TOPIC: Pulmonary Vascular Disease TYPE: Original Investigations PURPOSE: Lab values are essential sets of parameters for the prognosis patients with pulmonary arterial hypertension (PAH). METHODS: We analyzed lab variables obtained at baseline in 7 PAH clinical trials: SERAPHIN, BREATHE, CHEST-2, PATENT-2, FREEDOM, TRIUMPH, and subcutaneous treprostinil study. The outcome analysis was mortality...

Abstract The aim of the research was to compare possibility distinguishing cultivars processed beetroots using image analysis technique and sensory evaluation. differentiation samples tested for freeze-dried beetroot ‘Czerwona Kula’ ‘Cylindra’, lacto-fermented ‘Cylindra’. textures from images quarters root slices, as well attributes evaluated by expert assessors, were determined. differences in...

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...

To reproduce an image, it is necessary to map out of gamut colors of the image to destination gamut. It is clear that the best color gamut mapping introduces the perceptually closest image to the original one. In this study, a new color gamut mapping is purposed by the aid of Genetic Algorithm (GA). The color difference between the original and mapped images based on S-LAB formula was chosen as...

Abstract As a widely consumed fermented milk product, yogurt undergoes constant development to increase its functional properties. Monascus purpureus -fermented durian seed, which has been proven possess antioxidative properties, the potential improve This study aimed analyze use of seed (MFDS) as ingredient in and effect on physicochemical lactic acid bacteria (LAB) count, consumer acceptabili...

We propose an automatic content-based image recognition technique in this paper using color features. Our intention is to cluster a set of digital images in several categories on the color similarity basis. The images are processed using LAB color space in the feature extraction stage. The resulted color-based feature vectors are clustered using an automatic unsupervised classification algorith...

INTRODUCTION Standardization and validation of the color displayed by digital slides is an important aspect of digital pathology implementation. While the most common reason for color variation is the variance in the protocols and practices in the histology lab, the color displayed can also be affected by variation in capture parameters (for example, illumination and filters), image processing ...

The aim of this study was to evaluate the discoloration effects of water, cola-based soft drink, coffee, and wine on resin composites used in restorative dentistry and the possibility of removing the stain with chair side manual polishing. The A2 shade of three materials was tested. Disc specimens were prepared. A spectrophotometer was used to measure the baseline CIE-Lab color parameters of ea...

In this paper, we developed a novel approach that provides effective and robust segmentation of color images. It preprocesses an image by converting color information from RGB to CIE L*a*b* color spaces that CIE L*a*b* color spaces can express color in a device-independent way. CIE L*a*b* color space is better suited to digital image manipulations than the RGB space, because it had removed corr...

Color quantization is an important part of image processing, image formation, and related research. This paper presents a novel color image quantization algorithm which addresses the question of how to incorporate principles of human perception of color variation into the process of quantization. The color variation measure, calculated first in CIE Lab color space, is used to evaluate color var...
