Abstract

The invention discloses an image rain removing method and device. The method comprises the following steps of: outputting a coding characteristic image of a rain image by utilizing an encoder network; according to the coded feature image, outputting an attention feature image, indicating a rain area, of the rain image by utilizing an attention model; and outputting the rain-removed image of the rain image by using a decoder network according to the coded feature image and the attention feature image. According to the invention, raindrops in the image can be more effectively removed, the original information of the image can be better reserved, and the quality of the rain-removed image can be improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for removing rain from an image. Background technique [0002] Deraining research on images and videos is an important topic in the field of computer vision and image processing. Inclement weather conditions can cause a series of loss of visibility, altering the content and color of images. Such signal distortion and loss of details lead to the failure of many computer vision applications applied outdoors, which usually take high-quality images as input. The raindrops in the image will cause serious intensity fluctuations in small areas of the image, resulting in blurred images, making rainy images unsuitable for many computer vision applications. Therefore, the research on image deraining has important practical significance. [0003] There are mainly three existing image deraining methods: 1. Deraining method based on image processing knowledge; 2. Deraini...
