Image quantization and digital halftoning are fundamental problems in computer graphics, which arise when displaying high-color images on non-truecolor devices. Both steps are generally performed sequentially and, in most cases, independent of each other. Color quantization with a pixel-wise defined distortion measure and the dithering process with its local neighborhood optimize different qual...

Endoscopy has been widely used in diagnosing gastrointestinal mucosal lesions. However, there are still lack of objective endoscopic criteria. Linked color imaging (LCI) is newly developed endoscopic technique which enhances color contrast. Thus, we investigated the clinical application of LCI and further analyzed pixel brightness for RGB color model. All the lesions were observed by white ligh...

Sodium bentonite can bind to dietary pigment and decreases yolk color scale. Sodium bentonite is one of the main parts of Formycine® Gold, the effect of different levels of Formycine® Gold and dietary pigment on egg quality, egg yolk color and performance criteria of laying hens from 26 to 34 week of age were studied. One hundred ninety two Hy-Line hens were divided into 24 groups of 8 birds ea...

The Uster ® High Volume Instrument (HVI ®) is used in the U.S. to classify cotton, including cotton color. The cotton color parameters measured on the HVI are Rd (diffuse reflectance) and +b (yellow-ness). Comments from industry have indicated that some cotton bales appeared to have changed significantly in +b (yellowness) from their initial HVI color measurements. As a result of these reports,...

Palm sugar is a product made from the sap of lontar tree flowers. Palmira Indonesia has started to develop palm products in form powder and drinks. The addition lemongrass stalks can be used as an alternative improve characteristics. This study aims determine effect adding obtain sensory characteristics herbal drink. research was conducted using completely randomized experimental design with pr...

desertification in arid, semi-arid and dry sub-humid regions is a global environmental problem. considering theincreasing importance of desertification and its complexity, the necessity of giving attention to desertification criteria andindices is essential. models and methods such as medalus, unep-fao, and others have been proposed on local andnational scales. in this research, imdpa was selec...

image retrieval is an important research field which has received great attention in the last decades. in this paper, we present an approach for the image retrieval based on the combination of text-based and content-based features. for text-based features, keywords and for content-based features, color and texture features have been used. query in this system contains some keywords and an input...

Introduction: Keloid is a fibroproliferative tumor with excessive growth caused by an abnormality in the wound healing process. Several factors are contributing to development of keloid, such as genetics, local and systemic factors. can happen any skin color, but more common darker colors related melanocytes, melanin, or ?-MSH. Color bar tool objective economical used determine each color. This...

Two ICC profi les were generated from an Epson ink jet printer under two printer conditions, default and 0% dot gain. Color matching experiments were performed by means of the “B-to-A” analysis with a set of CIELAB values which are reproducible by the ink jet printer. CIE-based color difference, CIEDE2000, between the initial LAB values and its derived values was analyzed and compared between t...
