how to convert mat to image

Question

I need to convert a Mat to an Image in Emgu CV. Trying to cast a Mat to an image produces an exception: Cannot implicitly convert type 'Emgu.CV.Mat' to 'Emgu.CV.Image

Image<Bgr, Byte> imgeOrigenal;

Capture capWebcam = null;

imgeOrigenal = capWebcam.QueryFrame();//error line

How can I convert the Mat to an Image?

It is nice to know that you need testet AND working code. Please remember that stackoverflow isn't a code generator. What have you tried so far to convert your Mat? Have you tried the following: *Image img = mat.ToImage();*? Its not tested but should work. — David_D, Jan 21 '16 at 09:16

In can you want to show the image in a pictureBox or a dataGridView, you can also load the image as a Bitmap object like this:

imgeOrigenal = new Bitmap(capWebcam.Bitmap);

I do it like this (and seems to work fine for all my purposes):

//BGR
Image<Bgr, byte> grayframe = yourMat.Clone().ToImage<Bgr, byte>();

//GRAYSCALE
Image<Gray, byte> grayframe = yourMat.Clone().ToImage<Gray, byte>();
