Handprinted Character Recognition

Abstract : This report discusses a research effort whose object is the design of a handprint alpha-numeric reader capable of human recognition rates. The effort included: Collection of a large data base of unconstrained handprinted alpha-numeric characters; Editing the data to re- label mislabeled characters, remove noise, and delete totally illegible characters. A separate programming package (the Data Base Editing Package) was designed and implemented for this purpose; The design of new features to improve the performance of the system; The design of the recognition logic using an OLPARS-like program, the Alpha-Numeric Logic Package (ANLP), which used the expanded feature set; An independent test of the logic using a set of 6127 characters not included in the design set; and, Analysis of the results of the independent test to develop reject strategies to reduce substitution errors.
