  Slice interpolation is a fast growing field in medical image processing.
Intensity-based interpolation and object-based interpolation are two major
groups of methods in the literature. In this paper, we describe an
object-oriented, optimization method based on a modified version of
curvature-based image registration, in which a displacement field is computed
for the missing slice between two known slices and used to interpolate the
intensities of the missing slice. The proposed approach is evaluated
quantitatively by using the Mean Squared Difference (MSD) as a metric. The
produced results also show visual improvement in preserving sharp edges in
images.
