I need some help from anyone using The Wavelet Explorer Package. I want to analyze images using the Wavelet Packet Transform instead of the much simpler and really not so useful Wavelet Transform. What confuses me, however, is the amount of information that comes out of it and I just dont know how to deal with it. For example, if I use the Wavelet Transform and then do Dimensions/@wtdata and get an output something like {{16,32},{3,16,32},{3,32,64},....etc}} I know how to deal with that so that I can look at each of the individual results. But when I apply the same to the WPT and get something like {{2,2,2...} then I'm completely lost. The way I eventually want to use the results of the WPT are to either use THRESHOLDING or to simply set various coefficients to 0. Can someone tell me how to deal with the WPT output in some kind of straight forward manner? thanks. Jerry Blimbaum NSWC Panama City, Florida
