Based on the criteria of the shortest path of curves and directional deviation of paths, principal curvedetection is carried out in graph domain.
基于曲线最短路径和方向偏移判据,主曲线检测的所有运算都在图形表达中进行。

Since characters and map symbols often overlap with useful image features, the algorithm of principal curvedetection aims to obtain "clean" feature images from the original maps.
