Propose a motion state recognition method based on 3 d dynamic characteristics
first USES a star skeleton structure characterization of the human body 3 d motion
through GMM for image sequence foreground image
ISOMAP nonlinear dimension reduction of manifold learning method is used to generate a low dimensional data subspace
the motion of 3 d data projection to nonlinear flow pattern in the low-dimensional subspace
and identify the motion state of inner structure of human body movement is conducted for each key points of the study
based on the integration of learning have hidden markov study so that can be used to automatically identify the motion state. The simulation experimental results show that the recognition speed and accuracy of this method compared to traditional methods have obvious improve
