STATEMENT OF PROBLEM Although all-ceramic restorations are widely used, there is a lack of information on how color is affected by fabrication procedures. Color matching problems may be encountered in a definitive restoration despite careful shade selection. PURPOSE The aim of this study was to evaluate the effect of dentin ceramic thickness and repeated firings on the color of glass-infiltra...

abstract this study was carried out in japan for evaluation of the relationship between phenolic compounds and skin color indices of 3 apples cultivars including ‘fuji’, ‘jonathan’ and ‘jonagold’, in 2006. in ‘jonathan’, l* (lightness) increased with decreasing red color of skin. in ‘jonagold’, chroma increased with increasing red color. but in ‘fuji’, there was no detectable difference between...

Color correction is an image-altering technique that modifies image color in such a way it matches reference image. Many approaches have already been proposed by various researchers; however, those models unable to reduce errors between two images, which results inefficiency and poor-quality images. This research paper presents effective improved model wherein alternate least square (ALS) root ...

some physicochemical parameters of honey have been introduced by the international honey commission to evaluate its quality and origin but processes such as heating and filtering can affect these parameters. in traditional iranian medicine, deslagging process involves boiling honey in an equal volume of water and removing the slag formed during process. the aim of this study was to determine th...

OBJECTIVES This study aimed to evaluate the effects of chlorhexidine mouthrinses on color stability of nanofilled and micro-hybrid resin-based composites. MATERIALS AND METHODS In this in-vitro study, 160 disc-shaped specimens (7x2mm) were fabricated of Filtek Z250 and Filtek Z350XT Enamel (A2 shade). The samples of each group were randomly divided into eight subgroups (n=10). The specimens w...

In this paper a new quantitative tissue characterization (QTC) program was developed for computing a standardized sets of parameters and quantitative color-mapping of these parameters for non-invasive accurate diagnosis of liver pathologies. In this program, histogram, co-occurrence matrix, runlength matrix, gradient texture feature coding, backscattering, attenuation and speckle parameters wer...

An extensive grid of metal-rich isochrones utilizing the latest available input physics has been calculated for comparison with the old, metal-rich open cluster NGC6791. The isochrones have been simultaneously fit to BV and VI color magnitude diagrams, with the same composition, reddening and distance modulus required for both colors. Our best fitting isochrone assumes [Fe/H] = +0.4, scaled sol...

The system uses the OpenMV algorithm module combined with k-means framework through Euclidean distance formula to facilitate automation of logistics sorting, which identifies color parcels in LAB space. It sends identified information motion drive module, sorts and transports designated storage area. fusion algorithms allows identify colors transportation accurately.

Exploring the Solar System is a science enrichment program taught at LPI for gifted fifth-grade students [1]. As part of this semester-long course, we teach a series of three computer labs on digital image processing. Images of the planets obtained by various NASA spacecraft have had a key role in the overall exploration of the Solar System. The purpose of these labs is to teach the students th...
