Control strategies in pattern analysis

摘要

A survey is made on the control strategies in pattern analysis. Discussions are made on the problems of (1) combinatorial and sequential methods, (2) bottom-up and top-down processes, (3) feedback processes, (4) procedural and declarative methods, (5) use of knowledge, and (6) recursive analysis processes. Merits and demerits are pointed out contrastively in and among these methods, with the author's personal research results. The importance of the declarative method in pattern analysis, especially in the patterns of complex objects, is stressed. The importance of the feedback and recursive applications of analysis algorithms is also mentioned to obtain the accurate results.
