Title:
VIDEO RETRIEVAL METHOD AND APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2022/007827
Kind Code:
A1
Abstract:
A video retrieval method and apparatus, a device, and a storage medium. The method comprises: obtaining a comparison video clip from a video library according to the time length of a video to be tested (S110); determining the similarity between said video and the comparison video clip by means of a target spatial-temporal neural network, a spatial-temporal convolutional layer of the target spatial-temporal neural network being configured to be capable of respectively performing two-dimensional convolution and time dimension information processing (S120); and traversing the video library and outputting the retrieval result according to the similarity (S130). According to the method, in the process that the target spatial-temporal neural network determines the similarity between said video and the comparison video clip, the spatial-temporal convolutional layer of the target spatial-temporal neural network performs two-dimensional convolution and processes spatial features of said video and the comparison video clip, and then processes time dimension information of said video and the comparison video clip. By means of a mode in which the spatial features and the time dimension information are successively processed, the low-complexity space-time feature extraction is realized.
