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

The embodiment of the invention provides an image de-noising method and an image de-noising device. The method comprises the following steps of carrying out feature extraction on original image data by adopting an encoding network, and obtaining the image feature information, wherein the image feature information comprises noise information; inputting the image feature information into a decodingnetwork for performing the de-noising treatment on the information, and outputting target image data. The invention provides the method for automatically removing the noise information in images withstripe noises by adopting the encoding network and the decoding network. Therefore, the effect of effectively removing noises is achieved for images of various sizes. The noise removing efficiency ishigh, and the noise removing 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...
