Embodiment 1
[0107] In order to more clearly generate the implementation process of the video target tracking method of the embodiment of the present application, the following uses the KCF algorithm in combination with the Median Flow algorithm to illustrate the entire target tracking process. The tracking process includes the following steps:
[0108] A1. Obtain a video;
[0109] A2. Determine the occurrence frame of the target to be tracked in the video;
[0110] A3. In the appearing frame, or in the appearing frame and several frames after the appearing frame, use a rectangular frame to mark the target. The marking process should meet the following requirements: try to mark the target within the rectangular frame, and reduce the size of the rectangular frame as much as possible;
[0111] A4. Record the corner coordinates, length and width of the upper left corner of the rectangular border;
[0112] A5. Start the KCF algorithm module and the Median Flow algorithm module to analyze the ...

Abstract
The invention relates to the technical field of video tracking, and particularly discloses a video target tracking method and device, electronic equipment and a storage medium, and the method comprises the following steps: obtaining video information; setting initial tracking target information according to the video information; acquiring scale change information of the video information according to the initial tracking target information on the basis of a tracking algorithm which has a scale change tracking characteristic and performs tracking by using an L-K optical flow method under the condition of not performing target position tracking; respectively adjusting the position and the scale of the initial tracking target information according to the position change information and the scale change information so as to track the target in the video information; according to the method, accurate tracking including scale and position parameters can be rapidly carried out on the target in the video information.
Description
technical field [0001] The present application relates to the technical field of video tracking, and in particular, to a video object tracking method, device, electronic equipment, and storage medium. Background technique [0002] Video target tracking technology is the technology of locating targets in continuous frames of video. [0003] Video object tracking is widely used in various fields, such as intelligent video surveillance, visual navigation, medical diagnosis, virtual reality, etc. [0004] In the prior art, video target tracking generally uses one of Boosting, MIL, KCF, TLD, Median Flow, GOTURN, MOSSE and CSRT algorithms for tracking; these algorithms have different functions, principles, effects, and speeds, and the tracking operation speed is fast The tracking algorithm cannot obtain the feature of the target size change in the video (ie, the scale feature), and the tracking algorithm that can obtain the feature of the target size change in the video has a fas...
