I am using contour function to get the contour lines from an image. Now I'd pretend to get only the contour lines created before to make a new image.
I am using [C,h]=contour(a,[0 0]); I have C - ContourMatrix and h - handler.
How can I create a new image (only contour lines) with this C and h ??
Thanks in Advance Mike

a = peaks;
C = contourcs(a, [0 0]);
xy = {C.X; C.Y};
plot(xy{:});

Oops, forgot that one... imshow also flips the axis. Add 'ydir' to the list of properties to copy.

"ContourMatrix is also a read-only contourgroup property that you can obtain from the returned handle." -- matlab docs
