Abstract

The invention discloses a video classification method and device. The method comprises the steps of obtaining multiple frames of images of a to-be-classified video; and respectively identifying the character and the bone key points of the character in the multiple frames of images, and respectively identifying the bone angle corresponding to the bone key point in each frame of image according to the area of the character in each frame of image. And generating a feature code corresponding to each bone key point according to the numerical change of the bone angle in the multi-frame image. And classifying the to-be-classified videos according to the feature codes. Therefore, the videos are classified through the characters in the videos without depending on video titles and video labels, so that the videos are classified more accurately. The technical problem that classification is inaccurate when videos are classified through titles or labels in the prior art is solved.

Description

technical field [0001] The invention relates to the technical field of image recognition, in particular to a video classification method and a device thereof. Background technique [0002] With the continuous emergence of small videos on the Internet, small videos have become an important role in online videos. Therefore, online video platforms need to classify small videos for users to browse. [0003] In related technologies, videos are classified by their titles or tags, but the titles and tags of small videos are often arbitrary, and it is impossible to effectively classify small videos. Contents of the invention [0004] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0005] For this reason, the first object of the present invention is to propose a video classification method, so as to classify videos through characters in the video, without relying on video titles and video tags, so that the class...
