Embodiment 1

[0130] The technical solutions of the present invention will be described below in conjunction with the embodiments.

[0131] combine figure 1 with figure 2 The shown method and device, for example, to detect 3 videos with a length of 30 minutes to 40 minutes, the file names of these 3 videos are file1, file2 and file3, and the format of the output advertising position is filename[a, b], Where filename is the file name, a is the start frame of the advertisement segment, and b is the end frame of the advertisement segment.

[0132] Such as image 3 Shown is the video detection flowchart in Embodiment 1 of the present invention, specifically as follows:

[0133] Step 501: Use ffmpeg software on the first video to be detected, intercept the picture according to the speed of 25 frames / s, and obtain a discretized video, the size of each image is 448 * 336, and the format is jpg;

[0134] Step 502: Use the lens segmentation algorithm to perform lens segmentation on these pictur...

Abstract

The invention discloses a method and a device for detecting television advertisements, wherein the method adopts the technical schemes comprising the following steps: generating at least one shot according to a video to be detected; extracting image features of the shot and establishing a database by using the image features, wherein the database stores advertisement shots and corresponding related information; and searching the related information stored in the database so as to detect the television advertisements that appear repeatedly. The device for detecting the television advertisementscomprises a shot generating module, a data control module and an advertisement searching module. By adopting the technical schemes, the invention can detect repeated advertisements in the video and improves the experiences of users.

Description

technical field [0001] The invention relates to the technical field of video recognition, in particular to a TV advertisement detection method and device.
