In order to solve the problems of human motion intention recognition and abnormal behavior detection in home environment
a trajectory analysis based algorithm is discussed in this paper.Firstly
the home environment is divided into different key points and areas
so that the motion trajectory can be described by them.Moreover
based on mixture Gaussian model
the problems of motion intention recognition and abnormal behavior detection are analyzed.Finally
the PCA algorithm is applied to improve the accuracy of abnormal behavior detection.The experimental results show the effectiveness and reliability of the above conclusions.
