Am i getting this error because of in place resizing? i.e. I use the same var like so (resize,var,var ..) It's probably not the right thing to do but it seems to work, now i'm not so sure. I see it in other code with grayscale, equalizeHist etc.

error: (-215) ssize.area() > 0 in function resize

and it seems to happen especially when i move my face really fast (lots of data to resize?)

It means the image you're passing in has either no rows, no columns, or both. Why? I don't know, I have no context to guess by.

Hmm ok thanks, so it's not due to inplace resizing?

Correct. The assert happens before anything else, so all it does is read the size of the input image.

Thanks, that's good to know. It does explain why when i moved my face out of the camera it immediately crashed. I need to check if the face Mat is empty().

Thanks again.
