| Abstract: | Based on the analysis of the extracted linear feature from remote images,this paper studies the vectorizating representation of the linear feature by spline interpolation function.The process includes the decomposition of line feature,the selection of interpolation knots,the selection of interpolation function,and the addition of interpolation knots.The experiments show that the proposed method can represent the extracted feature effectively,and reduce the data redundancy,and is with good smooth. |

| Keywords: | linear feature representation spline interpolation function vectorization |
