Abstract

The embodiment of the present application discloses a behavior category detection method, device, electronic equipment and computer readable medium. Embodiments of the method include: based on key frames of the target video, segmenting the target video into multiple video segments; preprocessing the segmented video segments to generate decoded data for each video segment; The decoded data is input to the pre-trained behavior category detection model to obtain the behavior category detection results corresponding to each video segment; the obtained behavior category detection results are integrated to generate the behavior category sequence of the human objects in the target video. This embodiment improves the detection accuracy of the behavior category of human objects in video frames.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, and specifically relate to a behavior category detection method, device, electronic equipment, and computer-readable medium. Background technique [0002] As the premise and means of automatic analysis and video processing, video understanding has important value and significance in video recommendation, extraction of highlights, and video tagging. For example, in videos such as film and television dramas, important behaviors are often the key to analyzing the plot of the video content. Therefore, the detection of human behavior categories on the frames in the video can provide support for video analysis. [0003] A related method is usually to divide the video evenly into video segments, and then detect the behavior categories of the human objects in the video segment by segment. However, this method cannot effectively control the number of shots in the video clip...
