Vision-based human action recognition provides an advanced interface
and research in this field of human action recognition has been actively carried out. This paper describes a scheme for recognizing human actions from a video sequences. The proposed method is an extension of the Motion History Image(MHI) method based on the ordinal measure of accumulated motion
which is robust to variations of appearances. We define the accumulated motion image(AMI) using image differences firstly. Then the AMI of the video sequencesis resized to a MN regulation following the standard of training phases. Finally
we employ Support Vector Machine(SVM) as a classifier to distinguish the current activity in target video sequences. In a word
our proposed algorithm not only outperforms the state of art on public available KTH data set and Weizmann data set
but also proves practical to some real world applications
in addition
this method is computationally simple and able to achieve a satisfactory accuracy.
