associated to the m th stimulus type with the canonical HRF , i.e. a composition of two gamma functions which reflects the BOLD signal best in the visual and motor cortices [8]….
and be two images that are geometrically related by the registration transformation with parameters such that voxels p in with intensity a correspond to voxels in with intensity b. Taking…
Fig. 1 Object extraction methods using contour/surface energy functionals. Only a few representative references are shown for each method Note that graph cut methods for object extraction, e.g. [4, 8,…
with the tensor D being the unknown variable and b a value that depends on the acquisition settings. The estimation of the tensors in the volume domain Ω can be…
Fig. 1 Sketch of HARDI reconstruction techniques In this chapter, we focus on deterministic and probabilistic tractography using state of the art reconstruction of the diffusion and fibre ODF from QBI….
the spatial domain ( in the continuous case or in the discrete case). Fuzzy sets can be considered from two points of view. In the first one, a membership function…
which maps any point in the target image I A into its corresponding point in the source image I B . The transformation can be separated into two components: A…
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…
