Esearch on Human Posture Feature Extraction and Recognition Based on DT-SVM Optimization Algorithm
In order to determine the performance of human motion behavior in the spatial envi-ronment and achieve accurate definition of posture features,research has been conducted on the extrac-tion and recognition methods of human posture features based on the DT-SVM optimization algo-rithm.Using the DT-SVM optimization algorithm,recommend necessary pose feature nodes to deter-mine the spatial plane where human motion behavior is located.Implement gradient processing of pos-ture features,calculate the specific value of the angle vector based on the obtained contour nodes,and solve the mathematical expression for posture feature extraction and recognition.Complete the design of a human posture feature extraction and recognition method based on DT-SVM optimization algo-rithm.The experimental results show that the application of the above method can simultaneously con-trol human motion behavior in the X axis,Y axis,and Z axis directions,so that the deviation angle val-ues do not exceed 12°,which meets the practical application requirements of accurately defining hu-man posture features.
