Anybody aware of IDL routines on wavelet analysis for image texture segmentation ? I'd be very gratefull ! -- ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½ Tom Wassenaar INRA Science du Sol, 2 place Pierre Viala 34060 Montpellier Cedex 02, tel. +33 (0)499612764 Mï¿½l : wassenaar@ensam.inra.fr ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ï¿½ ï¿½ï¿½ï¿½
Try the IDL Wavelet Workbench, available from RSI's ftp site (ftp.rsinc.com, under /pub/user_contrib/wwb). There's more info about it at http://www.amara.com/wwbdev/wwbftp.txt. I've found it to be quite useful and well-written, although I've had to extend it some myself for some functions to work in 2D.

IDL5.3beta appears to have additional wavelet functions as an add-on, altho there is no promise that what is in a beta will go commercial. It would be worth contacting RSI and see if they can help.
