1. A computer-implemented method comprising:
obtaining, by one or more processors, volumetric data that represents a first volume including one or more three-dimensional (3D) volumetric objects;
determining a plurality of planar slices of the first volume, wherein each planar slice includes a plurality of voxels that depict an associated planar portion of the first volume;
for each of the planar slices of the first volume:
determining a result region and a continuity region in the planar slice, wherein the continuity region is located between the result region and an edge of the planar slice;
determining a target region within the result region, the target region being adjacent to an edge of the result region; and
modifying, by the one or more processors, the result region by updating a plurality of source voxels in the target region based on corresponding continuity voxels in the continuity region, wherein the updating is weighted based on a distance of each source voxel from an associated edge of the result region; and
grafting the modified result regions of the planar slices of the first volume to a second volume at the edge of the result regions to provide a grafted volume.
