背景

First, it was to obtain two binary images from segmenting image by two thresholds. Second, erosion, opening and closing were done to the two images according to some knowledge of the shape and location of the objects in the image that we have already known. Last, the edge information from the image segmented by a high threshold was put into the image segmented by a low threshold. It is the way to segment and discern circular objects accurately from the complex image and can greatly improve the accuracy rate of discerning.

首先分别根据两个阈值进行分割得到两幅二值图像，然后根据目标是圆形以及其大致位置等先验知识分别对两幅图进行腐蚀，开启，闭合等数学形态学运算，将高阈值分割得到的图像中的边界信息叠加到低阈值分割得到的图像中，实现对复杂背景图像中圆形物体的准确分割与提取，解决了复杂背景图像中物体识别率低的问题。

Meanwhile, the close-renti than the close-in screen also includes a little background, this background can often play account of the environment, beautify the screen role.

同时，近景renti比特写能在画面中也包括一点背景，这点背景往往可以起到交待环境、美化画面的作用。

The paper includes the constitutes of system hardware, image pretreatment, the achievement of parameter detection artithmetic. The main work is as follow: The pater makes use of vanguard genetic algorithms in image segmentation, uses vanguard genetic algorithms to get the image threshold. Using this method we may get different grey vehicles from the background exactly. Used the support vector machine theory to conduct the vehicles automatic sorting simulation research, the simulation result had proven this method could quite be accurate carries on the vehicles type the recognition; Improved based on the background automatic renewal hypothesized examination region algorithm, enhanced timeliness and the accuracy which the vehicles examines; And to has carried on the specify based on the hypothesized examination region imagery processing algorithm realization; In the paper also introduced withdraws the algorithm based on the gradation continuous movement vehicles characteristic to carry on the vehicles the characteristic to withdraw as well as to use the localization method which colored filter same gradation chart processing unifies to carry on the realization method which the vehicles license plate locates.

本文根据智能交通控制与仿真对于交通流量、车辆到达率、车辆速度等交通信息检测的需求，基于视频图像进行了交通信息处理的算法研究与实现，主要工作包括以下几个方面：将先锋遗传算法应用到图像阈值分割中，利用先锋遗传算法寻求全局最优阈值，可以比较准确的将图像中不同灰度的车辆从背景中分离出来；采用支持向量机理论进行了车辆自动分类的仿真研究，仿真结果证明该方法能够比较准确的将车辆的类型进行识别；改进了基于背景自动更新的虚拟检测区域算法，提高了车辆检测的实时性和准确性；并对基于虚拟检测区域的图像处理算法实现进行了详细说明；论文中还介绍了基于灰度连续性的运动车辆特征提取算法进行车辆的特征提取以及采用彩色过滤器同灰度图处理相结合的定位方法进行车辆牌照定位的实现方法。

Design is human"s pondering outcome, it is a kind of conceivableness, proposition too.by actualizing,reaching the terminated aim of satisfying human"s demand .design is influenced by cluture and expresses clu-ture.design conveys ideology ,and architecture carries design.cluture is the distillation of a civilizaiton,and architecture is a kind of the material form of cluture .so design cant be disvorced from societal culture background ,the two parts is so consanguineous.the article is try to use this measure,hunting the cluture background of the aulic archi- Tecture of qing dynasty, seek the path of distinguishing display of qing dynasy and ming dynasy.point out the relationship of design and archi-tecture of different time.

设计在文化的影响下体现出文化的特征；设计通过建筑的形式传达思想，建筑成为了设计的载体；文化是一个文明社会的精髓，而建筑正是文化的一种物化的形式。因此，设计是不能脱离社会文化大背景而独立存在，它们两者之间是密不可分的关系。而本课题正是通过研究清朝宫廷的建筑来探求设计背后的文化背景，为寻求明清陈设的差别找到出路，并指出不同时期设计与文化的关系。以便给以后的研究廓清思路，理顺线索。

No significant differences were found in teachers' gender, education, physical education background, and connubiality in teachers' perception to current status on APE.
