A representation of visual complexity of real world scenes

Gamification of Visual Search in Real World Scenes

How Chromaticity Guides Visual Search in Real-World Scenes

To study visual attention during search processes, numerous studies measured the selectivity of observers’ saccadic eye movements for local display features. These experiments almost entirely relied on simple, artificial displays with discrete search items and features. Recently, a first study on saccadic selectivity in real-world scenes was conducted, demonstrating visual guidance by low-level...

the effect of task complexity on lexical complexity and grammatical accuracy of efl learners’ argumentative writing

بر اساس فرضیه شناخت رابینسون (2001 و 2003 و 2005) و مدل ظرفیت توجه محدود اسکهان (1998)، این تحقیق تاثیر پیچیدگی تکلیف را بر پیچیدگی واژگان و صحت گرامری نوشتار مباحثه ای 60 نفر از دانشجویان زبان انگلیسی بررسی کرد. میزان پیچیدگی تکلیف از طریق فاکتورهای پراکندگی-منابع تعیین شد. همه ی شرکت کنندگان به صورت نیمه تصادفی به یکی از سه گروه: (1) گروه موضوع، (2) گروه موضوع + اندیشه و (3) گروه موضوع + اندی...

Visual Knowledge Representation of Moving Scenes

A framework for the representation of visual knowledge, with particular attention to the analysis and the representation of scenes with moving persons and objects is described. Our aim is to integrate in a principled way the models developed within the artificial vision community, and the propositional knowledge representation systems developed within symbolic AI. We claim that this integration...

Anticipation in Real-World Scenes: The Role of Visual Context and Visual Memory

The human sentence processor is able to make rapid predictions about upcoming linguistic input. For example, upon hearing the verb eat, anticipatory eye-movements are launched toward edible objects in a visual scene (Altmann & Kamide, 1999). However, the cognitive mechanisms that underlie anticipation remain to be elucidated in ecologically valid contexts. Previous research has, in fact, mainly...
