A New Boundary Extraction Algorithm In A Binary Image

(Department of Computer Science,Guangxi Normal University, Guilin 541004) Tang,Zhenjun Zhang,Xianquan  
A new boundary extraction algorithm in a binary image is proposed. An operator is induced by analyzing the feature of the boundary pixel. It just needs four pixels at most, so the computation is small and the speed is fast. Using the operator of boundary extraction, the algorithm can directly extract the boundary pixels from the binary image and get one pixel width boundary. The experi- mental results show that the new algorithm is better than the traditional algorithms in a binary image and is practicable.
