ABSTRACT:
A system for classifying a two-dimensional object, the object having a boundary. The system includes a sensor for sensing the boundary of the object, a processor which assigns a chain code to the boundary of the object and memory for storing a plurality of chain code histograms corresponding to known two-dimensional objects. A histogram is generated from the object's assigned chain code and correlated in the processor with a chain code histogram from memory. A final ambiguity between the normalized chain code of the object and the chain code of the correlating known object is resolved through application of a Viterbi algorithm.
