通过OpenCV的camshift算法控制鼠标指针（或鼠标基本上如何工作）(Controlling mouse pointer through camshift algorithm of OpenCV (or how mouse basically functions))

 我使用EmguCV（openCV的包装器）在C＃中编写了一个程序。 程序使用camshift算法跟踪对象。 在对象周围绘制一个矩形。 光标移动到矩形的中心。 输入来自网络摄像头。 
 
 最初的问题是光标无法覆盖整个屏幕。 它的移动仅限于框架尺寸。 所以我应用了一个乘法因子： 
 
 在X方向上移动的screenwidth / framewidth。 
 
 屏幕高度/框架高度在Y方向上移动 
 
 有了它，鼠标覆盖整个区域。 但鼠标移动不再平滑。 我无法指出两个紧密相连的图标。 如何在覆盖整个屏幕时使鼠标移动平滑，就像真正的鼠标一样？ 

I have written a program in C# using EmguCV (wrapper of openCV). The program tracks an object using camshift algorithm. A rectangle is drawn around the object. The cursor is moved by center of the rectangle. Input is taken from a webcam. 
 
Initially the problem was that the cursor couldn't cover the entire screen. Its movement was limited to frame size. And so i applied a multiplication factor:
 
screenwidth/framewidth for movement in X direction.
 
screenheight/frameheight for movement in Y direction
 
With this the mouse covers entire area. But the mouse movement is not smooth any more. I am unable to point to two icons closely situated. How can I make mouse movement smooth while covering the entire screen, just as it happens with a real mouse?
