Embodiment Construction

[0050] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0051] In the prior art, the commonly used video compression algorithm directly compresses the entire video image, which reduces the video transmission cost, but also affects the definition of human faces in the video.

[0052] In order to solve the above-mentioned technical problem, the present invention provides a kind of video compression method, by acquiring video image, according to carrying out skin color analysis to each frame image in described video image, obtain the human face image and background image in described each frame image; Gaussian blur processing is performed on the background image to obtain a blurred background image; compression processing is performed on the blurred background image. The present invention can realize the recognition of the area where the face is located in the image during th...

Abstract

The invention discloses a video compression method. The method includes: acquiring a video image; carrying out skin color analysis on each frame image in video images to obtain a face image and a background image in each frame image; carrying out Gaussian blurring on the background image to obtain a blurred background image; and carrying out compression on the blurred background image. The invention also discloses a video compression device and a computer-readable storage medium. The method can achieve effects that in a video chat process, clarity of face information in a video process can beguaranteed, and video bandwidth can also be reduced.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a video compression method, device and computer-readable storage medium. Background technique [0002] With the development of the economy and the Internet, the way of communication between people has gradually changed. Video chat has gradually replaced ordinary language and has become an important way for people to communicate and communicate in work or daily life. [0003] The video information in the video chat process is composed of frames of images, but the current video images contain a lot of redundant information, which takes up a lot of bandwidth in the process of video digital transmission, which affects the running cost and video quality. fluency. However, in order to reduce operating costs and improve video fluency, many compression methods have emerged, such as JPEG and MPEG methods. [0004] However, the current compression method will compress all the cont...
