Journal ArticleDOI
Thinning methodologies-a comprehensive survey
TL;DR: A comprehensive survey of thinning methodologies, including iterative deletion of pixels and nonpixel-based methods, is presented and the relationships among them are explored.
Journal ArticleDOI
Computer recognition of unconstrained handwritten numerals
TL;DR: It is shown that it is possible to reduce the substitution rate to a desired level while maintaining a fairly high recognition rate in the classification of totally unconstrained handwritten ZIP code numerals.
Journal ArticleDOI
Optimal combinations of pattern classifiers
Louisa Lam,Ching Y. Suen +1 more
TL;DR: A Bayesian formulation and a weighted majority vote (with weights obtained through a genetic algorithm) are implemented, and the combined performances of 7 classifiers on a large set of handwritten numerals are analyzed.
Book ChapterDOI
Classifier Combinations: Implementations and Theoretical Issues
Louisa Lam,Louisa Lam +1 more
TL;DR: Some of the current developments according to the structure of the combination process are considered, and some issues involved in each structure are discussed.
Journal ArticleDOI
Structural classification and relaxation matching of totally unconstrained handwritten zip-code numbers
Louisa Lam,Ching Y. Suen +1 more
TL;DR: A system for recognizing totally unconstrained handwritten numerals is described, which comprises a feature extractor and two classification algorithms that identify the majority of the samples and a robust relaxation algorithm which classifies the rest of the data.
