Embodiment Construction

[0082] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0083] The present invention aims at the inaccurate recognition of offset images in the prior art, and provides a TV advertisement detection method based on the position of the station logo. The offset is estimated by pre-calculating the position of the station logo, and then the TV advertisement is carried out. The detection method improves the accuracy of television advertisement detection.

[0084] Before advertising detection, two template libraries should be b...

Abstract

The invention discloses a TV commercial detection method and a TV commercial detection system based on channel logo position. The method comprises the steps of acquiring a real-time TV video, extracting a channel logo name and a channel logo position from the real-time TV video, acquiring a channel logo position template corresponding to the channel logo name from a channel logo template library, determining the channel logo offset quantity according to the channel logo position and the channel logo position template, shifting each frame of image in the real-time TV video in a set period of time according to the channel logo offset quantity to obtain a shifted image, extracting image features of the shifted images to obtain image feature sequences, judging whether an image feature sequence template contains all or part of the image feature sequences exists in a commercial template library, and outputting the channel logo name and a commercial name corresponding to the image feature sequence template in the commercial template library if an image feature sequence template contains all or part of the image feature sequences exists in the commercial template library. According to the invention, the problem of matching error caused by image offset is solved, and the accuracy of commercial detection is improved.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a TV advertisement detection method and system based on the position of a station logo. Background technique [0002] The TV video detection system in the prior art is mainly used to detect the name of the currently playing advertisement from the video, and calculate the start time of the advertisement, which has great practical value and market prospect. The specific method is to use a pre-established advertisement model to match the video information of the currently playing advertisement, and theoretically it can be well detected which advertisement template the currently playing advertisement belongs to. However, in practical applications, there will be some changes in the same advertisement, such as image distortion, frame loss and the overall offset of the advertisement picture, etc. These interference factors will cause the advertisement detection to fail, thus restricting ...
