Abstract

The invention discloses a video coding method and device and a computer device, and the method comprises the steps: obtaining a background image of a collection region of video collection equipment; segmenting each to-be-coded video image acquired by the video acquisition equipment into a background region and a foreground region; replacing the background area of each to-be-coded video image withthe background image to obtain a replaced to-be-coded video image; and performing video coding according to the replaced to-be-coded video image. According to the invention, each to-be-coded video image is replaced with the unified background image, so that only the changed foreground area of each to-be-coded video image is coded, and on the premise of ensuring the video quality, the compression efficiency of monitoring video coding is greatly compressed, the coding calculation amount is reduced, and the storage space is saved.

Description

technical field [0001] The present invention relates to the field of coding technology, in particular to a video coding method, device and computer equipment. Background technique [0002] Video surveillance is another major video application after digital TV and video conferencing. Thousands of cameras are linked together through a broadband network to form a "visual perception network" covering the city. The massive monitoring data collected by a large number of cameras Effective video storage is a major challenge for information technology. [0003] Surveillance videos often need to be stored for weeks or even months, and the storage cost for the entire storage of surveillance videos is very large. In order to reduce storage costs, it is often only at the cost of loss of video quality. Therefore, it is urgent to propose a video coding method to reduce the amount of calculation to improve video coding efficiency and save storage space. Contents of the invention [0004...
