The National Institute of Standards and Technology (NIST) has developed a form-based handprint recognition system for reading information written on forms. This public domain software test-bed may be obtained from NIST free of charge on CD-ROM. The recognition system is modular in design and integrates algorithms from heterogeneous computational paradigms including artificial intelligence, image processing, robust statistics, and pattern recognition. At the core of the system are some 15 libraries containing more than 725 subroutines and 39,000 lines of program code that together define an Application Program Interface (API). Algorithms are provided for conducting generalized form registration, intelligent form removal, adaptive character segmentation, neural network-based classification, and lexical postprocessing. To support these tasks, a host of data structures and interdisciplinary technologies are utilized, including affine image transformations, image morphology, connected imag...
