本文介绍了一个基于Hough变换的圆检测算法实现过程。通过用户界面获取参数，如距离精度dp、最小距离minDist等，并应用于摄像头捕获的图像上进行圆检测。当检测到圆时，会在界面中显示圆的位置和半径，并调整图像大小以适配显示区域。

{
	// TODO: 在此添加控件通知处理程序代码

	static int countnum=0;
	char filename[200]; 

	CString Text_dp,Text_minDist,Text_param1,Text_param2,Text_minRadius,Text_maxRadius,Text_downGrayValue,Text_upGrayValue;
	GetDlgItemText(IDC_EDIT_dp, Text_dp);
