Can someone tell me how to extract the face detected and then do some extra detection ? I just need to get the face’s image croped in all frames…

thanks in advance

When i run this code i get an exception at the line Image grayframe = nextFrame.Convert(); and it says that this "conversion is not supported by OpenCV" Now can anyone tel me how to solve it? Hi. When i run this code i get an exception at the line

Let me try again: using (Image<Bgr, Byte> nextFrame = cap.QueryFrame()) and Image<Gray, Byte> grayframe = nextFrame.Convert<Gray, Byte>(); Ah, I see that the blog software is stripping out the greater-than and less-than so my code snippets got edited.

This is really helpful. For those getting the compile error, you'll need to specify params to the Image object to ensure that it's using Engu.CV.Image and not System.Drawing.Image: using (Image nextFrame = cap.QueryFrame()) and Image grayframe = nextFrame.Convert(); Thanks for posting your code.

Lada I have this problem when i complie:
using (Image nextFrame = cap.QueryFrame())

Cannot convert type ‘Emgu.CV.Image’ to ‘System.Drawing.Image’

Thanks for help. Lada

It says that 'var' could not b found and 'Emgu.CV.HarrCascade' does not contain a definition for 'rect' and 'face' cannot be declared in this scope becaue it would give a different meaning to 'face, which is already used in a 'parent or current'.

It says that ‘var’ could not b found

and ‘Emgu.CV.HarrCascade’ does not contain a definition for ‘rect’

and ‘face’ cannot be declared in this scope becaue it would give a different meaning to ‘face, which is already used in a ‘parent or current’.
