This paper presents a new measure of semantic relatedness between concepts that is based on the number of shared words (overlaps) in their definitions (glosses). This measure is unique in that it extends the glosses of the concepts under consideration to include the glosses of other concepts to which they are related according to a given concept hierarchy. We show that this new measure reasonab...

Interactions between the albedo and the gloss on a surface are commonplace. Darker surfaces are perceived glossier (contrast gloss) than lighter surfaces and darker backgrounds can enhance perceived lightness of surfaces. We used maximum likelihood conjoint measurements to simultaneously quantify the strength of those effects. We quantified the extent to which albedo can influence perceived glo...

Wood finishes protect the surface of wood from external agents, enhance its looks and improve its gloss (luster). On constant external exposure, UV rays gradually degrade the film coating resulting in loss of gloss. In this study, two commonly used finishes namely spirit shellac and polyurethane finish were used to investigate the pattern of loss of gloss due to UV interference. Two coatings of...

AIM The aim of this study was to investigate the association of different degradations on the roughness, gloss, and color changes of microhybrid composites. MATERIALS AND METHODS Ten specimens were prepared for Charisma, Amelogen Plus, Point 4, and Opallis resins. Surfaces were polished and baseline measurements of roughness, gloss, and color were recorded. Specimens were then submitted to ch...

It is currently debated whether the perception of gloss is linked to the statistical parameters of the retinal image. In particular, it has been suggested that gloss is highly correlated with the skewness of the luminance histogram. However, other psychophysical work with artificial stimuli has shown that skewness alone is not enough to induce the perception of gloss. Here, we analyzed many ima...

The purpose of this study was to evaluate the effect of aging protocols on surface gloss of composites. Cylindrical resin composite specimens (6 mm in diameter, 1 mm thick) were fabricated and divided into three groups (N = 60): microfilled (MiFi), nanohybrid (NaHy), and nanofilled (NaFi). Specimens were distributed into four aging subgroups: thermocycling (5° to 55°C, 15,000 cycles); ethanol i...

This paper describes how SMIL can be extended to support 3D audio in a similar fashion than AABIFS does it for MPEG-4. The SMIL layout is extended with an extra dimension to support a 3D space. Then, audio elements are positioned in the 3D space, whilst a listener element defines a listening point. Similarly to AABIFS perceptual modeling approach, an environment element describes environmental ...

The aim of this study was to assess gloss of tooth by digital photography. A gonio-imaging system (gonio being Greek for angle) was developed to measure the gloss of human teeth in a laboratorial stage. Polarised and non -polarised images were acquired around the specular angle. The gloss component was extracted and normalised to a theoretical standard; a BRDF curve was built to describe the gl...

The chemical durability of three types of optical glass (BSC 517, BaC 572, and F 620) and chemical Pyrex llave been studied o\"er an extended pH range by means of an interfe rometer proced ure. The accompanying effect on the appearance (gloss retained) and on the transmittance of the specimens has also been determ ined. The results illustrate the con fu sion t ll at might a rise from choosin g ...

The perceptual gloss space defined in Pellacini et al. [9] could be used for quality control applications to bring similar benefits as seen in color with the use of CIELAB. However, a distance metric to relate all the dimensions in the space does not exist, and the space was only validated with the materials used to define the space. The current space’s distance metric does not allow relating d...
