Embodiment Construction

[0031] figure 1 It is an application environment diagram for the operation of the video object tracking method in one embodiment. Such as figure 1 As shown, the application environment includes a terminal 110, a server 120, and a video capture device 130, wherein the terminal 110, the server 120, and the video capture device 130 communicate through a network.

[0032] The terminal 110 may be a smart phone, a tablet computer, a notebook computer, a desktop computer, etc., but is not limited thereto. The video capture device 130 can be a camera, and is arranged at a location such as a building entrance. The video collection device 130 can send the collected video stream to the terminal 110 or the server 120, the terminal 110 or the server 120 can track the target of the video stream, and the video capture device 130 can also directly track the target of the video stream and send the tracking result to to terminal 110 for display.

[0033] In one embodiment, figure 1 The int...

Abstract

The invention relates to a method and device for tracking a video target. The method comprises the steps of: acquiring video stream, identifying a face region according to a face detection algorithm, and obtaining a first to-be-tracked target corresponding to a first video frame; carrying out extraction on the first to-be-tracked target by face features based on a deep neural network to obtain a first face feature, and adding the first face feature into a feature library; identifying a face region in a current video frame according to the face detection algorithm, obtaining a current to-be-tracked target corresponding to the current video frame, carrying out extraction on the current to-be-tracked target by the face features based on the deep neural network to obtain a second face feature, carrying out 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 from the first video frame, and in the tracking process, updating the feature library according to extracted updated face features. The continuity and robustness of tracking are improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for video object tracking. Background technique [0002] With the development of computer technology, target tracking technology has become more and more perfect and mature. It has always been a hot spot in the field of computer vision and image processing, and is widely used in intelligent monitoring, intelligent transportation, visual navigation, human-computer interaction, national defense reconnaissance and other fields. [0003] Traditional target tracking algorithms usually use one or several simple traditional feature matching algorithms to distinguish targets, such as using the color and shape features of the image itself, which are sensitive to the covering, turning, and lighting of target characters. underperformed. Contents of the invention [0004] Based on this, it is necessary to provide a method and device for video object tracking to impro...
