Classification: 382/203

Shape and form analysis:

(under subclass 195) Subject matter wherein the local features extracted for recognition processing include empirically derived character components (i.e., curves, bays, loops, convex arcs, etc.), geometrical configurations (i.e., rectangles, circles, triangles, parabolas, etc.), or

fundamental space measurements (i.e., distance, area, circumference, ratio of perimeter to area, etc.).
