Abstract

The invention provides a video-based behavior recognition method, a video-based behavior recognition device, terminal equipment and a computer readable storage medium. The behavior recognition methodcomprises the steps of extracting a feature of a first full connection layer and a feature of a last convolution layer from an RGB frame of a video through a feature extractor; inputting the feature of the first full connection layer into a full connection long short-term memory network LSTM to carry out time sequence modeling, and inputting the feature of the last convolution layer into a convolution LSTM to carry out time sequence modeling; inputting the features subjected to time sequence modeling through the full-connection LSTM and the features subjected to time sequence modeling throughthe convolution LSTM into a joint optimization layer; and performing behavior identification on the RGB frame of the video through the joint optimization layer. The method can solve the problems thatan existing behavior recognition method is complex in background information, not high enough in time sequence modeling capacity and the like.

Description

technical field [0001] The invention belongs to the technical field of computer vision, and in particular relates to a video-based behavior recognition method, a behavior recognition device, terminal equipment and a computer-readable storage medium. Background technique [0002] Video action recognition is one of the most challenging problems in computer vision. Video behavior recognition is to use computer to automatically analyze video data to identify behavior categories. Video behavior recognition has important application value in many fields, such as intelligent video surveillance, video retrieval, human-computer interaction, etc. However, the existing behavior recognition methods have problems such as complex background information and insufficient ability to model time series. [0003] Therefore, it is necessary to propose a new technical solution to solve the above technical problems. Contents of the invention [0004] In view of this, the present invention pro...
