Recognition of On-Line Hand-Drawn Graphical Symbols Based on BP Neural Network

The on-line recognition of hand-drawn graphical symbol is an intelligent graphics recognition, it can help people mark the symbols on the electronic map quickly and efficiently. In this paper, on the basis of the study of on-line identification method of hand-drawn graphical symbols, we have established a neural network model of on-line hand-drawn graphical symbols identifying and have developed a hand-drawn graphical symbols on-line authentication system with a good result of on-line hand-drawn graphical symbol recognition.
