MATLAB Programming/Image Processing Toolbox - Wikibooks, open books for an open world A note on color space conversions [edit] Note that when converting from device-specific color spaces like RGB to non-device-specific spaces like LAB or XYZ, some inaccuracy will inevitably arise. One reason for this is that RGB values as given by MATLAB a
