Embodiment Construction
[0033] The present invention is elaborated below in conjunction with accompanying drawing:
[0034] Such as figure 1 As shown, a kind of violent behavior recognition method based on temporal sequence guiding spatial attention provided by the present invention, the following steps:
[0035] 1) Two-stream feature extraction and fusion For the input continuous video sequence, the deep convolutional neural network is used to extract the features of the RGB image and the frame difference image respectively, and the two-stream features are fused for the temporally guided spatial attention module.
[0036] 2) The timing-guided spatial attention module uses the temporal features output by ConvLSTM to guide the spatial attention module to assign different weights to different spatial regions of the feature, and guide the network to pay attention to the moving region. Finally, the recognized categories and scores are output according to the weighted features.
[0037] Specifically, in...
