Hi Ignacio,

The command to run the letter recognizer example is:
Plugins>>ShapeLogic>>CapitalLettersMatch

It is described here: http://www.shapelogic.org/getting-started.html

CapitalLettersMatch is a macro.  The sequence of steps is:
* Turn image into binary
* Skeletonize
* Trace lines into polygons
* Analyze geometric features of polygons
* Match geometric features for each polygon against rules for letters
* Print a list of letters that has been matched to polygons

The 2 first steps are ImageJ commands, all the steps after is done by
a ShapeLogic plugin called: StreamVectorizer.java.

In ShapeLogic 1.4 I will add a command that writes out a simple report
of all the geometric features for all the polygons.  This should be a
minor change.  Let me know if you have any requests for what report
format would be useful, or if you have questions about how to modify
ShapeLogic yourself.

Yes ShapeLogic only works on 2D images.
