Abstract
The invention discloses a monitoring video moving target detection method based on an intra-frame coding compression domain. According to the method, a monitoring video moving target detection method based on the intra-frame coding compression domain is established; the established system comprises an intra-frame residual background frame obtaining module, a moving feature information obtaining and processing module and a moving target obtaining module; intra-frame residual background frames are obtained through the intra-frame residual background frame obtaining module; moving feature information is obtained and processed through the moving feature information obtaining and processing module; and a moving target is obtained through the moving target obtaining module. According to the method, on the basis of the video compression domain, only the intra-frame coding frame residual information needs to be extracted, so the complexity is low and the real-time operability is high; when transmission distortion such as packet loss occurs, the method relatively robust; the moving target is extracted precisely; and the anti-noise capability is high.
Description
technical field [0001] The invention relates to the field of monitoring video moving target detection, in particular to a monitoring video moving target detection method based on intra-frame coding compression domain. Background technique [0002] Moving object detection refers to the detection of moving foreground objects from video, which is a hot issue in the field of computer vision and the basis for subsequent operations such as object recognition and analysis. Moving object detection includes two cases of camera stillness and camera movement. Camera stillness generally corresponds to the scene of surveillance video, and the background is generally static. The difficulty of moving target detection lies in the influence of factors such as small changes in the background, noise, object shadows, and weather. In the case of camera movement, the correction of the overall movement of the background should be considered emphatically. [0003] Common moving target detection m...
