Abstract
This application provides a target tracking method, including: obtaining a plurality of consecutive picture frames of a target video, and setting a tracked target region of an npicture frame; performing a feature extraction operation on the tracked target region of the npicture frame, to obtain a feature map of the tracked target region; calculating a weighted filter corresponding to the input feature map according to a correlation filter algorithm and a mean pooling constraint condition; calculating an output response of an (n+1)picture frame by using the weighted filter and an input feature map of the (n+1)picture frame in the plurality of consecutive picture frames, and determining a tracked target region of the (n+1)picture frame according to the output response of the (n+1)picture frame, until tracked target regions of all the consecutive picture frames are obtained. This application improves precision and effectiveness of target tracking.
