Title:
VIDEO BEHAVIOR IDENTIFICATION METHOD AND APPARATUS, STORAGE MEDIUM AND SERVER
Document Type and Number:
WIPO Patent Application WO/2020/232886
Kind Code:
A1
Abstract:
The present application relates to the field of computer technology, and proposes a video behavior recognition method and apparatus, a storage medium and a server. Said method comprises: firstly acquiring a video to be identified, and extracting multiple video images from the video to be identified; and then inputting the multiple video images into a pre-trained neural network model, so as to obtain a behavior identification result output by the neural network model. In the present application, the following data processing logic is added to the structure of the neural network model: acquiring image processing data of the multiple video images, the image processing data being a four-dimensional matrix containing global image feature information; performing convolution processing on the four-dimensional matrix to obtain a four-dimensional matrix containing local image feature information; and respectively tiling the four-dimensional matrix containing the global image feature information and the four-dimensional matrix containing the local image feature information, and then multiplying same, so that the local feature and the global feature of the video image are combined. The present invention can improve the accuracy of video behavior identification.
