The invention relates to an information acquisition method and device, electronic equipment and a storage medium, and the method comprises the steps: inputting a to-be-judged video frame into a first encoder, obtaining an apparent feature corresponding to the to-be-judged video frame, inputting motion information corresponding to the to-be-judged video frame into a second encoder, and obtaining a motion feature corresponding to the to-be-judged video frame; searching a priori preset apparent feature having the shortest distance with the apparent feature corresponding to the to-be-judged video frame from the plurality of preset apparent features, and searching a priori preset motion feature having the shortest distance with the motion feature corresponding to the to-be-judged video frame from the plurality of preset motion features; inputting the priori preset apparent features into a first decoder to obtain a predicted video frame, and inputting the priori preset motion features into a second decoder to obtain predicted motion information; and determining whether the to-be-judged video frame is an abnormal video frame based on the first error corresponding to the to-be-judged video frame and the second error corresponding to the to-be-judged video frame.
Description
technical field [0001] The present disclosure relates to the field of video, and in particular, to a method, an apparatus, an electronic device, and a storage medium for acquiring information. Background technique [0002] When reviewing whether a video is compliant, it can be determined whether a part of the video frame, that is, the video frame, is an abnormal video frame, so as to determine whether the video is related to an abnormal event. In the related art, a neural network for identifying abnormal video frames is trained in a supervised manner. In order to make the neural network used to identify abnormal video frames achieve high accuracy, it is necessary to collect a large number of positive samples, that is, normal video frames, and a large number of negative samples, that is, abnormal video frames. Annotated video frames and a large number of abnormal video frames, thus resulting in a high cost to implement determining whether a video frame is an abnormal video f...
