Recent progress to formal approach of pattern recognition and scene analysis

摘要

The P.R. techniques and programs may currently be considered as a “bag of tricks”, justified by their experimental results. Formalization and theory have been lagging. Propositions are made for a formal P.R. language, similar to the language of logic, which could be used to describe precisely the P.R. algorithms. Interpretations of the terms of this language have to be made in other languages: natural, machine or programming languages. A P.R. function should be constructive, i.e. find its interpretation in an algorithm or program. A training set is far from enough to define such a function. Properties of the experimental domain should guide the P.R. specialist. They are examined and discussed, in an effort to find some unity in the P.R. techniques.
