Industrial Automatic Control Systems and Controllers Annotation << Back IImage Model Represented by Wavelength Values of Continuous Visible Radiation Spectrum Radaev S.V. The paper analyzes various methods of RGB code transformation to wavelength values and offers an alternative techniques for RGB code transformation to wavelength values of the visible radiation spectrum. It notes that the sequence of colors represented by RGB codes differs from the color sequence of the visible spectrum. This fact is caused by RGB code formation principle and the specificity of the human vision as well. Key properties of the mathematical XYZ color model are analyzed with the objective to reveal its specific features in various color ranges. The results presented are based on Matlab 7.10.0 (R2010a) modeling. Keywords: digital image, wavelength, color tone, visibility curve, color coefficients, purple colors, complementary colors.
