A mathematical modeling approach to size invariant Greek character recognition

A new approach to the automatic machine recognition of Greek characters of any size and font is presented. Unlike most of the traditional methods, which are based on syntactic schemes, this method utilizes the topological characteristics of the characters to achieve recognition. Each character is individually modeled to a standard geometrical shape, and the least mean square method is used to form the best fit. Sample characters like alpha, beta, gamma, omega, theta, omicron, and rho have been successfully modeled with standard geometrical shapes, such as circles, lemniscates, cardioids, ellipses, and lines. An alternate approach to the automatic and reliable recognition of handwritten and printed Greek characters is also discussed
