While much attention has been given to understanding biases in gloss perception (e.g., changes perceived reflectance as a function of lighting, shape, viewpoint, and other factors), here we investigated sensitivity surface reflectance. We tested how visual differences specular varies the magnitude Stimuli consisted renderings glossy objects under natural illumination. Using maximum likelihood d...

To investigate the effects of different glossing conventions on vocabulary recognition and recall, 158 participants were given a pre-test to make sure that they did not have any prior knowledge of the target words. Reading passages with four different glossing conventions (interlinear, marginal, pre-text, and post-text) were given to eight groups. Four groups received interlingual glosses and f...

A high spatial resolution imaging colorimeter and glossmeter is presented. The combination of a high quality imaging colorimeter with an off axis imaging optics and a highly stabilized RGB LED source allows color and gloss measurements of small parts with high accuracy. The characteristics of the system with some experimental results on black coated and printed papers are presented. Introductio...

THE composite character of the two chapters--Leviticus 13 and 14--comprising the laws and regulations for the diagnosis and treatment of various skin diseases, and of suspicious spots appearing in garments and houses, together with the purification rites, has long been recognized. Indeed, the mere enumeration of the variety of subjects treated of in these two chapters, which form a little code ...

What is the relation between the material, conventional symbol structures that we encounter in the spoken and written word, and human thought? A common assumption, that structures a wide variety of otherwise competing views, is that the way in which 10 these material, conventional symbol-structures do their work is by being translated into some kind of content-matching inner code. One alternati...

Software maintenance is a major source of expense in software projects. A proper evolution process is a critical ingredient in the cost-efficient development of high-quality software. A special case of software evolution is refactoring that cannot change the external behaviour of the software system yet should improve the internal structure of the code. Hence, there is always a need to verify a...

A simplicial complex L on n vertices determines a subcomplex TL of the ntorus, with fundamental group the right-angled Artin groupGL. Given an epimorphism χ : GL → Z, let T L be the corresponding cover, with fundamental group the Artin kernel Nχ. We compute the cohomology jumping loci of the toric complex TL, as well as the homology groups of T L with coefficients in a field k, viewed as module...

Predicting the final appearance of a print is crucial in graphic industry. The aim this work to build mathematical model predict visual gloss 2D printed samples. We conducted psychophysical experiment where observers judged samples with different colours and values. For experiment, new reference scale was built. Using results from prediction for assessment has been developed. By using Principal...

In this study, we investigated the color, gloss and surface roughness of bamboo (Phyllostachys bambusoides) and Scots pine (Pinus sylvestris) samples impregnated with boron and copper based preservatives during accelerated weathering from 168 h to 672 h. Tanalith-E, ACQ, wolmanit-CB were used as copper-based chemicals, while a mixture of boric acid and borax (7:3; w/w) was used as the boron com...

Computer simulated stimuli can provide a flexible method for creating artificial scenes in the study of visual perception of material surface properties. Previous work based on this approach reported that the properties of surface roughness and glossiness are mutually interdependent and therefore, perception of one affects the perception of the other. In this case roughness was limited to a sur...
