A syntax-aided recognition scheme for handprinted english letters

摘要

Within the descriptive approach to pattern analysis and recognition, this paper argues for the need to distinguish between syntax-controlled and syntax-aided recognition schemes. The fundamental importance of recognition schemes based on syntax-aided learning is discussed. The main part of the paper describes some exploratory work undertaken to study operationally viable structures for syntax-aided learning in the context of handprinted letter recognition. The results of two experiments in recognition performed, using a syntax-aided (nonlearning) scheme. are given. Specific studies in learning suggested by this recognition scheme are discussed.
