colour maps - Arvind Raman - Jun 19 8:19:00 2001

Hi, I would like to know how one should create a colour map. Is there any site which suggests how to do so or lets you download the colour map table. Thanks and regards Arvind __________________________________________________ |

Hi Arvind, u can create a color map for any image by creating a table with the color values (RGB or gray) in each row, and replace the pixel value in the image grid with the row number (index) of the corresponding pixel color.. The type of images are called indexed images. If u have access to Matlab, read the manual for Image Processing Toolbox.. This is generally used to save space in storing the image pixel values directly and also sometimes for color quantization.

You cannot download the any "colormap" for any image. --vinod |
