Topology Smoothing for Segmentation and Surface Reconstruction

  title={Topology Smoothing for Segmentation and Surface Reconstruction},
  author={Pierre-Louis Bazin and Dzung L. Pham},
We propose a new method for removing topological defects in surfaces and volumes segmented from medical images. Unlike current topology correction approaches, we define a smoothing operator that acts solely on the image volume and can be integrated into segmentation procedures. The method is based on an analysis of the scalar field underlying the isosurface of interest, and performs only local changes. No assumptions are required on the structure to segment, or on the desired topology. We show… CONTINUE READING
