Title:
IMAGE DENOISING METHOD AND APPARATUS, STORAGE MEDIUM AND TERMINAL
Document Type and Number:
WIPO Patent Application WO/2020/140986
Kind Code:
A1
Abstract:
Disclosed are an image denoising method and apparatus, a storage medium and a terminal. The method comprises: determining brightness information of a skin color area in a target image; determining, in the skin color area, a target sub-area with the brightness lower than a pre-set brightness threshold value, and determining a target denoising intensity according to the brightness of the target sub-area and the brightness information; and performing, based on the target denoising intensity, denoising processing on the target sub-area to obtain a target image subjected to denoising processing. By using the technical solution, by means of determining, based on the brightness, a target sub-area to be subjected to denoising processing, determining the denoising intensity according to the brightness of each pixel point in the target sub-area and brightness information of a skin color area, and performing, based on the denoising intensity, denoising processing on a corresponding pixel point, the effect of locally denoising the skin color area based on the brightness is achieved, such that noises in the skin color area are distributed more uniformly.
