Problems solved by technology

Its disadvantage is that it cannot analyze the abnormal behavior of the logo in the video stream and accurately locate the time point of the abnormal occurrence
In addition, the existing station logo detection and recognition methods are usually only applicable to the recognition of certain types of station logos and are not universal
In addition, the existing station logo detection and recognition technology does not provide an effective solution to the situation when station logo detection and recognition errors occur

Embodiment Construction

[0054] A method and device for identifying a logo in a video according to an embodiment of the present invention will be described in detail below with reference to the accompanying drawings.

[0055] The invention mainly solves the detection and identification of station logos in broadcast television and network television programs, and conducts real-time analysis and detection on the behavior of station logos, and sends out alarm information and the start and end time of station logo abnormalities if abnormalities are found. At the same time, the present invention can also be used for the detection, identification and positioning of logos similar to station logos in videos and static pictures.

[0056] The station logo can be divided into two categories according to whether it is moving: static station logo and animation station logo. The characteristic of the static station logo is that the shape of the station logo does not change or changes slightly; the characteristic of...

Abstract

The embodiment of the invention discloses an identification method and a device of a station caption in a video, and belongs to the field of image processing. The method comprises the steps of inputting extracted image features into a main station caption classifier corresponding to a program to be detected, zooming a current video image to different scales, performing slide detection on the zoomed image according to the established step size with a classifier window in a multi-scale manner, positioning a main station caption, obtaining a candidate station caption image area, and obtaining a sub station caption through pixel division and similarity calculation, so that the station caption in the video program is detected and positioned in real time, and identified; behaviors of the station caption are analyzed in real time; abnormal behaviors of the station caption are further acquired; start time points and stop time points of the abnormal behaviors of the station caption and corresponding types of the behaviors can be presented accurately; the method has good generality and robustness, and is applicable to detection and identification of various station captions.

Description

technical field [0001] The invention belongs to the field of image processing, and relates to a method and a device for identifying a station logo in a video. Background technique [0002] At present, in the process of program production by TV stations, in order to declare copyright, a logo representing copyright will be inserted into the video program content, usually the station logo image of the program channel. The station logo includes identification information of the TV station and the channel, thereby distinguishing it from other TV stations and channels. In the process of making the program, due to the mistakes of the staff, some abnormalities will occur during the insertion of the logo, such as the disappearance of the logo (that is, the logo has not been inserted into the video for a certain period of time), the error of the logo (that is, a certain The logo of another channel is inserted in the video for a period of time), the logo shifts (that is, the logo in t...
