Embodiment Construction

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0051] see figure 1 , is the video image processing method of the first embodiment provided by the present invention, and the method is used to perform image enhancement processing on an image with insufficient light. The present invention is particularly suitable for processing videos whose background is not easy to change, such as video chatting. In this embodiment, the video image processing method is used to process images of video chatting under low-light con...

Abstract

The embodiment of the invention discloses a video image processing method comprising the following steps of: obtaining one frame video image; extracting and segmenting a foreground image and a background image from the video image; optimizing the foreground image; carrying out processing of multi-frame accumulation algorithm on the background image; and combining the processed foreground image and background image into one image through an image fusion algorithm. According to the video image processing method provided by the invention, the foreground image and the background image are respectively processed to ensure that the image quality can be overall increased, the image layering is enhanced and the contour of an object in the background can be clear. In addition, the invention also provides a video image processing device.

Description

technical field [0001] The invention relates to image processing technology, in particular to a video image processing method and device. Background technique [0002] With the rapid development of communication technology, video chat has become more and more popular. However, low ambient light will result in blurry images when video chatting. If the overall brightness of the image is simply increased, the face will be too bright and the background image will be blurred due to the large difference in brightness between the face and the background. At the same time, random quantum noise will appear in the image in the dark area. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a video image processing method and device. Can improve the overall video image quality. [0004] In order to solve the above technical problems, an embodiment of the present invention provides a video image processing m...
