ABSTRACT

The syntactic method uses structural information to define and classify patterns. Syntactic methods have been applied to the general problem of scene analysis, e.g., to the automatic recognition of chromosomes and finger prints. The syntactic approach has gained a lot of attention from researchers in the field of scene analysis since this approach possesses the structure-handling capability which seems to be important in analyzing patterns and scenes. The syntactic approach is also known by the terms linguistic, structural, and grammatical approach. The basic ideas behind the syntactic approach are similar in principal to those of the decision-theoretic approach. In most applications of syntactic signal processsing, a class of signals is given and a recognizer has to be designed to recognize the class of signals of interest. Several syntactic algorithms have been suggested for the analysis of the Electrocardiograms signal, especially for the problem of QRS complex detection.
