While the Dollar Recognizer must search all training templates to recognize an unknown symbol, Quick$ employs hierarchical clustering along with branch and bound search to do this more efficiently. Experiments have demonstrated that Quick$ is almost always faster than the Dollar Recognizer and always selects the same best-match templates.Categories and Subject Descriptors (according to ACM CCS): I.7.5 [Computer Graphics]: Document Capture Graphics recognition and interpretation
