Fig. 1 a) Subcortical structures have a spherical topology. For instance, the shape of the hippocampus can be continuously deformed onto a sphere. b) The human cerebral cortex is a…

Fig. 1 Atlas MRI and labeled image from Harvard Medical School [58]. Atlas-based segmentation results (ventricles, corpus callosum, thalamus, trunk and cerebellum) using a tandem of affine registration and Demons algorithm as…

with A p ∈ {“obj”, “bkg”} can be used to represent the segmentation of P into object (“obj”) and background (“bkg”) voxels. Let N be the set of unordered neighboring…

is often chosen to be a signed distance function of the embedded contour(s). Such a signed distance function can be computed very efficiently using the fast marching method [94, 109] or…

used to describe the region of interest D consists of four elements, namely, a probabilistic atlas (), texture-based features (), relationships , and specific segmentation methods for organs in the…

Fig. 1 Sketch of the haemodynamics simulation pipeline Image segmentation here refers to the extraction of the boundaries of vascular objects from a 3D image. The outcome is a binarization…

Fig. 1 Coronal Cine MRI slices visualizing the peristaltic wave in the descending colon In order to integrate such a novel imaging technique into the daily clinical routine, it is mandatory…

Fig. 1 The mouse skeleton as included in the atlas (top) and after segmentation of single bones and adding joints (bottom)(adapted from [2], ©2007 IEEE) Three types of joints have to be…

Fig. 1 The feature space is defined by the cross-section center position x = (x 1, x 2, x 3), the cross-section tangential direction Θ = (θ 1, θ 2, θ 3) and the…
