Abstract

The invention relates to a facial information acquisition method and device, and the method comprises the steps: extracting facial features from a video frame set of a target video, and obtaining a target facial feature corresponding to each video frame in the video frame set; clustering faces included in the target video according to the video frame set and the target face features correspondingto each video frame to obtain a target face category and category face features corresponding to the target face category; identifying target facial information corresponding to the category facial features in a facial information base, the facial features and the facial information having a corresponding relationship being recorded in the facial information base; and outputting target face information corresponding to the target face category. According to the invention, the technical problem of low efficiency of recognizing the face information from the video in related technologies is solved.

Description

technical field [0001] The present application relates to the field of computers, in particular to a method and device for acquiring face information. Background technique [0002] Recognizing the participating characters from the video and marking the position where the character appears in the video is the key technology of video intelligent analysis, which has very important meanings in the application field of multimedia (movies, TV dramas, variety shows, etc.). At present, the main recognition method is based on artificial intelligence. This method obtains the picture information of each second of the video by sampling frames of the video, and then extracts the facial features through the deep neural network, and finally searches and recognizes them in the face database. , to get information about who the face is. The disadvantage of this method is that for every second of the face in the picture, it needs to go to the face database for retrieval, which increases the n...
