Abstract

A simple method to recognize the printed alphanumerics is discussed. The proposed method is a simple rule-based structural method to recognize printed alphanumerics of image scanner data based on the thinning operation. This paper also presents major achievement made toward the development of a fast hierarchical recognition scheme for the printed and handwritten facsimile data. The conventional thinning techniques give good results for high-resolution image scanner data, but they suffer drawbacks for low-resolution data. Our scheme recognizes 55 characters per second on the IBM PC/386 environment and the recognition rate is 98%.
