The invention provides a video classification method and device, and relates to the technical field of video processing, and the method comprises the steps: obtaining text information of a to-be-classified video; wherein the text information of the to-be-classified video is used for describing the to-be-classified video; determining a video feature vector of the to-be-classified video according tothe text information of the to-be-classified video; wherein the video feature vector of the to-be-classified video is obtained by clustering word vectors corresponding to corpora in a corpus; determining a classification result of the to-be-classified video according to the video feature vector of the to-be-classified video and the classification model; wherein the classification model is determined by the video feature vector corresponding to the text information of the historical video. According to the method for determining video classification in the embodiment of the invention, the calculation and processing expenditure of the steps of video decoding, frame extraction, frame feature extraction and the like on the original video can be avoided, the classification result of the targetvideo can be obtained more quickly, and the classification efficiency is improved.
Description
technical field [0001] The present invention relates to the technical field of video processing, in particular to a video classification method and device. Background technique [0002] When video service providers provide video services to users, they often need to classify videos according to video content. On the one hand, video service providers can display videos by category on web pages or mobile terminal applications, which can help users find interesting videos more quickly. On the other hand, by determining the category of the video in advance, it can also provide convenience for searching and recommending the video. [0003] In the prior art, video classification has been developed from manual classification to machine classification. In machine classification, a common method is to use a pre-trained image classification convolutional neural network (CNN) to classify the videos to be classified in the video. However, when CNN is used to classify the video to be c...
