I'm computing the "sliding" (lags only in one dimension) cross correlation of spectrograms. For many cases, the spectrograms are quite large and the needed lag ranges are small. These are used as a sound similarity metric and as a method to estimate time delays (though I favor xcorrs of the actual signals for TDE, others have used spectrogram cross correlation so I need to do the same for comparison).
Now that you mention it, normalizing xcorr2 results myself probably wouldn't be very difficult. I'll take a look at what it is actually doing and see if that makes sense. If that is all there is to it, then shouldn't implementing normxcorr2 should be very simple? -- Travis ------------------------------------------------------------------------------ Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects _______________________________________________ Octave-dev mailing list Octave-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/octave-dev
