Summary: | A violent behavior intelligent detection method based on video analysis adopts an intensive trajectory extraction algorithm to obtain motion feature points on a video picture, tracking the obtained motion feature points and calculating the positions of the motion feature points on a plurality of continuous video frames, so as to obtain a motion trajectory corresponding to the motion feature points; training a convolutional neural network of spatial flow to obtain a convolutional neural network model based on spatial detection, and utilizing the model to extract a spatial feature layer of a video; training a convolutional neural network of time streams to obtain a convolutional neural network model to obtain a convolutional neural network model based on time detection, and utilizing the model to extract a time feature layer of the video; pooling the extracted motion trajectory on the neural network feature layers, calculating to obtain three-dimensional feature vectors based on trajectory and depth feature fus |
