BACKGROUND AND PURPOSE Transcranial color-coded duplex sonography has become a standard diagnostic technique to assess the intracranial arterial status in acute stroke. It is increasingly used for the evaluation of prognosis and the success of revascularization in multicenter trials. The aim of this international consensus procedure was to develop recommendations on the methodology and document...

OBJECTIVE To determine if power Doppler ultrasound examination of the endometrium can contribute to a correct diagnosis of endometrial malignancy in women with postmenopausal bleeding and endometrium > or = 5 mm. METHODS Eighty-three women with postmenopausal bleeding and endometrium > or = 5 mm underwent gray-scale and power Doppler ultrasound examination using predetermined, standardized se...

Most digital color cameras are based on a single CCD or CMOS sensor combined with a color filter array (CFA): each pixel measures only one of the RGB colors. The most popular CFA is the Bayer CFA (Bayer, 1976) shown in fig. 1. Demosaicking algorithms interpolate the sparsely sampled color information to obtain a full resolution image, i.e. three color values per pixel. Many demosaicking algorit...

Abstract In this paper, we found 2939 S-type stars from LAMOST Data Release 10 using two machine-learning methods, and 2306 of them were reported for the first time. The main purpose work is to study how divide into intrinsic extrinsic with photometric data spectra. Using infrared data, adopted methods distinguish stars, i.e., XGBoost algorithm color–color diagrams. We trained model 15 input fe...

Introduction: Thyroid nodules are commonly encountered on ultrasonographic studies. Color doppler ultrasonography can be utilized to help in differentiating malignant and nonmalignant nodules based on different imaging criteria. Objective: The objective of this study is to correlate sonographic and color Doppler characteristics of thyroid nodules with the results of sonographically guided fine-...

Purpose: To determine the reliability of TwoDocs computerized test for the evaluation of color vision and contrast sensitivity in normal adults. Methods: Thirty normal volunteers aged from 20 to 30 years (mean 23.3 years) had their color vision and contrast sensitivity tested by a new computerized test (TwoDocs test). Informed consent was obtained from all participants before testing. Inclusion...

Image quality assessment is a difficult and complex task. Quality attributes have been used in the evaluation of perceived image quality in an attempt to reduce the complexity and the dimensionality. Recently, Pedersen et al. (CIC, 2009) proposed a set of quality attributes for the evaluation of color prints. In this paper we perform an experimental validation of these quality attributes to ens...

BACKGROUND The ABCD (Asymmetry, Border, Color, and Dimension) criteria represent a commonly used clinical guide for the diagnosis of early melanoma. The authors revised these criteria in the light of objective measurements of the features of pigmented skin lesions obtained by telespectrophotometric analysis (TS) in the visible and near-infrared wavelengths. METHODS This study involves a conse...

Illumina Infinium DNA Methylation BeadChips represent the most widely used genome-scale DNA methylation assays. Existing strategies for masking Infinium probes overlapping repeats or single nucleotide polymorphisms (SNPs) are based largely on ad hoc assumptions and subjective criteria. In addition, the recently introduced MethylationEPIC (EPIC) array expands on the utility of this platform, but...

This article is about a visual investigation of paleochannel identification using ALOS 2 PALSAR (Advanced Land Observing Satellite Phased Array type L-band Synthetic Aperture Radar 2) radar satellite image. The image has higher layer-penetration ability than the optical so that characteristics near-surface materials are possible to be detected, including morphology abandoned river stream. purpo...
