Book Review Recognition of Patterns, PETER W. BECKER. Polyteknisk Forlag, Kobenhaven, 1968. xiii+216 pp. (The book can be obtained by sending £1 or $2.50 to Munksgaard, Export Department, Noerregade 6, DK-1165, Copenhagen K, Denmark.) Tins book is a subsequent version of the author's doctoral thesis at the University of Denmark. The complete title should be "Recognition of patterns--using the frequencies of occurrence of binary words (FOBW)." FOBW, as developed by the author, is a new method for the design of pattern recognizers. Of central importance to the method is a non-exhaustive iterative procedure by which new, more effective pattern attributes can be generated from existing, less effective attributes. With this method, each pattern is first reduced to a binary sequence by a suitable coding method. Each sequence is then described in a statistical sense by the observed frequency of occurrence of certain selected binary words. The categorization of the patterns is performed on the basis of such observed values. Any pattern attribute used with this method is the observed frequency of occurrence of some specified binary word. The book contains seven chapters. The first chapter describes some basic concepts in the design of pattern recognizers and includes sections on areas of application, configuration of a pattern recognizer, factors that influence the design of a pattern recognizer, the selection of the attributes, decision procedures, indices of performance, and categorizer design. Chapter two is the main part of the book, and describes the FOBW method step by step. Chapters three to six are supplements to the steps described in Chapter two. Chapter seven is devoted to hardware implementation of the FOBW method. Two applications are given, the detection of jet engine malfunctions which are manifest in the engine sound, and the recognition of the ten spoken digits. In addition, more than 170 references are also listed; however, no subject index is included. Since this book is concerned with only one method of pattern recognition, it is recommended that it be used primarily as a reference. H. K. HUANG
