Due to the abstraction of logic topology, the algorithm is a framework for broadcast algorithms.
由于逻辑拓扑的抽象性，因此，该算法是个一到多广播通信算法框架。

We propose a road-surface abstractionalgorithm which is suitable for structured or semi-structured road environment and extracts effectively a road-surface for ground robot navigation.
On the basis of resolving to Chinese character stroke, this thesis presents the abstractionalgorithm which recognition code used according to the character characteristic.
