Abstract

The embodiment of the invention provides a tracking target determination method and device. The method comprises the steps that a current frame image of a to-be-determined tracking target is obtained,and alternative targets in the current frame image are determined; all the alternative targets are sent to a preset deep learning network, wherein the deep learning network is obtained by training sample images in advance and is used for extracting appearance features containing position information of pixels; first appearance features, extracted through the deep learning network, of all the alternative targets are obtained; second appearance features of first tracking targets corresponding to a previous frame image are obtained; according to the first appearance features and the second appearance features, each alternative target is matched with each first tracking target; and according to the alternative targets successful in matching, the tracking target in the current frame image is determined. Through the scheme in the embodiment, the accuracy of the determined tracking target can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for determining a tracking target. Background technique [0002] Target tracking technology is an important research direction in computer vision applications. Its task is to determine the target in the video image, track it for a long time, maintain the target identity, and finally generate a tracking track for the target. According to the generated tracking trajectory, the behavior of the target is analyzed. [0003] In the prior art, when the target is tracked, the candidate target can be detected from the first image of the target to be tracked, and the features of the candidate target can be extracted. Track the similarity between the features of the target, and determine the tracking target from the candidate targets. Among the extracted features of the candidate target, the most important feature is the appearance feature, and of course ot...
