Color images reveal more meaningful information to the human observers rather than grayscale ones. Regardless of the advantages of the existing well-known objective image quality measures, one of the common and major limitations of these measures is that they evaluate the quality of grayscale images only and don’t make use of color information. In this paper we propose an improved method for im...

Background: Accurate clinical information provided on dermatopathology requisition forms is often very important to achieve correct diagnosis. We searched to evaluate the clinical information actually provided on the Dermatopathology requisition forms of melanocytic lesions submitted to our laboratory. Method: The provided clinical information and given microscopic diagnoses were recorded for m...

1 Many image display devices allow only a limited number of colors to be simultaneously displayed. Usually, this set of available colors, called a color palette, may be selected by a user from a wide variety of available colors. Such device restrictions make it particularly difficult to display natural color images since these images usually contain a wide range of colors which must then be qua...

We have recently had the opportunity to determine some visual functions of a unilaterally color-blind person, that is, one who demonstrates some form of color blindness in one eye and normal (trichromatic) vision in the other. The fact that a condition of unilateral color blindness can exist has been known since 1879.1 Cases of unilateral color blindness have been historically important, for it...

The purpose of this study was to assess the accuracy of parametric analysis of transvaginal contrast-enhanced ultrasound (TV-CEUS) for distinguishing benign versus malignant ovarian masses. A total of 48 ovarian masses (37 benign and 11 borderline/malignant) were examined with TV-CEUS (Definity; Lantheus, North Billerica, MA; Philips iU22; Philips Medical Systems, Bothell, WA). Parametric image...

We introduce a CW two-color Ti : sapphire laser for terahertz spectroscopic applications. The laser provides two parallel beams at independently tunable wavelengths allowing one to select a difference frequency in the range from below 20 GHz to 50 THz. The laser is pumped by a single 6-W pump beam in order to keep the setup as simple as possible. Under these conditions, output powers of 150 mW ...

BACKGROUND Systolic (Sa) and diastolic (Ea) myocardial velocities measured by tissue Doppler (TD) imaging (TDI) recently were shown to be decreased in subjects who have mutations causing hypertrophic cardiomyopathy (HCM) but who do not have left ventricular (LV) hypertrophy. By studying these subjects at a later date, we sought to determine whether TDI predicts the subsequent evolution of the H...

Methods: Eligibility criteria for CAPT required 10 or more large ( 125 μm) drusen in each eye. Readers graded baseline photographs from all participants and all follow-up photographs from 402 untreated eyes. Drusen and pigment characteristics were used to assign the AREDS scale score. Choroidal neovascularization was identified from fluorescein angiograms. Geographic atrophy involving the macul...

A new species of Moraceae is described, illustrated and compared to its close morphological relatives. Dorstenia triseriata presents similarities with Dorstenia turnerifolia but distinguished by size of peduncle, diameter of receptacle, number of bract rows, color of marginal bracts, and by an indistinct fringe on inflorescence. A conservation assessment based on IUCN criteria determines the ne...

The commercial value of ornamental fish is primarily dependent on their external body colouration. Fade coloured fish fails to attract the interest of the buyers. In the present study an experiment were conducted to evaluate the efficacy of four types of feed (Living tubifex, Dried tubifex, Dried Daphnia and Prepared granulated feed) in the rearing of fantail guppy. Carotenoid content of the fe...
