Progress report on pattern recognition

Abstract: A survey of the field of pattern recognition is presented in a manner broad enough not to be limited to the progress in recent years alone. In this review the emphasis is on the principal problems, methods and applications, and hence the omission of many details is unavoidable. Pattern recognition is discussed both intuitively and, more formally, as a many-to-one mapping. Several sources of variability, leading to many different possible representations of a certain pattern, are mentioned. All of these representations have to be classified as one pattern indicated by a certain class. An essential aspect of pattern recognition, relevant for this classification, is the selection of features by means of preprocessing the input data. Another essential aspect is the decision process based upon these features and leading to the classification. Several types of preprocessing are treated. Global and local transformations suitable for different types of filtering, decomposition and segmentation are indicated. A discussion of the three techniques used in pattern recognition, namely statistical, fuzzy and linguistic, is given.
