Embodiment 1
[0043] figure 1 A flowchart of an end-to-end behavior recognition method based on an adaptive spatiotemporal attention mechanism in this embodiment is given.
[0044] Combine below figure 1 The specific implementation process of the end-to-end behavior recognition method based on the adaptive spatio-temporal attention mechanism of this embodiment is described below.
[0045] Such as figure 1 As shown, this embodiment is based on the end-to-end behavior recognition method of the adaptive spatiotemporal attention mechanism, which includes:
[0046] Step S101: Receive a video image sequence.
[0047] In a specific implementation, videos in different monitoring scenarios are acquired, and an image sequence of consecutive frames is obtained.
[0048] For example: for home surveillance video to detect the behavior of the elderly and determine whether a fall has occurred;
[0049] For shopping mall surveillance video to detect and identify consumer shopping behavior and so on. ...
Embodiment 2
[0154] An end-to-end behavior recognition system based on an adaptive spatiotemporal attention mechanism, characterized in that it includes:
[0155] (1) image sequence receiving module, which is used to receive the image sequence of video;
[0156] (2) behavior recognition module, it is used to utilize behavior recognition model to process the image sequence of video and output behavior recognition result;
[0157] Among them, the behavior recognition model includes a temporal attention module and a main convolutional neural network, and a spatial attention module is embedded in the main convolutional neural network; the process of processing an image sequence by the behavior recognition model is:
[0158] Use the temporal attention module to adaptively distinguish the criticality of each frame of image, and assign corresponding weights to each frame of image, and input the output of the temporal attention module to the main convolutional neural network to identify behaviors;...
