Uniform Quantization on a Slice of the RGB Color Cube.
With minimum variance quantization, the color cube is cut up into boxes (not necessarily cubes) of different sizes; the sizes of the boxes depend on how the colors are distributed in the image.
Therefore, only one of the boxes is used to produce a color for the colormap.This example illustrates mapping two images to the same colormap.Edit- Paste as New.Colormap mapping (described in, colormap Mapping the quality of the resulting image depends on the approximation method you use, the range of colors in the input image, and whether or not you use dithering.With uniform quantization, the color cube is cut up into equal-sized boxes (smaller cubes).Colormap Mapping If you specify an actual colormap to use, rgb2ind uses colormap mapping (instead of quantization) to find the colors in the specified colormap that best match the colors in the RGB image.Quantization involves dividing the RGB color cube into a number of smaller boxes, and then mapping all colors that fall within each box to the color value at the center of that box.Once the image is divided into n optimally located boxes, the pixels within each box are mapped to the pixel value at the center of the box, as in uniform quantization.The allowable range for a tolerance setting is 0,1.Offon, smooth px, amount, type, type, a:Number of Each Color in rgbb:Number of Colors.Rgb2ind supports two quantization methods: uniform quantization and minimum variance quantization.The number you specify determines the number of boxes into which the RGB color cube is divided.
