Embodiment Construction
[0076] The general idea of the technical solution in the embodiment of the application is as follows:
[0077] First, in order to further improve the performance of the low-rank sparse representation tracking model (LRST), the Lp norm is introduced, and a new tracker minimization model (Lp-LRST) is proposed; the DSST tracker is used to roughly estimate the target Position and scale, and calculate the corresponding PSR value, which is used to measure the credibility of the tracking result estimated by DSST in the current frame; then, judge the relationship between the value of PSR and the set threshold, if the PSR is greater than or equal to the set threshold, Then execute the Lp-LRST tracker according to the target position and scale determined by the current frame of DSST, otherwise, the Lp-LRST tracker will re-determine the target position according to the target state of the previous frame; then, for the DSST tracker, if the PSR is greater than or equal to Set the thresho...
