基于最大类间方差阈值与遗传算法的道路分割
最大类间方差法是由日本学者大津(Nobuyuki Otsu)于1979年提出的,是一种自适应的阈值确定的方法,又叫大津法,简称OTSU。它是按图像的灰度特性,将图像分成背景和目标2部分。背景和目标之间的类间方差越大,说明构成图像的2部分的差别越大,当部分目标错分为背景或部分背景错分为目标都会导致2部分差别变小。(The largest between-class variance method was proposed by the Japanese scholar Nobuyuki Otsu in 1979. It is an adaptive threshold determination method, also known as the Otsu method, or OTSU for short. It is based on the grayscale characteristics of the image and divides the image into two parts: the background and the target. The larger the variance between the background and the target, the greater the difference between the two parts that make up the image. When the part of the target is wrongly divided into backgrounds or part of the background is mis-divided into goals, the difference between the two parts will be smaller.)

Voronoi1
Voronoi图是以两点间线段的长度作为距离 ,对平面的一种分割。然而 ,在地理环境中 ,存在着许多自然的或人为的障碍 ,使得从一点到另一点不能直线到达。为了扩大Voronoi图的应用领域 ,本文对传统的Voronoi图进行扩充 ,给出了障碍Voronoi图的定义、性质 ,以及离散生成线段障碍Voronoi图的方法(Voronoi diagram based on the length of line between two points as the distance from a partition of the plane. However, in the geographical environment, there are many natural or man-made obstacles, making from one point to another point of arrival can not be a straight line. In order to expand the area of Voronoi diagram, Voronoi In this paper, the traditional expansion plans, given the obstacles to the definition of Voronoi diagram, the nature of the discrete Voronoi diagram generation segment of the barrier method)
