[0061] Embodiment 1. Robust weighted local multi-task sparse tracking method
[0062] figure 1 It is a schematic flow chart of a tracking method according to an embodiment of the present invention, which mainly includes the following steps:
[0063] Step S200, initialize the target template, that is, in the first frame, initialize the target template T=[T 1 ,T 2 ,...,T m ];
[0064] Step S210, divide each of the above-mentioned target templates into K sub-blocks, and use the k-th local blocks of the m target templates to obtain the corresponding template dictionary Among them, k=1,...,K, Represents the color histogram feature corresponding to the k-th local block in the i-th target template;
[0065] Step S220, using Gaussian random sampling (taking the state variable of the t-1th frame as the mean value and the constant as the variance) to obtain n candidate target particles in the tth frame;
[0066] Step S230, using the same blocking method as the above-mentioned t...
