I have a source that gives me a jpeg in memory stream (Bytes).
I can convert it to System.Drawing.Image but I don\'t know how
to convert it to Emgu Image.
You can convert your array bytes to Emgu Image<,> with a code like the following...
public Image CreateImageFromBytesArray(byte[] bytes)
{
MemoryStream ms = new MemoryStream(bytes);
Bitmap bmpImage = (Bitmap) Image.FromStream(ms);
return new Image(bmpImage);
}
