its each operational step produces a string of elements instead of one element. hence the algorithm reduces the time of operation, and accelerates the speed of generation.
该算法每步运算可生成一列元素而不是一个元素,因而减少了运算次数,加快了生成速度。
keywords are not really a profile concept, but they are often used as a lightweight method to mark up elements instead of stereotypes.
关键字并不真的是一个概要文件概念,但是它们通常被用作一个轻量型方法,可以标记元素而不是原型。
structural information is described by using statistical analysis in detecting the road elements instead of using lines extracted, to enhance the algorithm's robustness;
在检测道路基元时,用统计分析来表达道路的结构信息,避免了提取线段来表达,增强了抗噪性与稳健性;
