Abstract

The embodiment of the invention provides a binary foreground compression coding method, so as to solve the problem that the existing binary foreground image coding stream needs to occupy a large bandwidth. The binary foreground compression coding method comprises steps: foreground pixel sections in the binary foreground image are marked; start coordinates and end coordinates of each foreground pixel section are recorded; and the start coordinates and the end coordinates of each foreground pixel section are coded.

Description

technical field [0001] The invention relates to video image processing technology, in particular to a binary foreground compression coding method. [0002] technical background [0003] With the rapid development of science and technology, the performance of processors has been rapidly improved, and more and more video surveillance systems have added intelligent analysis technology. Some intelligent analysis systems can separate the foreground and background in the image by performing real-time calculations on video image data, and obtain continuous binary foreground images (wherein each pixel is represented by a bit, "0" represents the background, "1 " stands for foreground). This binary foreground image can completely contain the shape and position information of foreground objects, so it has been widely used. Some distributed intelligent systems can also send the binary foreground image to the receiving end through the network after obtaining the binary foreground image ...
