Description: 使用说明 使用时打开此例题目录下pic中的图片,然后依次单击按钮“转”、“1”、“2”、“3”、“4”和“5”,就可以实现精确的车牌定位。 具体步骤 1.24位真彩色->256色灰度图。 2.预处理:中值滤波。 3.二值化:用一个初始阈值T对图像A进行二值化得到二值化图像B。 初始阈值T的确定方法是:选择阈值T=Gmax-(Gmax-Gmin)/3,Gmax和Gmin分别是最高、最低灰度值。 该阈值对不同牌照有一定的适应性,能够保证背景基本被置为0,以突出牌照区域。 4.削弱背景干扰。对图像B做简单的相邻像素灰度值相减,得到新的图像G,即Gi,j=|Pi,j-Pi,j-1|i=0,1,…,439 j=0,1,…,639Gi,0=Pi,0,左边缘直接赋值,不会影响整体效果。 5.用自定义模板进行中值滤波 区域灰度基本被赋值为0。考虑到文字是由许多短竖线组成,而背景噪声有一大部分是孤立噪声,用模板(1,1,1,1,1)T对G进行中值滤波,能够得到除掉了大部分干扰的图像C。 6.牌照搜索:利用水平投影法检测车牌水平位置,利用垂直投影法检测车牌垂直位置。 7.区域裁剪,截取车牌图像。-my english is poor

Description: 使用子像素的方法来减轻图像系统的负荷已经是目前主流3D程序中的必用方法。比如知道Sin函数的特性,就只需要计算0~pi/2的点就可以了,剩下的pi/2~pi可以通过子像素来画出,在图形量大的情况下可以减轻至少一半的系统压力。 这个程序不光可以加速Sin函数的显示,还可以加速所有函数的显示。 -The use of sub-pixel image of the ways to reduce the load on the system is already the existing procedures of the mainstream 3D methods will be used. For example, to know the characteristics of Sin function, we only need to calculate 0 ~ pi/2 could be the point, and the rest of pi/2 ~ pi can be sub-pixels to draw, in the graphic case of a large quantity can be reduced at least half of the system pressure. This process not only speed up the Sin function can be shown that all functions can also speed up the display.

Since frustration seems to be a negative feeling, some people may be tempted to think that frustration is bad for people. They believe that constant frustration may cause serious mental problems. People suffering from such psychological problems often resort to violence or suicide, which poses a big threat to the people around them and thus causes instability to the whole society.
