It has obvious drawbacks in terms of a loss of accuracy in computing the eigenvalues and eigenfunctions, though these can be minimized by an appropriate choice of trial functions, segmentation geometry and number of segments.
It has been found that the TSIF is a monotonically increasing function of segmentation crack spacing.
While this is sufficient for computing most of the common clinical quantitative parameters for cardiac function, a segmentation of the left heart's epicardium would provide additional clinical information.
The phosphorylation patterns of pMadMAPK and pMadGSK3 suggested that linker phosphorylation could function during segmentation (Figure 3L and 3O).
In spite of the importance of proper nephron function and segmentation, little is known regarding how the nephron patterns and how different specialised segments form during nephrogenesis.
The significance of the posterior expression domains of eve in Nasonia and other arthropods is still not entirely clear, but it remains a possibility that it is in some way distinct from its expression in stripes and function in segmentation.
Drosophila ets21c has been described as an immune-regulated gene induced in response to immune challenge and wounding (Boutros et al., 2002; Park et al., 2004; Radyuk et al., 2010; Chambers et al., 2012; Patterson et al., 2013), whereas Ftz-F1 is a founding member of the NR5A family of nuclear receptors with an essential function in segmentation and metamorphosis (Pick et al., 2006).
Despite operational differences, previous studies had revealed that canonical functions of segmentation genes are fundamentally conserved between long germ and short germ segmentation (Mito et al., 2005; Mito et al., 2006; Mito et al., 2007).
Second, the user may use our semiautomatic segmentation functions to delineate the tumor.
Parametric methods of incorporating shape information impose this knowledge directly into the level set by defining the level set as the output of some parametric function and minimising segmentation energy functionals with respect to these parameters.
