Setyawan, I. (author), Lagendijk, L. (author)We present in this paper the results of our study on the human perception of geometric distortions in images. The ultimate goal of this study is to devise an objective measurement scheme for geometric distortions in images, which should have a good correspondence to human perception of the distortions. The study is divided into two parts. The...conference paper 2004

Van Doorn, A.J. (author), De Ridder, H. (author), Koenderink, J.J. (author)Pictorial relief depends strongly on “cues” in the image. For isoluminant renderings some cues are missing, namely all information that is related to luminance contrast (e.g., shading, atmospheric perspective). It has been suggested that spatial discrimination and especially pictorial space suffer badly in isoluminant conditions. We have...conference paper 2005

Bittermann, M. (author), Ciftcioglu, O. (author)Implications of design decisions are hard to oversee for designers. This is the case in particular with respect to decisions, which influence perception related qualities of designs. Such qualities are for example visual openness, visual privacy, and spatial intimacy. They are difficult to measure because of their subjective and soft nature....conference paper 2006

Del Castillo C., A. (author), Wever, R. (author), Buijs, P.J. (author), Stevels, A.

Due to a retail landscape consisting of large stores, displaying packed products on the shelves in self-service environments, these aspects become increasingly important, not only for Fast Moving Consumer Goods, but for consumer durables...conference paper 2007

Quist, W. (author), Van Hees, R. (author), Naldin, S. (author), Nijland, T. (author)By means of a questionnaire a study was carried out to investigate the perception of small scale damage and repairs of natural stone used in buildings. Participants were asked to evaluate damage to natural stone shown on pictures. They were also asked to give their opinion on interventions needed to preserve or restore the material. Significant...conference paper 2008

Heyndrickx, I. (author), Kaptein, R. (author)A lot of current 3D displays suffer from the fact that their spatial resolution is lower compared to their 2D counterparts. One reason for this is that the multiple views needed to generate 3D are often spatially multiplexed. Besides this, imperfect separation of the left- and right-eye view leads to blurring or ghosting, and therefore to a...conference paper 2009

Ten Holt, G.A. (author), Arendsen, J. (author), De Ridder, H. (author), Van Doorn, A.J. (author), Reinders, M.J.T. (author), Hendriks, E.A. (author)Current automatic sign language recognition (ASLR) seldom uses perceptual knowledge about the recognition of sign language. Using such knowledge can improve ASLR because it can give an indication which elements or phases of a sign are important for its meaning. Also, the current generation of data-driven ASLR methods has shortcomings which may...conference paper 2009

Slinger, J.H. (author)At the 2008 System Dynamics Conference in Athens a survey of the understanding and expectations of conference participants regarding model analysis was conducted. Respondents included both those active in research on formal model analysis methods and those only vaguely familiar with the term. Results from the survey are presented and discussed...conference paper 2009

Cruz, P.J.S. (author), Veer, F.A. (author), Carvalho, P.L.L. (author)The application of glass in contemporary architecture explores perceptual phenomenon that intentionally change the way we experience space. SANAA'S recent work uses glass in a radical way, proposing a renewed approach to transparency. The Toledo Glass Pavilion, with most spaces defined by glass walls, presents an intense visual experience. The...conference paper 2010

Koenderink, J. (author)The egg-rolling behavior of the graylag goose is an often quoted example of a fixed-action pattern. The bird will even attempt to roll a brick back to its nest! Despite excellent visual acuity it apparently "takes a brick for an egg." Evolution optimizes utility, not veridicality. Yet textbooks take it for a fact that human vision evolved so as...conference paper 2011

Van Doorn, A.J. (author), Wagemans, J. (author), De Ridder, H. (author), Koenderink, J.J. (author)A "picture" is a at object covered with pigments in a certain pattern. Human observers, when looking "into" a picture (photograph, painting, drawing, . . . say) often report to experience a three dimensional "pictorial space." This space is a mental entity, apparently triggered by so called pictorial cues. The latter are sub-structures of color...conference paper 2011

We conducted a psychophysical experiment in which observers rated optical mixtures of the three combinations of glossy, matte, and velvety green birds. The observers rated the materials on four scales: matte-glossy...conference paper 2012

(author)We present a novel setup in which real objects made of different materials can be mixed optically. For the materials we chose mutually very different materials, which we assume to represent canonical modes. The appearance of 3D objects consisting of any material can be described as linear superposition of 3D objects of different canonical...conference paper 2012
