[Insight-users] Texture Filter

[Nicholas Tustison]

Hi Marsall,

Just in case you might be interested, another set of texture  
measurements based on run-length matrices is available via the  
following IJ publication

http://hdl.handle.net/1926/1374

The API of the corresponding classes is identical to that of the  
classes pointed out by Karthik so they should be relatively easy to  
use in addition to the cooccurrence-matrix-based classes.
