Bhat presents a system for distinguishing between text and shape strokes based on the entropy of the strokes. Strokes are translated into a string of characters representing which angle the stroke is pointed. Letters are added as the stroke changes direction, and also special markers for the endpoints. Then, a simple definition of zero-order entropy is used with those strings. Bhat also uses the gzip library to provide a higher-order definition of entropy.
Bhat further improves on the accuracy of the Patel et al. system from Reading #13.
