Important features are extracted by domain color determination and field segmentation, including sports field color, texture, spatial ratio, motion texture and camera shot-time motion. And then, various ball games are classified based on ICA and SVM.

• 通过对球类比赛进行主色确定、场地分割,提取场地颜色、纹理、空间比例、运动纹理及摄像机短时运动等特征,在此基础上用ICA和SVM对各种球类运动进行特征优化和分类,取得了较好的效果。
