2014 Lecture Notes in Computer Science  
From this scheme, we derive algorithms that produce curvilinear or surface skeletons, based on the notion of 1D or 2D isthmus.  ...  Critical kernels constitute a general framework settled in the context of abstract complexes for the study of parallel thinning in any dimension.  ...  This discussion motivates the introduction of the following 3D asymmetric and parallel thinning scheme AsymThinningScheme(see also [4, 5] ).  ...

A 3D Sequential Thinning Scheme Based on Critical Kernels [chapter]

Michel Couprie, Gilles Bertrand
2015 Lecture Notes in Computer Science  
We propose a new generic sequential thinning scheme based on the critical kernels framework. From this scheme, we derive sequential algorithms for obtaining ultimate skeletons and curve skeletons.  ...  We prove some properties of these algorithms, and we provide the results of a quantitative evaluation that compares our algorithm for curve skeletons with both sequential and parallel ones.  ...  a criterion based on 1D and 2D isthmuses allows one to obtain robust curve and/or surface skeletons.  ...

Topography of the human corpus callosum revisited—Comprehensive fiber tractography using diffusion tensor magnetic resonance imaging

Sabine Hofer, Jens Frahm
2006 NeuroImage  
With DTI-based tractography, we distinguished five vertical segments of the CC, containing fibers projecting into prefrontal, premotor (and supplementary motor), primary motor, and primary sensory areas  ...  In conclusion, DTI-based fiber tractography of healthy human subjects suggests a modification of the widely accepted Witelson scheme and a new classification of vertical CC partitions.  ...  Not only lead thin fibers to a more severe restriction in water mobility, but also a high density of mostly parallel axon bundles reinforces the MRIdetectable effect.  ...
