The National Institute of Standards and Technology (NIST) has developed a standard reference form-based handprint recognition system for evaluating optical character recognition.NIST is making this recognition system freely available to the general public on CD-ROM.This is a source code distribution written primarily in C with two additional utitities having FORTRAN components.Library utihties are provided with the recognition system for con- ducting form registration, form removal, field isolation, field segmentation, character normalization, feature extraction, character classification, and dicticHiary-based posti)rocessing.A host of data structures and low-level utilities are also provided.These utilities include the application of spatial histograms, Least-Squares fitting, spatial zooming, connected components, Karhimen Loeve feature extraction, Probabihstic Neural Network classification, multiple-key sorting, dynamic string alignment, and dictionary matching.The recognition system has been successfully compiled and tested on a host of UNIX workstations including computers manufactured by Digital Equipment Corporation, Hewlett Packard, IBM, Silicon Graphics Incorporated, and Sun Microsystems.A CD-ROM can be obtained free of charge by sending a letter of request to NIST.This report documents the system in terms of its installation, organiza- tion, and functionality.
