Abstract

The invention discloses a human body behavior recognition method based on self-feedback gene expression programming. According to the method, for a deep human body behavior image, three-dimensional time series data of a plurality of joints of the human body are extracted from the image as samples; modeling is carried out on the samples by using self-feedback gene expression programming constructed by adding a TIS insertion string operation into gene expression programming after intersection and variation, thereby obtaining a human body motion model, wherein the TIS insertion string operation indicates the operation of inserting a function string into a joint motion sequence head; and then gradient information is extracted as a model feature. The model characteristics of the human body motion model of the training sample are input to a neural network and training is carried out to obtain a neural network model as a human body behavior classifier; and model characteristic of a human body movement model corresponding to a tested sample are inputted into the obtained human body behavior classifier to obtain a human body behavior recognition result. The method has advantages of high human body behavior identification accuracy and fast identification speed.
