cause of the blurring of the clear image are unknown in advance. of

It is precisely because the reason for the blurring of the image is unknown, so many methods will make some assumptions about the clear image to be solved. However, when the actual image does not match the assumption, the deblurring method will fail
