The paper introduces a high-frame-rate and high-resolution image acquisition system with DVI Interface, which uses the CMOS image sensor of 2.3 million pixels as the light-sensitive chip and a high-performance FPGA as the main processor. In order to get better image quality and correct the unrealistic color, the image preprocessing is implemented based on FPGA, including color space conversion ...

OBJECTIVES The purpose of this study was to assess the prevalence and distribution of oral mucosal lesions in a Turkish adult population. MATERIAL AND METHODS Five thousand consecutive patients were examined during routine dental treatment. Some of the mucosal changes were diagnosed solely by clinical examination. When clinical features were not diagnostic, a biopsy was undertaken. Chi-square...

The objectives of this study were to investigate color patterns of shell and mantle edge pigmentation of a Pacific oyster, C. gigas, and to estimate variance components of the two colors. A sample of 240 F0 oysters was collected from six aquaculture farms in Tongyeong, Korea to measure shell color and mantle edge pigmentation. Among the F0s, male and female individuals with black (white) shell ...

This paper introduces a new color model, RBW, which can be used as an intuitive user-interface for selecting colors in computer graphics systems. It is based on the red-green, blue-yellow, and white-black color axes. These axes are similar to the axes in opponent color theory, but their semantics are different: in the RBW model, the white-black axis mixes white or black into the color rather th...

This paper presents an eye detection technique basedon color and shape features. The approach consists of three steps: a rough eye localization using projection technique, a white color thresholding to extract white sclera, and an ellipse fitting to fit the ellipse shape of eye. The proposed white color thresholding utilizes the normalized RGB chromaticty diagram, where white color objects are ...

In this study some properties ofthe methanol-water mixture such as diffusivity, density, viscosity, and hydrogen bonding were calculated at different temperatures and <span style="font-size: 10pt; colo...

One of the methods for creating white light with light-emitting diodes (LEDs) is mixing radiations from several different colored LEDs. Mixed-color LEDs are expected to have greater luminous efficacy because they do not undergo downconversion losses like phosphor-converted white LEDs. However, in reality mixed-color LED systems require extra optical elements to reduce spatial color variation an...

Meat color is considered to be the most important indicator of meat quality, however, the molecular mechanisms underlying traits related to meat color remain mostly unknown. In this study, to elucidate the molecular basis of meat color, we constructed six cDNA libraries from biceps femoris (Bf) and soleus (Sol), which exhibit obvious differences in meat color, and analyzed the whole-transcripto...

The absolute visual magnitude as function of the observed color (B-V) , also named Hertzsprung-Russell diagram can be described through five equations; that in presence of calibrated stars means eight constants. The developed framework allows to deduce the remaining physical parameters that are mass , radius and luminosity. This new technique is applied to the first 10 PC , the first 50 pc , th...
