Articulated Human Motion Tracking Using Sequential Immune Genetic Algorithm
Algorithm 3
S-IGA-based motion tracking algorithm.
(1) Initialization: perform human pose estimation on the first frame of the video, output the | converged antibodies , where ; | (2) for do | (3) Next-frame propagation: randomly propagate the antibodies to enhance their diversities | according to the following transition model: | , ; | (4) IGA-based pose optimization: using Algorithm 2 to optimize the initial antibodies: | ; | (5) Check the convergence criterion: if satisfied, the converged antibodies are used to initial | the next frame; | (6) The individual with best affinity in population is used to | approximate the tracking result of time ; | (7) end for. |
