Title: METHOD AND APPARATUS FOR TRACKING VIDEO TARGET
Abstract:
A method and apparatus for tracking a video target. The method can be applied to a terminal or a server, and comprises: obtaining a video stream, and recognizing a face region according to a face detection algorithm, so as to obtain a first to-be-tracked target corresponding to a first video frame (S210); performing extraction on the first to-be-tracked target according to face features based on a deep neural network so as to obtain a first face feature, and adding the first face feature into a feature library corresponding to the first to-be-tracked target (S220); and recognizing a face region in a current video frame according to the face detection algorithm so as obtain a current to-be-tracked target corresponding to the current video frame, performing extraction on the current to-be-tracked target according to the face features based on the deep neural network so as to obtain a second face feature, and performing feature matching on the current to-be-tracked target and the first to-be-tracked target according to the second face feature and the feature library so as to track the first to-be-tracked target starting from the first video frame, and in the tracking process, updating the feature library according to extracted updated face features (S230).
