Embodiment Construction

[0050] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0051] The present invention uses content-based video analysis and retrieval technology to realize the detection and identification of video clips in TV and video programs, that is, the currently input video file or real-time streaming video as the object to be detected, and then through video analysis and retrieval methods to detect and identify Detect and identify whether the video in the video library appears in the current video stream, locate the exact position of the video segment in the stream to be detected, and output the detection result. The video segment here can be a video sub-segment or a complete video.

[0052] A method for detecting video clips in the present invention, such as figure 1 shown, including the following steps:

[0053] Step 101: Ex...

Abstract

The embodiment of the invention discloses a video clip detecting method and device, and belongs to the field of image processing. The video clip detecting method comprises the steps that a currently-input video file or real-time streaming video is used as an object to be detected, whether video in a video library appears in the current video stream or not is detected and recognized through the video analysis and retrieval method, the accurate position, in the stream to be detected, of a video clip is located and a detection result is output. Image features extracted through the video clip detecting method and device integrate image global information and image local information, the matching error rate is reduced while the high recall rate is guaranteed, robustness is kept for image content changes, therefore, accurate locating is conducted on video clips in real-time or off-line television programs or video programs and accurate detection and recognition of the video clips are kept on the conditions that frames of video streams are lost, mosaic blocks appear in the video streams, video resolution ratios and video frame rates are different and video contents change.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for detecting video segments. Background technique [0002] Nowadays, with the development of video recording equipment software and hardware technology, more and more videos are produced by professionals or ordinary people. In the broadcasting industry, the quantity and data volume of video materials and TV program videos are very large. In managing these massive video data, it is a common and important operation to quickly obtain one or some of them according to specific needs, such as: looking for video material, program content, advertisement clips, etc. with the same video content. [0003] At the same time, with the rise of Internet video sites, hundreds of thousands of videos are uploaded every day. The video data owned by each video site is massive, and the storage overhead is very high. If users upload similar videos, the storage space will be wasted....
