Embodiment Construction
[0022] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0023] An embodiment of the present invention provides a human behavior recognition algorithm, the human behavior recognition algorithm includes the following steps: according to the depth information of the video sequence, extracting the corresponding STDF feature;
[0024] Extract the STDF features of the sampling points, and establish the BoW model based on the LPM model;
[0025] Using SVM based on RBF kernel function to analyze the data in the established BoW to get the results.
[0026] Preferably, the specific steps of extracting the STDF feature of the sampling point are:
[0027] Calculate the motion salient area...
