Effect of Lightness on Blackness Preference of Black Fabrics

In this paper, the effect of lightness on blackness preference of 216 black fabrics prepared by printing method is investigated. 18 observers including of 9 males and 9 females are asked to firstly rank order black fabrics with the same lightness values according to their preference. In the next step, observers are asked to define their blackness preference for blacks with different L values. R...

Critical Factors in the Design of Playful Learning Environments: Reflections on “the Return of the Incredible Machine: Contraptions”

This paper analyzes and makes explicit design principles that underline the software game The Return of The Incredible Machine: Contraptions,”. In order to do this it takes into account two complementary perspectives – educational software engineering and theories of learning through play and games. One goal of the analysis is to identify the specific design features that make edutainment softw...

Assessing of Fabric Appearance Changes Using Image Processing Techniques

 This paper describes the use of image processing to measure lightness changes of fabric appearance. The lightness changes due to dyeing, washing and exposure to light treatments are studied. These properties are measured by using the changes in the intensity levels of the fabrics image and the L* obtained by a spectrophotometer. For each case, analysis of variance (ANOVA) is carded out and the...

Occlusion, transparency, and lightness

The lightness of a visual surface is its perceived achromatic reflectance [Adelson, E. H., (2000). Lightness perception and lightness illusions. In M. Gazzaniga (Ed.), The new cognitive neuroscience (2nd ed.) (pp. 339-351) Berlin: Springer; Gilchrist, A. (1999). Lightness perception. In R. W. F. Keil (Ed.), MIT encyclopedia of cognitive science (pp. 471-472). Cambridge: MIT press]. Lightness ra...

A cortical edge-integration model of object-based lightness computation that explains effects of spatial context and individual differences

Previous work has demonstrated that perceived surface reflectance (lightness) can be modeled in simple contexts in a quantitatively exact way by assuming that the visual system first extracts information about local, directed steps in log luminance, then spatially integrates these steps along paths through the image to compute lightness (Rudd and Zemach, 2004, 2005, 2007). This method of comput...
