Hi Ibai,
ShapeLogic is a plugin for declarative / rule based programming under
ImageJ. As a proof of concept it has a rudimentary OCR example,
showing that you can define letters with simple rules. It will read
the letters in the sequence of a scan line so they will not come in
the right order. ShapeLogic might serve as a good starting point if
you are looking to program your own OCR system. ShapeLogic is under
the very unconstrained MIT license.
Here is the set of rules that is defining the letter C:
rule("C", HOLE_COUNT, "==", 0., letterFilter);
rule("C", T_JUNCTION_POINT_COUNT, "==",0., letterFilter);
rule("C", END_POINT_BOTTOM_POINT_COUNT, "==", 1., letterFilter);
rule("C", MULTI_LINE_COUNT, "==", 1., letterFilter);
rule("C", VERTICAL_LINE_COUNT, "==", 0., letterFilter);
rule("C", END_POINT_COUNT, "==", 2., letterFilter);
rule("C", INFLECTION_POINT_COUNT, "==", 0., letterFilter);
rule("C", CURVE_ARCH_COUNT, ">",1., letterFilter);
rule("C", HARD_CORNER_COUNT, "==", 0., letterFilter);
rule("C", SOFT_POINT_COUNT, ">", 0., letterFilter);
