Searching and managing large archives of visual data, such as images and video, is made hard by the lack of proper integration between the visual aspects of the problem (image processing, motion estimation, feature extraction...) and its database aspects (defining visual data as data types in a database). In this paper, we argue that image database languages can be built based on feature algebr...

The non-visual effects of the color temperature of fluorescent lamps were reviewed based mainly on our recent studies with special reference to physiological aspects in humans such as arousal level, autonomic nerve system including heart rate variability, blood pressure and body temperature regulation, and sleep architecture. It was concluded that there obviously existed the non-visual effects ...

It is now widely accepted that the brain processes sensory information in a distributed, hierarchical fashion, even if the actual hierarchies are ambiguous at present [1,2]. Within hierarchies, such as that of the visual system [3] (Fig. 1), different aspects of the incoming sensory information — such as colour, texture, shape, motion and so on — are processed separately and in parallel [1]. At...

We discuss three aspects of modelling information extraction from visual data. Firstly, we discuss pre-processing issues in the context of stability and biological plausibility. Secondly, we discuss the problem of extraction of depth information from stereo data. Finally, we discuss the extraction of (almost) independent features from a data set. We use these three aspects of processing visual ...

This paper considers several aspects of natural visual attention and its link to wider notions of awareness, natural and artificial, in the context of foveated vision. It builds on a theory of abductive perception; a formal definition for an artificial or robot perceptual system, using objects represented as feature clouds. It proposes a broad, but unifying approach to several aspects of visual...

Visual backward masking is a versatile tool for understanding principles and limitations of visual information processing in the human brain. However, the mechanisms underlying masking are still poorly understood. In the current contribution, the authors show that a structurally simple mathematical model can explain many spatial and temporal effects in visual masking, such as spatial layout eff...

There is mounting evidence that language comprehension involves the activation of mental imagery of the content of utterances (Barsalou, 1999; Bergen, Chang, & Narayan, 2004; Bergen, Narayan, & Feldman, 2003; Narayan, Bergen, & Weinberg, 2004; Richardson, Spivey, McRae, & Barsalou, 2003; Stanfield & Zwaan, 2001; Zwaan, Stanfield, & Yaxley, 2002). This imagery can have motor or perceptual conten...

As Einstein has observed, "mankind's great problem is a perfection of means but a confusion of ends." Several chapters in this book present means to estimate motion between two or more image frames in rather sophisticated ways. In this chapter, we will not consider motion estimation, but rather look at the ends of motion compensation, i.e., we will consider various ways that motion vectors are ...

the architectural education along the way of creativity has often involved with the formal and physical aspects of design as an effort to read architectural artifacts through its mere external appearances. this article, however, aims to step beyond the manifestation of conventional perspectives on visual aspects of built environment. that is, an act of interpreting the architectural spaces thro...

We describe a model of visual word recognition that accounts for several aspects of the temporal processing of sequences of briefly presented words. The model utilizes a new representation for written words, based on dynamic time warping and multidimensional scaling. The visual input passes through cascaded perceptual, comparison, and detection stages. We describe how these dynamical processes ...
