Abstract

Quantity is the integration of discretion and continuity. Starting with the definition of segment code, a basic data structure in which continuity is achieved through discrete series, this paper surveys a simple method by which arbitrary curve is represented by an integral series. Also, the application of four-vertex theorem and even number theorem of simple closed curve in pattern recognition is explained through the process of obtaining graphic characteristics of handwriting digits 0 - 9. Finally, the fundamental role of segment code in Pan-Euclidean geometry and the future of its development are discussed.
