Embodiment Construction

[0016] The present invention is further described in conjunction with the following examples.

[0017] see figure 1 , a video image denoising system of the present embodiment, comprising a model building module 1, a noise removal module 2 and a denoising evaluation module 3, the model building module 1 is used to establish a video image noise model, and the noise removal module 2 For removing video image noise according to the noise model, the denoising evaluation module 3 is used for evaluating the denoising effect of the noise removal module 2;

[0018] The model building module 1 is used to set up a video image noise model, specifically:

[0019] Taking each frame of image in the video sequence as an image block, the video image noise model is expressed as:

[0020] H=F+N+M

[0021] In the formula, F represents a clean image matrix without noise, F={f 1 ,f 2 ,..., f l},f i Represents the i-th clean image block, l represents the number of image frames, i=1,2,...,l, N ...

Abstract

The invention provides a video image denoising system. The system comprises a model building module, a denoising module and a denoising evaluation module; the model building module is used for building a video image noise model; the denoising module is used for denoising a video image according to the noise model; and the denoising evaluation module is used for evaluating a denoising effect of thedenoising module. The system has the beneficial effects that accurate denoising of the video image and effective evaluation of the denoising effect are realized.

Description

technical field [0001] The invention relates to the technical field of image denoising, in particular to a video image denoising system. Background technique [0002] Vision is one of the main ways for humans to obtain information. Images play an extremely important role in human work and life. Image processing refers to the key technology for extracting information from images, which is widely used in various aspects of industry and life, such as agricultural production, oil exploration, biomedicine and other fields. As a fundamental task in image processing, image denoising provides a solid foundation for image analysis and understanding. [0003] In the stages of image acquisition, compression, and transmission, due to the influence of various factors such as the environment and transmission channels, the image will be disturbed by noise, resulting in loss of image information and distortion. Processing distorted images will inevitably affect the results of image proce...
