Getting imcontour matrix without the plotting

Is there a way to silently get the imcontour matrix C without having the contour plot?
[C,h]=imcontour(frame, 3);
I've tried using contourc, but I think I have to manipulate the image matrix to input into this function? I'm not sure how to though.
Any help would be appreciated!

C = imcontour(IM, oneLevel); % will open a figure, whereas
C = contourc(double(IM), [oneLevel oneLevel]); % will be silent and faster%
Kind regards,

imcontour just parses its arguments and calls contour(). For the arguments you provide, calling contourc with the same arguments would create the contours you want without plotting them.
