For a movement target segmentation complete video r esult, it can reduce movement target search quantit y, and is of great help to effective promoting tracking speed an d accuracy. The purpose of video segmentation is to extract movement target out from background in video sequen ces and used for implementing prospect and backgrou nd segmentation. The paper researches on background de duction before tennis video human body movement tra cking and contour extracting, in the hope of exploring mo re scientific background deduction algorithm to pro vide good platform for sports video analysis. In the paper, i t firstly introduces Mean Shift algorithm and parti cle filter method algorithm. It states to algorithm that combines wit h the two algorithms, and provides LPP background e stimation algorithm and particle filter prediction algorithm principle. Use the paper algorithms to compare 3 al gorithm, and shows algorithm superiority.
