Hi,

First, I want to mention that I'm not in an attempt of doing a homework from my question here :-)

If I was required to *quantize* the colour planes of an image using 4-bits:

- What does this statement mean?

- How can I perform this in matlab?

Thanks.

Type ver on the command line to find out what toolboxes you have installed. Tell us what it says (you don't need to tell us your license number though).

Note: "ver" tells what is installed, not what is licensed.
