Development of a Computer-aided System for Automating Tactile Graphics Translation of Mathematical Graphs

摘要

Tactile graphics are images that use raised surface so that a visually impaired person can feel them. Tactile graphics are necessary to visually impaired students when they study mathematics and science. Since producing tactile graphics are not simple task, an intelligent computer-aided system for assisting the production of tactile graphics is needed. So, we are developing a computer-aided system for automating tactile graphics translation of mathematical graphs. Mathematical graph recognition from printed materials plays an important role to develop such a system. So, this paper describes part of a method of mathematical graph recognition: extraction and classification of mathematical graph elements.
