Use 3D Regions as 3D Image Masks
The 2D and 3D image processing framework is linked to the geometric computation framework via ImageMesh and RegionImage. Some operations are easier to define in one domain or another. The connection allows you to go back and forth while working on an algorithm prototype.
Here is an orthopedic example. Given a CT scan of a spine, generate a mesh model of an intervertebral disc for replacement.
Regularize the volumetric data with a bilateral filter and segment the bone tissue with a density threshold.
Obtain a mask of the intervertebral disc via morphological operations.
Generate a boundary mesh of the intervertebral disc.
The mesh can be stored as a DXF file for further processing or 3D printing.
Display the intervertebral disc model between the vertebrae.
