Automated analysis for basketball free throw

Kinetic analysis of the sport player performance is a very important operation for players and coaches, in order to fully understand player development and abilities. Commonly this operation is done by human observation and reviewing a large amount of recorded video. Problems with the traditional way are that this is time-consuming, inaccurate, mostly neither the players nor the coaches will be able to review the whole video content or part of the recorded video, and in some cases the reviewer may overlook some important details. This paper proposes a suggested computerized kinetic analysis for basketball free throw, the paper first detects the main positions of the free throw, then analyses the player performance based on the calculated Hu moment.
