Reliable estimation of membrane curvature for cryo-electron tomography

Application of curvature estimation algorithms to other data types.
(A) Surfaces of C. elegans embryo cells imaged by confocal light microscopy and segmented by LimeSeg [22], colored by Gaussian curvature (μm-2) estimated by AVV using rh = 3 μm (scale bar: 5 μm). (B) Cortical pial surfaces of both human brain hemispheres imaged by MRI and segmented by FreeSurfer [52], colored by mean curvature (mm-1) estimated by AVV using rh = 2 mm (scale bar: 20 mm). Panels (C-D) show the same brain surface colored by mean curvature (mm-1) with the same color scale as in (B) estimated by (C) Mindboggle (MB; using n = 2 mm) and (D) FreeSurfer (FS).
