VIDEO ANALYSIS METHOD AND RELATED MODEL TRAINING METHOD, DEVICE AND APPARATUS THEREFOR

摘要

Disclosed in embodiments of the present application are a video analysis method and a related model training method, device and apparatus therefor. The video analysis method comprises: obtaining a video to be analyzed; performing feature extraction on said video by using a preset network model to obtain a first multi-dimensional feature map, wherein the first multi-dimensional feature map comprises feature information on different timings corresponding to said video; predicting the first multi-dimensional feature map by using an offset prediction network to obtain offset information; performing timing offset on at least part of the feature information of the first multi-dimensional feature map by using the offset information, and obtaining a second multi-dimensional feature map on the basis of the offset feature information; and analyzing the second multidimensional feature map by using the preset network model to obtain analysis result information of said video.
