Abstract

The invention discloses a content-based video detection method and a content-based video detection device. A video program to be detected is subjected to audio decoding and audio detection by adopting a partial image decoding mode to determine a candidate region where a target segment appears first and then the only candidate region is subjected to image decoding and image detection to determine the accurate boundary of the target segment. By adopting the mode, not only the processing speed is improved greatly, but also the accurate boundary of the target segment can be given.

Description

[0001] technical field [0002] The invention relates to the technical field of video recognition, in particular to a content-based video detection method and device. [0003] Background technique [0004] With the continuous development of new media services, content-based video detection has been more and more widely used, that is, to detect a required target segment from a video. Advertisement detection is a typical application of content-based video detection. [0005] The following takes advertisement detection as an example to briefly introduce existing content-based video detection methods. In ad detection, the target segment is the ad segment. [0006] At present, the distribution channel of TV programs has extended from a single TV broadcast to various viewing terminals such as the Internet, mobile phones, and IPTV. requirements. [0007] Considering the above two factors, it is necessary to catalog the original TV programs, such as: program segmentation, adver...
