| Abstract: | In this paper,the authors have investigated the vectorization algorithm of linear features based on the tracing circle,and studied the features and shortcomings of this way,on the basis of that,the authors have promoted the progressive vectorization algorithm based on the tracing frame,and with the help of VS2005,finished the vectorization programe of linear features in the C＋＋ langwage.Test has showed that： the progressive vectorization algorithm based on the tracing frame is a very excellent algorithm which is simple, fast , saving computer space of storage and easy to programm, the results of vectorization are very useful. |
