ICR: A Transputer-Based Intelligent Character Reader

Authors: Wong F.S., Francis, Seng, Koh Liang


This paper presents the design of a transputer-based Intelligent Character Reader (ICR). The implementation of the ICR is based on two algorithms. The Filtered Projection Technique (FPT) is a modification of the conventional projection profile techniques - it filters out and projects the structural information of a visual pattern into several components along several directions, such that some salient structural information can be extracted from these components easily. The Structural Complexity Index (SCI) algorithm determines the structural complexity of a visual pattern and produces the corresponding index to indicate its relative complexity. The ICR is capable of recognizing printed characters, such as the Chinese characters printedon the local newspapers, accurately, despite the presence of noise due to printing, scanning, slight font variations and misalignment. The ICR prototype is implemented on Occam II and C, and run on an array of transputers.
