The present invention provides a video classification method and device, which relate to the technical field of video processing. The method includes: acquiring text information of the video to be classified; using the text information of the video to be classified to describe the video to be classified; determining the video according to the text information of the video to be classified The video feature vector of the video to be classified; the video feature vector of the video to be classified is obtained by clustering the word vectors corresponding to the corpus in the corpus; according to the video feature vector of the video to be classified and the classification model, the classification of the video to be classified is determined Results; the classification model is determined by the video feature vector corresponding to the text information of the historical video. The method for determining video classification in the embodiment of the present invention can avoid the calculation and processing overhead of steps such as video decoding, frame extraction, and frame feature extraction on the original video, can obtain the classification result of the target video more quickly, and improve classification efficiency.
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...
