Correction of zoomed morphology-based interpolation of contours

In medical imaging, a 3D object must often be reconstructed from serial cross-sections. Usually, the cross-sections are not closely spaced so that interpolation is needed to solve the problem of anisotropy. Different interpolation technique exist, applied either on slices either on objects. Recently, a new contour interpolation method based on a zooming transform and on mathematical morphology has been developed. Thanks to the zooming transform, it works in any case. But, the obtained results are bigger and not so smooth as one could wish. This paper proposes a correction of the method in order to avoid so big results.
