Convert int/byte[] or Bitmap to the Mat type of openCv

Hi AhmedWassimBENSALEMENISo-3626,
To use OpenCvSharp, you need to add both OpenCvSharp4 and OpenCvSharp4.runtime.* packages to your project.

Right-click your project namre->Manager NuGet Packages->Browse-> Search and Install them.
Then you can achieve it via BitmapConverter.ToMat() method.
Here is my test code you can refer to.

Image img = Image.FromFile(@"C:\Users\Pictures\home.PNG");  
Bitmap bmpScreenshot = new Bitmap(img);  
var imageMat = OpenCvSharp.Extensions.BitmapConverter.ToMat(bmpScreenshot);  

Best Regards,
