With the advancement of science and technology, some new theories and new ways emerged gradually, some of them merged with specific theoretical tools, this specific theoretical tools include mathematical morphology, fuzzy techniques, neural networks, wavelet and so on. Secondly, in this paper, it described and analyzed the segmentation method based on the edge in the domain of image segmentation in detail. It did experiments on several edge detection operators using MATLAB, it summarized the advantage and the shortcoming of traditional edge detection operators, and the operating environment. On the basis of the experimental analysis, it implemented an edge location more precise, more efficient operating speed edge extraction method——Template Vector. In this method, it optimized differential approximate calculation of first differential operators the paper mentioned. After experimented on this edge extraction method, contracted with the traditional methods, the edge outline is extracted more accurately and more exquisitely, furthermore, it retained the object outline furthest, and achieved more satisfied edge extraction result.

其次，对图像分割领域中常用的基于边缘的分割方法进行了详细的研究与分析，对各种边缘检测算子进行了MATLAB环境下的实验，分析总结了各种传统边缘检测算子的优缺点和适应环境，并针对传统边缘检测算子在处理显微图像时的缺陷，在实验分析的基础上研究并实现了一种边缘定位更加精确、运算速度更加快捷的边缘提取方法——模板向量算法，在该算法中，对文章提到的一阶微分算子中微分的近似计算作进一步优化，经过对该边缘提取方法进行实验，其结果与传统方法相比，轮廓提取更为精确细腻，且最大程度的保留了图像中物体(目标个体或者明显噪声点)的轮廓，得到了比较理想的边缘提取效果。

In still a further feature of the invention, the windshield has a vision area having a top edge and a bottom edge, and the coating has a top edge adjacent the top edge of the vision area and a bottom edge adjacent the bottom edge of the vision area.

在本发明的另一个特征中，所述挡风玻璃具有一个视区，所述视区具有顶边和底边，所述涂层具有毗邻所述视区顶边的顶边以及毗邻所述视区底边的底边。

By comparing the common edge detection algorithms, the magniloquent Kirsch edge detection algorithm is selected to process the result of background subtraction. The result of edge detection is denoised by mathematical morphology method. Shadow edge restrained arithmetic and detection-line-based background updating method are presented. Shadow edge restrained arithmetic reduces vehicle shadow edge efficaciously. Background updating precision is improved by presented background updating method.

在处理过程中，对常用的背景差方法进行了改进，有效的保留了车辆目标信息；通过对常用的边缘检测方法比较，选用了突出边缘的Kirsch边缘检测方法对背景差后的图像进行了边缘检测；使用形态除噪算法对边缘检测的结果进行了噪声去除；提出了阴影边缘去除算法和基于检测线的背景更新方法，阴影边缘去除算法有效的抑制了车辆阴影边缘，背景更新方法则提高了背景更新的精度。

leading edge：前缘

Cell杂志近期在其前缘(leading edge)栏目刊登了发展中国家科学院(TWAS)执行主席Mohamed H.A. Hassan博士的评论文章. 曾在水生生物研究所作博士后研究的Citarasu Thavasimuthu博士在该所工作时的照片作为发展中国家科学院"南-南合作"的三个典型事例之一被Hassan博士在文中采用.

leading edge：前沿

光孤子大多存在具有波形的媒介中,在光纤应用中,光孤子能在非线性射散迁移光纤中产生,其每个脉冲的后沿(trailing edge)均快于前沿(leading edge). 如此在光纤长度内,波的峰值放大率将会增加而非减少,从而在不使用增益器情况下产生惊人的放大率.

leading edge：翼前缘

通常设计图上都有标示最高线所在,若图上没有标示,则可自行将其标在翼弦(Chord)长度之30%~35%处.接着在最高线距翼前缘(Leading edge)的 1/2处画上一条线,及最高线离翼后缘(Trailing edge)的 2/3处画上一条线.并在翼前缘及后缘各画上一条高度约1mm左右的水平线.

leading edge：导缘

辅旋翼的直径较小,转向与主旋翼相反,藉以抵消可能造成机身旋转的主旋翼反作用力. 主旋翼的叶片数,少者二叶,多至七叶. 各叶片的导缘(leading edge)均朝上形成一倾角(相当於螺距角pitch angle),以便使叶片与气流之间存在一攻角(angle

leading edge vortex：前缘涡
