Color Reduction in RGB based on Bacteria Foraging Optimization

RGB is called the additive model in which each color appear as the combination of primary colors; red, green and blue. The RGB color model is additive in the sense that the three light beams are added together, and their light spectra add, wavelength for wavelength, to make the final color's spectrum. To generate any color within the RGB color cube, all three RGB components need to be of equal pixel depth and display resolution. Also, any modification of the image requires modification of all three planes. Black color is the resultant of zero intensity for each component and full intensity for each component gives white. When the intensities for all the components are the same, the result is a shade of gray, darker or lighter depending on the intensity. When the intensities are different, the result is a colorized hue, more or less saturated depending on the difference of the strongest and weakest of the intensities of the primary colors employed. The present paper review the process of color reduction in RGBs based Bacteria Foraging Optimization.
