I have a set of images that a taken from single point of view but with different focal length, kinda like computer tomography slices. So by stacking them up I can form 3d image of object.
I need to find a "contour" of 3d objects. For now i see only brute force way: stack images in 3d cvMatND, do X, Y and Z slices and use cvFindContours().
Is there more intelligent way to do this?
