Natural-color Yellow Diamonds
widely encountered of the “fancy color” diamonds (figure 1). From 1998 to the present, GIA has issued grading reports on more than 100,000 yellow diamonds, by far the most common of the fancy-color diamonds submitted to our laboratory. In 2003, for example, 58% of the diamonds submitted for GIA Colored Diamond Grading Reports or Colored Diamond Identification and Origin of Color Reports were in...
متن کاملNatural scene text localization using edge color signature
Localizing text regions in images taken from natural scenes is one of the challenging problems dueto variations in font, size, color and orientation of text. In this paper, we introduce a new concept socalled Edge Color Signature for localizing text regions in an image. This method is able to localizeboth Farsi and English texts. In the proposed method rst a pyramid using diff...
متن کاملDyeing Properties and Color Fabrics Using Natural Dye and Mordant
An ecological approach has been obtained by using natural dyes and mordant for dyeing process. Fabrics dyed using myrobalan extract as natural mordants and green dye. A red color were obtained by using theses mordants. The color of dyed fabrics was investigated in CIELab L, a and b and K/S values. Finally, all dyed fabrics were tested for wash and light fastness properties as per ISO standard t...
متن کاملFrequently Asked Questions about Color
www.poynton.com [email protected] This FAQ is intended to clarify aspects of color that are important to color image coding, computer graphics, image processing, video, and the transfer of digital images to print. I assume that you are familiar with intensity, luminance (CIE Y), lightness (CIE L*), and the nonlinear relationship between CRT voltage and intensity (gamma). To learn more about t...
متن کاملColor signals in natural scenes: characteristics of reflectance spectra and effects of natural illuminants.
Multispectral images of natural scenes were collected from both forests and coral reefs to represent typical, complex scenes that might be viewed by modern animals. Both reflectance spectra and modeled visual color signals in these scenes were decorrelated spectrally by principal-component analysis. Nearly 98% of the variance of reflectance spectra and color signals can be described by the firs...
