Overview of contour-based reconstruction with MPU implicit models..A point set is extracted from a stack of contours and filled to produce a binary volume. The object’s boundary is blurred and gradients are calculated at exterior voxels (boundary points) to estimate surface normals. An MPU implicit model is fit to the points and normals to produce a 3D scalar field. A mesh of the zero iso-surface is then extracted from the volume.
