Embodiment Construction
[0028] The technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0029] The overall structure of the improved TLD tracking method based on improved Online Boosting and Kalman filter, such as figure 1 As shown, it contains three modules: tracking module, detection module and learning module.
[0030] (1) Tracking module: according to the selected target, a tracking point is generated in the tracking frame, and the tracking point in the sequence image is tracked by twice the L-K optical flow method;
[0031] (2) Detection module: First, a large number of detection windows are generated in a frame of image, and the target to be tracked is predicted by the Kalman filter, and a window twice as large as the previous tracking frame is generated at the predicted position. The ones that intersect with this window are selected and the ones that do not intersect are discarded. Then the remaining detection windows...
