商品描述
At its very core multimedia information retrieval means the process of searching for and finding multimedia documents; the corresponding research field is concerned with building the best possible multimedia search engines. The intriguing bit here is that the query itself can be a multimedia excerpt: For example, when you walk around in an unknown place and stumble across an interesting landmark, would it not be great if you could just take a picture with your mobile phone and send it to a service that finds a similar picture in a database and tells you more about the building -- and about its significance, for that matter? This book goes further by examining the full matrix of a variety of query modes versus document types. How do you retrieve a music piece by humming? What if you want to find news video clips on forest fires using a still image? The text discusses underlying techniques and common approaches to facilitate multimedia search engines from metadata driven retrieval, via piggy-back text retrieval where automated processes create text surrogates for multimedia, automated image annotation and content-based retrieval. The latter is studied in great depth looking at features and distances, and how to effectively combine them for efficient retrieval, to a point where the readers have the ingredients and recipe in their hands for building their own multimedia search engines. Supporting users in their resource discovery mission when hunting for multimedia material is not a technological indexing problem alone. We look at interactive ways of engaging with repositories through browsing and relevance feedback, roping in geographical context, and providing visual summaries for videos. The book concludes with an overview of state-of-the-art research projects in the area of multimedia information retrieval, which gives an indication of the research and development trends and, thereby, a glimpse of the future world.

在其核心,媒體資訊檢索意味著搜尋和找到多媒體文件的過程;相應的研究領域則專注於建立最佳的多媒體搜尋引擎。這裡有趣的是,查詢本身可以是一段多媒體摘錄:例如,當你在一個陌生的地方走動,偶然發現一個有趣的地標時,如果你能用手機拍張照片並將其發送到一個服務,該服務能在數據庫中找到相似的圖片並告訴你更多關於這座建築及其意義的信息,這不是很好嗎?本書進一步探討了各種查詢模式與文件類型的完整矩陣。你如何通過哼唱來檢索一段音樂?如果你想用靜態圖片來查找有關森林火災的新聞視頻片段呢?文本討論了促進多媒體搜尋引擎的基本技術和常見方法,從元數據驅動的檢索,到自動化過程為多媒體創建文本替代品的附加文本檢索,再到自動圖像標註和基於內容的檢索。後者深入研究特徵和距離,以及如何有效地將它們結合以實現高效檢索,讓讀者手中擁有建立自己多媒體搜尋引擎的材料和配方。支持用戶在尋找多媒體材料時的資源發現任務,不僅僅是一個技術索引問題。我們探討了通過瀏覽和相關反饋與資料庫互動的方式,結合地理上下文,並為視頻提供視覺摘要。本書最後概述了多媒體資訊檢索領域的最先進研究項目,這顯示了研究和開發的趨勢,從而讓人窺見未來的世界。
