Embodiment Construction

[0085] Before discussing the exemplary embodiments in more detail, it should be mentioned that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe operations as sequential processing, many of the operations may be performed in parallel, concurrently, or simultaneously. In addition, the order of operations can be rearranged. The process may be terminated when its operations are complete, but may also have additional steps not included in the figure. The processing may correspond to a method, function, procedure, subroutine, subroutine, or the like.

[0086] The "processing equipment" referred to in this context is "computer equipment", also known as "computer", which refers to intelligent electronic devices that can perform predetermined processing procedures such as numerical calculations and / or logic calculations by running predetermined programs or instructions. The device may include a processor and a m...

Abstract

The object of the present invention is to provide a method and device for acquiring video semantic information. The present invention determines the visual objects contained in the video frames by performing target extraction on the video frames in the video, and then determines the corresponding object features of the one or more video frames according to the object features corresponding to the visual objects. scene information, and finally determine the video semantic information corresponding to the video frame of the video according to the scene information. Compared with the prior art, the present invention can automatically acquire detailed and complete video semantic information based on video, saving a lot of manual resources for video semantic acquisition, and at the same time, the acquired video semantic information can facilitate subsequent video analysis or search Wait.

Description

technical field [0001] The invention relates to the field of video technology, in particular to a technology for acquiring video semantic information. Background technique [0002] At present, methods for obtaining video content mainly include: obtaining according to a video introduction, or obtaining after analyzing the video content. The former is mainly based on the video introduction, and the video content covered by the video introduction is limited and cannot reflect the specific details of the video content; the latter is mainly for character recognition and emotion recognition on the video screen, so the restored video information is limited and cannot Completely restore the specific semantic information corresponding to the video. [0003] Therefore, how to obtain detailed video semantic information and further support video applications has become one of the problems to be solved urgently by those skilled in the art. Contents of the invention [0004] The objec...
