"3d-iwt" appears to refer to 3D Integer Wavelet Transform.

When you say "don't know how to perform", I would see this question as "I have the code, but I can't run it". As there is no IWT command in MATLAB, you probably have it from a different source?

Or do you mean "I need to do something called 3d-iwt", but where do I get it?
