Hello Zag and Ignacio,

Weka surely works, but can it be applied to 3D images using 3D features? If yes, that would be great for other purposes, too.

I often separate weft yarns from warp yarns by calculating local orientation using, e.g., the structure tensor method. Thresholding based on orientation separates the yarns very effectively.
