Wavelets

Started by maxascent August 12, 2010
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

I'm not sure what exactly you're asking, but I assume you want something with which to compare the output of your algorithm. 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

Maurice Do you happen to know what the settings I would use for the LeGall 53 when using the lwt function? Thanks Jon
