Abstract

The embodiment of the invention discloses a video image processing method and device. The method comprises the steps of obtaining a video image, wherein the video image is the image belonging to a brightness chrominance YUV video stream; determining a blue chrominance component U and a red chrominance component V in the video image, and determining a skin color of a face in the video image according to the U and the V; carrying out skin grinding on the video image according to a brightness component Y of the video image and the skin color, carrying out hue adjustment on the skin grinded image by employing the skin color, and outputting the hue adjusted image. On the basis that the video image is featured by continuity, image optimization is carried out on the face in the video image, the background quality of the video image can be adjusted, and the quality of the video image is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a video image processing method and equipment. Background technique [0002] During a real-time video call or live video broadcast, it is necessary to collect video images in real time to form a video; after the image is collected, it will be sent to the video player through the network. In this process, there may be various defects in the video image, mainly including the following three aspects: [0003] 1. Flaws on the face itself, such as small spots; this will have a bad impact on the overall aesthetics of the person. [0004] Second, human skin does not look so healthy. [0005] 3. The impact of light and other environmental factors on the image. For example, when the ambient light is too dark, the overall image will be too dim, resulting in unclear faces. [0006] Based on the above problems that affect the quality of the video image, if the video image can be optimiz...
