The Extraction And Trace Of Body Joint In Image Sequence

In recent years, kinetic analysis becomes more important in graphic management and computer visual. It can detect, identify and trace persons from kinetic pictures and describe persons' movement. At the meantime, it can be widely used in intelligence supervision and virtual environment. After the success in applying for providing Olympic Games in 2008 in Beijing, it is highly important that kinetic analysis system would used in motion information and then achievement would be promoted. Kinetic analysis system deals with pictures shot by vidicon. After removing background, using joint detecting algorithm to detect joints and reconstructing joints'coordinates of two dimensions in three dimensions space, parameters got are applied in kinetic analysis. The main content in this paper is how to get information of joints when matching accuracy and how to use it in kinetic analysis system. A better algorithm ASS depended on FSS is introduced accompanied by a new matching criterion relied on texture.
