EmguCV：图像灰度化和二值化（VS2010窗体+代码）

一、EmguCV图像灰度化

//原始图像
Bitmap xjBitmapOld = (Bitmap)this.pictureBox1.Image;
//灰度化
Image<Gray, Byte> xjImageGray = new Image<Gray, Byte>(xjBitmapOld);
//显示

this.pictureBox2.Image = xjImageGray.ToBitmap();

二、EmguCV图像二值化

//获取原图

Bitmap xjBitmapOld = (Bitmap)this.pictureBox1.Image;

//灰度化

Image<Gray, Byte> xjImageGray = new Image<Gray, Byte>(xjBitmapOld);

//二值化

double xjThreshold = (double)this.nudBinaryzation.Value;//二值化阈值

var xjImageBinaryzation = xjImageGray.CopyBlank();

CvInvoke.Threshold(xjImageGray, xjImageBinaryzation, xjThreshold, 255, ThresholdType.Binary);

//显示

this.pictureBox2.Image = xjImageBinaryzation.ToBitmap();
