SendMode Input
;SendInput 和 SendPlay 与 Send 使用相同的语法, 但通常更快更可靠. 此外, 它们缓存了发送期间任何物理的键盘或鼠标活动, 这样避免了在发送时夹杂用户的键击。
SetWorkingDir %A_ScriptDir% ;让脚本无条件使用它所在的文件夹作为工作目录。

在opencv中关于视频的读操作是通过VideoCapture类来完成的；关于视频的写操作是通过VideoWriter类来实现的。
VideoCapture既支持从视频文件(.avi , .mpg格式)读取，也支持直接从摄像机(比如电脑自带摄像头)中读取。

/*
默认构造函数，生成一个矩阵并由OpenCV提供的函数(一般是Mat::create() 和 cv::imread() )来分配储存空间。
Mat类可以分为两个部分：矩阵头和指向像素数据的矩阵指针
矩阵头 包括数字图像的矩阵尺寸、存储方法、存储地址和引用次数等，矩阵头的大小是一个常数，不会随着图像的大小而改变，
但是保存图像像素数据的矩阵则会随着图像的大小而改变，通常数据量会很大，比矩阵头大几个数量级。这样，在图像复制和传递过程中，
主要的开销是由存放图像像素的矩阵而引起的。因此，OpenCV使用了引用次数，当进行图像复制和传递时，不再复制整个Mat数据，而只是复制矩阵头和指向像素矩阵的指针
*/

bool VideoCapture::open(const string& filename);

功能：打开一个视频文件或者打开一个捕获视频的设备（也就是摄像头）
参数:
filename – 打开的视频文件名。
device – 打开的视频捕获设备id ，如果只有一个摄像头可以填0，表示打开默认的摄像头。

第二个参数DST:输出与src相同大小和深度的图像。
第三个参数code:颜色空间转换的标识符，opencv cvtcolor支持的空间转发code放在下面文中

cvtColor 函数颜色空间(color space)说明
色彩空间转换都用到以下约定：8位图像范围是0～255，16位图像范围是0～65536，浮点数的范围是0.0～1.0。黑白图像转换为彩色图像时，最终图像的所有通道都是相同的；但是逆变换(例如RGB或BGR到灰度)，灰度值的计算使用加权公式：
Y=(0.299)R+(0.587)G+(0.114)B
就HSV色彩模式或者HLS色彩模式来说，色调通常是在0～360之间。 在8位图中，这可能出现问题，因此，转换到HSV色彩模式，并以8位图的形式输出时，色调应该除以2。
