在網(wǎng)絡(luò)和多媒體技術(shù)越來越發(fā)達(dá)的今天

1、摘 要在網(wǎng)絡(luò)和多媒體技術(shù)越來越發(fā)達(dá)的今天，信息檢索技術(shù)成了現(xiàn)在計(jì)算機(jī)領(lǐng)域的重要內(nèi)容，而圖像檢索技術(shù)又正是這其中的重要內(nèi)容之一。而網(wǎng)絡(luò)資源的極大豐富以及圖像檢索技術(shù)不斷發(fā)展成熟，使得圖像檢索技術(shù)的應(yīng)用領(lǐng)域不斷擴(kuò)大，這為圖像檢索技術(shù)的繼續(xù)研究提供條件。人們?yōu)榱藢D像進(jìn)行更好的使用和組織管理，便開發(fā)出了多種多樣圖像檢索技術(shù)，本文首先要將各種圖像檢索技術(shù)的工作原理、研究現(xiàn)狀、相關(guān)圖像搜索引擎與發(fā)展趨勢作一個(gè)介紹。隨著網(wǎng)絡(luò)傳送速度與計(jì)算機(jī)信息處理速度的提高，網(wǎng)頁中對多媒體信息的使用變得十分普及，特別是圖像信息，己經(jīng)成為表示網(wǎng)頁內(nèi)容不可缺少的組成部分。在實(shí)現(xiàn)對網(wǎng)頁中文本信息提取的同時(shí)，如何再為用戶抽取所需

2、的圖片資料，是信息檢索中一個(gè)重要的方面。于是各種基于Web的圖像檢索系統(tǒng)應(yīng)運(yùn)而生。它們采用不同的工作方式，極大地方便了用戶對網(wǎng)上圖像進(jìn)行檢索。目前圖像檢索技術(shù)的發(fā)展正走向更加成熟和完善，其中Web圖像搜索技術(shù)也更加完善，本文將介紹這種圖像檢索技術(shù)并闡述Web頁中的圖像與文本之間的關(guān)系，對相似度作出了詳細(xì)的論述。關(guān)鍵字: 搜索引擎 圖象檢索 文本處理 信息檢索 相似度 相關(guān)性反饋 Study of Web Images Retrieval TechniqueAbstractToday, the network and multimedia technology are more and more
