function [r,g,b] = ntsc2rgb(y,i,q) %NTSC2RGB Convert NTSC values to RGB color space. % RGBMAP = NTSC2RGB(YIQMAP) converts the M-by-3 NTSC % (television) values in the colormap YIQMAP to RGB col

function a = rgb2gray(r,g,b) %RGB2GRAY Convert RGB image or colormap to grayscale. % RGB2GRAY converts RGB images to grayscale by eliminating the % hue and saturation information while retainin
