Human behavior recognition method and device, computer device, and storage medium

Abstract

This application provides a method, apparatus, computer device, and storage medium for human behavior recognition, belonging to the field of computer vision technology. The method includes: acquiring a sequence of behaviors to be recognized; acquiring a template behavior sequence; performing alignment calculations based on a preset diagonal matrix and an initial column vector to be recognized to obtain a target aligned behavior sequence; calculating the similarity between the template behavior sequence and the target aligned sequence to obtain a sequence similarity; and determining the behavior recognition result of the target object based on the sequence similarity. This application first converts the sequence of behaviors to be recognized into a target aligned behavior sequence aligned with the template behavior sequence using a diagonal matrix, and then determines the behavior recognition result of the target object based on the sequence similarity between the target aligned sequence and the template behavior sequence. Because this application performs an alignment operation before sequence matching, it can improve the accuracy of behavior recognition.
