As sporting events become more and more competitive;
many coaches are beginning to use information technology to improve the professionalism of their athletes. Monitoring and recognition of moving objects in sports video is currently a more common method. However;
the uniqueness of basketball sports video poses a great challenge to target tracking techniques;
especially the interference of camera shake and noise. This works suggests an athlete tracking method based on an improved Gaussian mixture model as a solution to the concerns mentioned above. Firstly;
the problem of stereo visual perception in basketball sports videos is investigated. Secondly;
the background modelling method based on the traditional Gaussian mixture model is analysed;
and the background model parameter estimation method is constructed using the Student-t distribution. The parameter estimation is completed by the expectation-maximum algorithm and the parameter space is partitioned. Then;
in order to further improve the accuracy of target tracking;
a particle filtering optimization algorithm based on genetic algorithm was proposed in order to eliminate the particle degradation. Finally;
two video sequences of NBA regular season games were used for target tracking tests. The experimental results show that the proposed improved Gaussian mixture model has better target tracking results compared with the traditional Gaussian mixture model and the generalised Gaussian mixture model. The tracking accuracy of the athletes is higher;
which validates the effectiveness and advancedness of the proposed model. © 2024 ISSN 2414-8105;
