Abstract

The invention discloses a video denoising method and application and a mobile terminal. The video denoising application comprises an image acquisition unit, a noise level calculation unit, a smoothing coefficient calculation unit, a distance calculation unit, a weight calculation unit and a luminance processing unit. The image acquisition unit is suitable for acquiring an image frame sequence of a video. The noise level calculation unit is suitable for calculating a noise grade of each to-be-denoised pixel point. The smoothing coefficient calculation unit is suitable for determining a luminance smoothing coefficient of the to-be-denoised pixel point according to the noise grade and the luminance of the to-be-denoised pixel point. The distance calculation unit is suitable for calculating a distance between the to-be-denoised pixel point and each selected associated pixel point based on a block matching algorithm. The weight calculation unit is suitable for calculating a weight corresponding to each associated pixel point. The luminance processing unit is suitable for calculating a luminance weighting average value of all associated pixel points for each to-be-denoised pixel point and using the luminance weighting average value as denoised luminance of the to-be-denoised pixel point.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a method for denoising video, an application and a mobile terminal. Background technique [0002] In the application scenario of image or video acquisition, the acquired image will inevitably have signal noise. For example, pictures or videos taken in scenes such as night usually have relatively obvious noise. Image denoising is a very important link in image processing (single image processing or video frame sequence processing). [0003] At present, mainstream image denoising processing methods include various well-known edge-preserving filtering algorithms, such as bilateral filtering methods and the like. When denoising a sequence of image frames in a video, the traditional video denoising method is to perform a block matching operation on the pixels in the image frame and its adjacent pixels in space and time, and then complete the filtering operation. ...
