Data Processing Pipeline

• Image Processing consists of the following modules, applied to the raw imaging data as per need. The algorithm modules include



1. Image Contrast Enhancement
2. Filtering/Noise Reduction
3. Image Segmentation
4. Boundary-free Image Skeletonization
Working implementations of the above image processing modules are all encapsulated in our in-house 3D Interactive Image Visualization software VolRover


• Geometry Processing step consists of the following modules, applied to the set of boundary voxels of the segmented regions of interest.


A. Initial Model Construction from Segmented Voxel Map

1. Contouring
2. Tracing and Tiling
3. Reconstruction from Point Cloud

B. Feature Analysis and Curation

1. Medial Axis Construction
2. Feature Segmentation using Critical Point Analysis
3. Geometry Skeletonization and Feature Annotation
4. Quantification of Complementary Space Topology and Selective Removal of Topological Noise

C. Quality Meshing

D. Higher Order Model Construction

1. A-Patch Modeling
2. NURBS Modeling
