Embodiment Construction

[0023] The present invention provides a coding and decoding scheme based on H.264 / H.265 technology for foreground and background separation. This program specifically introduces how to use H.264 / H.265 technology to realize the foreground coding and background coding of video images. The following will be described in detail through specific embodiments.

[0024] Please refer to figure 1 The encoding device shown includes: a foreground and background separation module, a background encoding judgment module, a background encoding module, a foreground encoding module, and a code stream sending module. The foreground and background separation module is used to separate the foreground and background of a frame of images; the background encoding judgment module is used to judge whether the background separated by the foreground and background separation module is encoded or not; the background encoding module is used to encode the background The judging module determines that the ...

Abstract

The invention provides an H.264 or H.265-based foreground and background coding scheme, including a step of performing foreground and background separation of one frame of image; a step of determining whether to code a separated background; a step of coding a to-be-coded background based on an intraframe coding mode, an interframe coding mode or an interframe strip coding mode of H.264 or H.265; a step of coding a separated foreground based on a strip coding mode of H.264 or H.265; and a step of sending code streams of a coded foreground and a coded background. The to-be-coded background is subjected to coding based on coding modes of H.264 or H.265, and the to-be-coded background is subjected to differentiation coding based on the intraframe coding mode, the interframe coding mode or the interframe strip coding mode of H.264 or H.265 respectively, so that compared with other coding technologies, the coding scheme provided by the invention can greatly improve the video coding efficiency, save the network bandwidth and reduce the storage resource.

Description

technical field [0001] The present invention relates to the technical field of coding and decoding, and in particular to a coding device and method for foreground and background separation based on H.264 or H.265. Background technique [0002] In video surveillance, for some scenes, especially indoor scenes, most of the time there is no moving foreground. For video surveillance, in fact, it is mainly concerned with changing prospects, such as passing pedestrians, vehicles, changing lights, etc. A scene without a changing foreground, that is, a static background, is meaningless for video surveillance. Encoding such a scene and storing the data on the hard disk is not only a waste of encoder resources, but also a waste of storage resources. If the encoded data needs to be transmitted to the back-end storage device through the network, it is also a waste of network bandwidth. [0003] A solution to the above problems is provided in the prior art. Please refer to the Chinese...
