Abstract
Disclosed are a video watermark identification method and apparatus, device, and a storage medium. The method includes: each video frame of multiple video frames of a video is divided into multiple image blocks to obtain an image sequence corresponding to the each video frame; multiple image sequences corresponding to the multiple video frames are input to a target detection model to obtain a classification result of each image block, and a feature vector of the video is obtained according to all classification results of the multiple image blocks; and the feature vector of the video is input to a watermark identification model to obtain a watermark identification probability output by the watermark identification model, and the video containing a watermark is determining in a case where the watermark identification probability is greater than or equal to a probability threshold.
