商品描述

Although William James declared in 1890, "Everyone knows what attention is," today there are many different and sometimes opposing views on the subject. This fragmented theoretical landscape may be because most of the theories and models of attention offer explanations in natural language or in a pictorial manner rather than providing a quantitative and unambiguous statement of the theory. They focus on the manifestations of attention instead of its rationale. In this book, John Tsotsos develops a formal model of visual attention with the goal of providing a theoretical explanation for why humans (and animals) must have the capacity to attend. He takes a unique approach to the theory, using the full breadth of the language of computation--rather than simply the language of mathematics--as the formal means of description. The result, the Selective Tuning model of vision and attention, explains attentive behavior in humans and provides a foundation for building computer systems that see with human-like characteristics. The overarching conclusion is that human vision is based on a general purpose processor that can be dynamically tuned to the task and the scene viewed on a moment-by-moment basis. Tsotsos offers a comprehensive, up-to-date overview of attention theories and models and a full description of the Selective Tuning model, confining the formal elements to two chapters and two appendixes. The text is accompanied by more than 100 illustrations in black and white and color; additional color illustrations and movies are available on the book's Web site

商品描述(中文翻譯)

威廉·詹姆斯於1890年宣稱「每個人都知道什麼是注意力」,然而如今對於這個主題存在著許多不同且有時相互對立的觀點。這種理論上的分裂可能是因為大多數關於注意力的理論和模型都是以自然語言或圖像的方式提供解釋,而非提供定量且明確的陳述。它們著重於注意力的表現而非其基本原理。在本書中,約翰·索索斯以目標為在提供人類(和動物)必須具備注意力能力的理論解釋為目標,發展了一個視覺注意力的形式模型。他採用了一種獨特的方法,使用計算語言的全部範疇(而非僅僅數學語言)作為形式描述的手段。結果,選擇性調整視覺和注意力模型解釋了人類的注意行為,並為構建具有類似人類特徵的計算機系統提供了基礎。總體結論是,人類視覺基於一個通用處理器,可以根據任務和每一刻所觀察到的場景動態調整。索索斯提供了對注意力理論和模型的全面且最新的概述,以及對選擇性調整模型的詳細描述,其中形式元素僅限於兩章和兩個附錄。本書配有100多幅黑白和彩色插圖;額外的彩色插圖和影片可在書籍網站上獲得。
