Embodiment Construction

[0046] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] refer to figure 1 , which shows a flow chart of the steps of Embodiment 1 of a method for image denoising according to the present invention, which may specifically include the following steps:

[0048] Step 101, using a coding network to perform feature extraction on the original picture data to obtain picture feature information, wherein the picture feature information includes noise information;

[0049] In a specific implementation, the original picture data may be a picture with noise. As an example, the original picture data may be a picture with irregular stripe noise, for example, a ID photo with irregular stripe noise.

[0050] In the embodiment of the present invention, the encoding network may be a deep convolut...

Abstract

Embodiments of the present invention provide a method and device for image denoising, wherein the method includes: using a coding network to perform feature extraction on original image data to obtain image feature information, wherein the image feature information includes noise information; The picture feature information is input into the decoding network for denoising processing, and the target picture data is output. This application provides the automatic removal of noise information in pictures with streak noise by using encoding network and decoding network. It has effective noise removal effect for pictures of various sizes, and the efficiency of noise removal is high, and the noise removal effect is obvious.

Description

technical field [0001] The present invention relates to the technical field of picture processing, in particular to a picture denoising method and a picture denoising device. Background technique [0002] In daily life, it is usually necessary to perform de-stripe noise processing on ID photos with streak noise. In the prior art, the method of removing stripes from a picture containing irregular stripe noise generally includes the following process: [0003] (1) Determine the area where noise needs to be removed; [0004] (2) Different methods are used to fill the noise area. [0005] The method adopted in step 1 is generally boundary segmentation, and threshold value processing is performed to find the target area. The problem that often occurs in this step is that due to the influence of the content of the picture itself, the segmentation algorithm cannot accurately locate the noise area, and due to the complexity of the picture, there are huge differences in the select...
