Hi I would like to develop a CDF 5/3 (LeGall 5/3) lifting wavelet in an FPGA so that I can do some image processing. Reading through some papers I have found the algorithm to code but I would like to perform the same thing in Matlab so that I can check my results. Can someone who knows about the wavelet toolbox tell me the required commands, so that I can enter a sequence of values and get the results. I am just interested in a 1D result to start. Thanks Jon

If you start Matlab, then type "HELP WAVELET", I think that the help documentation for "LWT" and "ILWT" under the title "LIFTING FUNCTIONS" might be of interest. Maurice Givens
