c# - 将 System.Drawing.Image 转换为 Emgu.CV.Image

Question

有什么方法可以使用 C# 在 EmguCV 上将 System.Drawing.Image 类型的图像转换为 Emgu.CV.Image 类型的图像，反之亦然？如果需要额外解释这样做的目的，我将根据您的要求进行解释。

Answer 1

// Converting the master image to a bitmap
Bitmap masterImage = (Bitmap) pbxMaster.Image;

// Normalizing it to grayscale
Image<Gray, Byte> normalizedMasterImage = new Image<Gray, Byte>(masterImage);

Answer 2

EmguCV 版本 4.2.0.3636 [和转发] 使用以下代码：

using System.Drawing;
using System.Drawing.Imaging;
using Emgu.CV;
using Emgu.CV.Structure;

//inputImage type is System.Drawing.Image
Bitmap bitmapImage = new Bitmap(pictureBox1.Image);

Rectangle rectangle = new Rectangle(0, 0, bitmapImage.Width, bitmapImage.Height);//System.Drawing
BitmapData bmpData = bitmapImage.LockBits(rectangle, ImageLockMode.ReadWrite, bitmapImage.PixelFormat);//System.Drawing.Imaging

Image<Bgr, byte> outputImage = new Image<Bgr, byte>(bitmapImage.Width, bitmapImage.Height, bmpData.Stride, bmpData.Scan0);//(IntPtr)
//outputImage type is Emgu.CV.Image
