Abstract

The invention discloses a GMPHD video multi-target tracking method fusing correlation filtering, and belongs to the technical field of computer vision, mode recognition and information processing. According to the method, a target is tracked by adopting a related filtering thought, and intersection ratio judgment of image information is added to carry out target template updating-free and parameter processing on the shielded target, so that pollution of a target template is reduced, and mistaken following frames are reduced. According to the method, a shielded target is put into Gaussian mixture probability hypothesis density filtering to perform position prediction updating operation, and if the target reappears in the later period, the target label is associated again, so that fragmentedtracks are reduced, and the defect of missing detection of a detector is overcome. Finally, a result on an MOT17 data set proves that compared with the best tracking algorithm GMPHDOGM17 related to GM-PHD at present, the multi-target tracking accuracy MOTA index is improved to 50.3 from the original 49.9.

Description

technical field [0001] The invention relates to a GM-PHD video multi-target tracking method with fusion correlation filtering, and belongs to the technical fields of computer vision, pattern recognition and information processing. Background technique [0002] Video multi-target tracking is an important research field in the field of computer vision, which has many applications such as intelligent surveillance, human-computer interaction, behavior recognition, robot navigation and automatic driving. Multi-object tracking can assign consistent labels to tracked objects in each video frame to produce a trajectory for each object. At present, multi-target tracking is mainly divided into two types: online tracking and batch tracking. Online tracking refers to real-time tracking using only the past and present information of the video, which is more in line with the needs of people's scenarios, and is suitable for applications with strong real-time requirements such as intellige...
