The sensitivity (B ), positive predictive value (PPV, C ), and the harmonic mean (D ) for male bout (blue) and female pulse (red) calls (n = 15 courtships), calculated by comparing manual versus automated segmentation (see 'Materials and methods').
Following this, the segmentation surface models were computed with a voxel-sustaining algorithm matching the exact voxel boundaries of each segmented material.
The workflow is based on routinely acquired tomographic data and consists of an automatic segmentation and material assignment, followed by a mesh generation step and, finally, a mechanical simulation using the finite element method (FEM).
Inhibition of Wnt signaling by axin1 overexpression dramatically slowed embryonic elongation, thus preventing specific analysis of segmentation (supplementary material Fig. S1A-C′, Movie 1).
We applied semi-automatic segmentation (supplementary material Methods) based on gradient detection to highlight structures such as brain domains, brain ventricles and retinas (Mueller and Wullimann, 2005) (colored in Fig. 1C-E; supplementary material Fig. S1 and Movie 3).
In a TEM image, circularity is defined as the ratio of the area of a nanoparticle with its perimeter, determined via segmentation (see the 'Materials and methods' section).
We have also derived a new class of photometric invariants that can be used for a variety of vision tasks including lighting invariant material segmentation, change detection and tracking as well as material invariant shape recognition.
The 3D data can also be manually segmented (see Materials and Methods), and rendered in different colours according to the segmentation label.
As a demonstration, we present the results of applying data recovered by our system to material segmentation and spectral relighting.
Although it is difficult to single out the seismogenic mechanism from a number of proposed models, more detailed discussions of the relationship between hypocenter locations, fault segmentation and the material structure contrast around the plate boundary, are important for considering the seismogenic mechanism in terms of metamorphic environments (e.g., Hyndman and Peacock, 2003).
Figure 10A illustrate that potato tubers were clearly distinguishable from the surrounding soil, and a histogram demonstrated that segmentation of tuber material was possible.
