The image of a material's surface varies not only with viewing and illumination conditions, but also with the material's surface properties, including its 3-D texture and specularity. Previous studies on the visual perception of surface material have typically focused on single material properties, ignoring possible interactions. In this study, we used a conjoint-measurement design to determine...

The current global economy has increased international competition and the need to improve the quality of many manufactured products. Appearance measurements are used to determine the quality and acceptability of a variety of products from textiles to machine finishes. Since the manufacture and marketing of these products is international in scope, the methods, instruments, and standards for th...

the present study investigated the effect of marginal glosses (both l1 and l2) on incidental vocabulary learning of efl learners. the subject pool consisted of 154 third-semester iranian students enrolled at azad university, central branch. after administering a proficiency test, 90 homogeneous students were assigned to two experimental groups (x1 & x2) and one control group. afterwards, a 50 -...

The current study investigated the effects of L1 and L2 glosses on L2 vocabulary retention in incidental and intentional settings. To this end, 100 intermediate Iranian female learners of English as a foreign language at Soroosh High School were given a pre-test to make sure that they do not have any prior knowledge of the target words. Reading passages with three different glossing conditions ...

The measurement of specular gloss using a glossmeter is normalized in the ISO 2813 Standard, which widely used for many industrial applications. In practice, principle relies on primary standard that approximates perfectly polished back glass surface and an optical design where rectangular diaphragms are source detection apertures. Any deviation refractive index or polishing level artefact, mac...

Gloss is a property of paper that is used to emphasize print quality and color appearance. However, standard gloss measuring devices are not able to provide sufficiently accurate information to reliably develop papers with specific gloss characteristics. In this paper, the behavior of gloss is studied using goniometric imaging and spectral color information. A goniometric imaging system is prop...
