【摘要】：廣播電視播放過(guò)程中包含著大量的廣告,這些廣告有可能出現(xiàn)漏播,少播或違規(guī)等情況,因此工商管理部門和廣告商就需要對(duì)廣告的播出情況進(jìn)行監(jiān)控。隨著多媒體相關(guān)技術(shù)的發(fā)展,使得利用該技術(shù)進(jìn)行廣告檢索成為可能。當(dāng)前,廣播電視節(jié)目中的廣告檢索技術(shù)成為研究的熱點(diǎn),具有重要的研究意義和應(yīng)用價(jià)值。本文調(diào)研了當(dāng)前的廣告檢索技術(shù),把音頻語(yǔ)譜圖像識(shí)別技術(shù)應(yīng)用于廣告檢索,并且在此基礎(chǔ)上設(shè)計(jì)實(shí)現(xiàn)了B/S (Browser/Server)架構(gòu)的廣播電視廣告監(jiān)測(cè)系統(tǒng)。本論文主要完成以下工作： 一、對(duì)目前廣告檢索中使用的多媒體檢索技術(shù)進(jìn)行了調(diào)研,引出了利用音頻語(yǔ)譜圖像識(shí)別技術(shù)進(jìn)行廣告檢索的想法,然后實(shí)現(xiàn)了一種基于音頻語(yǔ)譜圖像識(shí)別的廣告檢索方法。該方法把每個(gè)廣告片段的音頻轉(zhuǎn)換成語(yǔ)譜圖像,并從中提取可區(qū)分的、適合索引的特征。檢索時(shí),通過(guò)特征對(duì)齊,采用基于EM(期望最大化算法)的迭代方法識(shí)別最匹配的廣告。實(shí)驗(yàn)結(jié)果表明,該方法可以快速準(zhǔn)確地從廣播電視中檢索到廣告,而且具有很好的魯棒性。 二、設(shè)計(jì)了基于SSH (Spring、Struts、Hibernate)架構(gòu)+YUI (Yahoo! User Interface Library)框架+FreeMarker模板的廣播電視廣告監(jiān)測(cè)系統(tǒng)。在設(shè)計(jì)時(shí)進(jìn)行了充分的需求分析,包括系統(tǒng)功能需求和非功能需求,給出了該系統(tǒng)的總體框架設(shè)計(jì)、接口設(shè)計(jì)、人工處理設(shè)計(jì)等。 三、實(shí)現(xiàn)了廣播電視廣告監(jiān)測(cè)系統(tǒng),給出了分層實(shí)現(xiàn)過(guò)程、部分源代碼以及界面截圖等。實(shí)現(xiàn)后的該系統(tǒng)具有界面美觀、操作簡(jiǎn)單、穩(wěn)定可靠、易擴(kuò)展、實(shí)施維護(hù)方便等優(yōu)點(diǎn)。 本文內(nèi)容來(lái)自中國(guó)科學(xué)院自動(dòng)化研究所研發(fā)的廣播電視內(nèi)容綜合監(jiān)測(cè)系統(tǒng),該系統(tǒng)是用來(lái)對(duì)廣播電視的播放內(nèi)容進(jìn)行監(jiān)測(cè),其中就包含了廣告監(jiān)測(cè)。本人在中科院自動(dòng)化研究所實(shí)習(xí)期間負(fù)責(zé)廣告監(jiān)測(cè)模塊的設(shè)計(jì)和研發(fā)。該系統(tǒng)目前已經(jīng)投入使用,并且取得了很好的效果。
[Abstract]:Radio and television broadcast process contains a large number of advertisements, these advertisements may appear missing, less broadcast or illegal situation, so the business administration departments and advertisers need to monitor the broadcast of advertisements. With the development of multimedia related technology, it is possible to use this technology for advertising retrieval. At present, advertising retrieval technology in radio and television programs has become a hot spot, which has important research significance and application value. This paper investigates the current advertising retrieval technology, applies the audio spectrum image recognition technology to the advertising retrieval, and designs and implements a B / S (browser / Server) radio and television advertising monitoring system. The main work of this paper is as follows: first, the multimedia retrieval technology used in advertising retrieval is investigated, and the idea of using audio spectral image recognition technology to carry out advertising retrieval is introduced. Then an advertisement retrieval method based on audio spectrum image recognition is implemented. The method converts the audio frequency of each advertisement fragment into the idiom spectrum image and extracts distinguishing and indexed features. In retrieval, feature alignment is used to identify the most matched ads using an iterative method based on EM (expectation maximization algorithm). Experimental results show that this method can retrieve advertisements from radio and television quickly and accurately, and has good robustness. Secondly, design Yui (Yahoo!) based on SSH (Spring Struts hibernate) architecture! User Interface Library) Framework FreeMarker template radio and television advertising monitoring system. In the design, the requirement analysis is carried out, including the functional and non-functional requirements of the system. The overall framework design, interface design, manual processing design and so on are given. Third, the broadcast and television advertisement monitoring system is implemented, and the hierarchical implementation process, part of the source code and interface screenshots are given. The system has the advantages of beautiful interface, simple operation, stable and reliable, easy to expand and easy to carry out maintenance. This paper comes from the integrated monitoring system of radio and television content developed by the Institute of Automation of the Chinese Academy of Sciences, which is used to monitor the broadcast content of radio and television, including advertising monitoring. I am responsible for the design and development of advertising monitoring module during the internship in the Institute of Automation of the Chinese Academy of Sciences. The system has been put into use and has achieved good results.
