Abstract
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. Mathematical graph recognition from printed materials plays an important role to develop such a system. So, this paper focuses on part of a method of mathematical graph recognition: a method for extracting and classifying broken line graphs in mathematical figures.
