function [a,map] = rgb2ind(r,g,b,cm,dith) %RGB2IND Convert RGB image to indexed image. % RGB2IND converts RGB images to indexed images using one of % four different methods: direct translation,

function rgb = ycbcr2rgb(in) %YCBCR2RGB Convert YCBCR values to RGB color space. % RGBMAP = YCBCR2RGB(YCBCRMAP) converts the YCBCR values in the % colormap YCBCRMAP to the RGB color space. If Y

function y = isrgb(x) %ISRGB Return true for RGB image. % FLAG = ISRGB(A) returns 1 if A is an RGB truecolor image and % 0 otherwise. % % ISRGB uses these criteria to determine if A is an R

function out = rgb2ycbcr(in) %RGB2YCBCR Convert RGB values to YCBCR color space. % YCBCRMAP = RGB2YCBCR(RGBMAP) converts the RGB values in RGBMAP to % the YCBCR color space. YCBCRMAP is a M-by

function [y,i,q] = rgb2ntsc(r,g,b) %RGB2NTSC Convert RGB values to NTSC colorspace. % YIQMAP = RGB2NTSC(RGBMAP) converts the M-by-3 RGB values in % RGBMAP to NTSC colorspace. YIQMAP is an M-by-

function [rout,g,b] = ind2rgb(a,cm) %IND2RGB Convert indexed image to RGB image. % RGB = IND2RGB(X,MAP) converts the matrix X and corresponding % colormap MAP to RGB (truecolor) format. % %
