Embodiment Construction
[0081] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments.
[0082] A real-time video tracking method, the processing flow is as figure 1 As shown, it specifically includes the following steps:
[0083] (1) In the mth frame of the video, mark 1 target area ROI to be tracked, where 1 ≤ m
[0084] (2) Extract the features of the target area ROI, that is, perform steps A-G:
[0085] A. Expand the ROI by a specific ratio to get the area RExpand. The specific ratio can be calculated according to the moving speed of the tracking target;
[0086] B. Read the video data in the RExpand described in step A to obtain Video;
[0087] C. Scale the Video described in step B to a specific size to obtain VScale;
[0088] D. Divide the VScale described in step C into p sub-blocks of...
