Embodiment Construction

[0027] As mentioned in the background art, there is an urgent need for a method for efficiently classifying video scenes.

[0028] The inventors of the present invention have found through research that in the prior art, convolutional neural networks are usually used to classify images for scenes, but since videos usually involve many complex scenes, existing solutions cannot efficiently classify videos for scenes Classification.

[0029] In order to solve the above technical problem, an embodiment of the present invention provides a video scene classification method. In the solution of the embodiment of the present invention, the image sequence of the input video is divided according to the scene similarity between two adjacent frames of images to obtain multiple image subsequences. Since the scene similarity between two adjacent frames of images in each divided image subsequence exceeds the first preset threshold, it can be judged that the scenes of the images in each image...

Abstract

A video scene classification method and device, a storage medium and a terminal, the method comprising: acquiring an input video, and extracting an image sequence from the input video, the image sequence comprising a plurality of frames of images, each frame of image having a time label; inputting the multiple frames of images into a scene classification model to obtain a scene classification result of each frame of image; dividing the image sequence according to the scene similarity between two adjacent frames of images to obtain a plurality of image subsequences, and determining the scene classification result of the input video according to the scene classification result of each image subsequence and the time information of the image subsequence. Through the scheme of the invention, scene classification can be carried out on the video.

Description

technical field [0001] The present invention relates to the technical field of computer vision, in particular to a video scene classification method and device, a storage medium, and a terminal. Background technique [0002] With the development of the Internet, a large amount of data is generated every moment, including a large amount of video data. With the widespread application of smart devices (eg, mobile phones, tablet computers, etc.), users can conveniently browse various videos. Efficiently understanding video content is beneficial to providing users with faster and more convenient video services. In addition, the understanding of video content also has a high application prospect in the field of intelligent surveillance. Efficiently understanding the content of video is conducive to improving the work efficiency of intelligent surveillance systems. Scene classification of video is a prerequisite for understanding video content, and there is a lack of methods for ...
