A target tracking system and method based on csk and tld fusion algorithm

Abstract

The present invention proposes a target tracking system and method based on the fusion algorithm of CSK and TLD, belonging to the field of computer vision, including: an initialization module, a CSK tracking module, a judgment module, a TLD module, an integration module, and a result output module; the TLD module includes optical flow Method tracker, cascade detector; Cascade detector is formed by cascading of variance detector, random fern detector and nearest neighbor detector; The target tracking method based on CSK and TLD fusion algorithm of the present invention overcomes the single use The CSK algorithm has the problem of easy tracking failure under complex background interference, and the problem of complex structure, slow running speed and difficulty in realizing real-time performance when using the TLD algorithm alone. The present invention has wider adaptability to target tracking in complex scenes, and greatly improves the tracking accuracy while ensuring real-time performance. It can be seen through simulation experiments that the tracking results of the traditional CSK algorithm have a large offset, while the present invention The method is able to re-detect the target and thus track successfully.

Description

technical field [0001] The invention belongs to the field of computer vision, in particular to a target tracking system and method based on a fusion algorithm of CSK and TLD. Background technique [0002] With the development of society and the improvement of computer level, video surveillance can be seen everywhere. However, the traditional monitoring system only uses human eyes to observe abnormalities in the video, which is time-consuming and labor-intensive, and can no longer meet people's needs. Intelligent monitoring systems have emerged as the times require. The intelligent monitoring system uses intelligent algorithms and related theories of computer vision to automatically detect, identify and track abnormalities in video sequences, liberate the labor force, and provide convenience for people's production and life. [0003] Target tracking is closely related to target detection and target recognition. In the actual application process, before using a specific track...
