Embodiment Construction
[0075] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0076] Compared with the automatic advertisement detection method in the prior art, the method disclosed in the present invention has a great difference in the general idea. Based on the audio information in the TV program, the present invention quickly detects the advertisement in the TV program segment, without using the video information in the TV program segment like the related method in the prior art. combine Figure 9 , the specific implementation steps of the method of the present invention will be described in detail below in conjunction with an example.
[0077] Step 10. Perform preprocessing on the data in the advertisement library and the data of the radio and television programs to be detected. In the preprocessing process, the audio stream is separated from the advertisement library data or the radio and TV program data to be de...

The invention provides an advertisement detection and identification method, which comprises the following steps: preprocessing broadcast television program data to be checked to obtain the short time energy envelope of the data audio stream; according to the short time energy feature of the audio stream, dividing the obtained short time energy envelope into energy envelope units to obtain the energy envelope unit diagram of the broadcast television program data to be checked; comparing the energy envelope unit diagram of the broadcast television program data with a known energy envelope unit diagram of the advertisement through a unit skipping strategy and a similarity measurement method based on the energy envelope unit, and realizing the detection and identification of the advertisement according to comparison results. The invention which carries out advertisement detection through audio feature and integration of audio and video feature instead of through video feature has the advantages of low computation complexity and high detection efficiency. Through comparison between the data to be checked and the known audio feature of advertisement, the invention can identify specific advertisement. The invention also has the advantage of a wide application range.
Description
technical field [0001] The invention relates to the field of advertisement detection and recognition, in particular to an audio retrieval-based advertisement detection and recognition method and system. Background technique [0002] In recent years, automatic advertisement detection has played an increasingly important role in daily life, thus attracting more and more scholars' attention. For example, from the perspective of TV end users, automatic filtering of advertisements when recording programs will greatly improve user comfort and efficiency; for advertisers and companies, automatic detection of specific advertisements will be able to effectively verify the fulfillment of advertising companies. Contract situation; for social public institutions, automatic advertisement detection can help detect illegal advertisements. [0003] There are many automatic detection methods for advertisements. Early scholars mainly used rule-based methods, such as detecting and locating a...
