如何将图像类型转换为图像<Bgr, Byte> ?

Question

Any Idea how to convert Image type to Image<Bgr, Byte> type?

I get the image from PictureBox Control and I need to convert it to Image<Bgr, Byte> type.

Image pictureBoxImage = pictureBox.Image;
Image<Bgr, Byte> image = // ...

Answer 1

According the documentation :

Creating image from Bitmap

It is also possible to create an Image<TColor, TDepth> from a .Net Bitmap object

So, you should be able to do:

var image = new Image<Bgr, Byte>(new Bitmap(pictureBox.Image));

Answer 2

You can also do it like this:

Image<Bgr, Byte> IMG = new Image<Bgr, byte>((Bitmap)pictureBox1.Image);

OR

var IMG = new Image<Bgr, byte>((Bitmap)pictureBox1.Image);

Answer 3

For Emgu.CV 4.5 I had to add the Emgu.CV.Bitmap package and use bitmap.ToImage<Bgr, byte>() :

using (Bitmap bitmap = new Bitmap(pictureBox.Image))
{
    Image<Bgr, byte> image = bitmap.ToImage<Bgr, byte>();
}
