Peters used a technique called DGS, which involves applying the digital tracing features of photo editing software to images of pterosaur fossils.
In this model, the component accounting for the contact-tracing feature is assumed to be valued in a space of point measures in order to take the time since detection into account.
The 'verb trace' feature is computed in a similar manner, except that we collect the POS tags of the verbs appearing in the corresponding paths.
The 'preposition trace' feature is computed by (i) collecting the list of prepositions along the path from e1/ e2 to the root of its syntactic parse tree and (ii) concatenating the resulting lists computed from e1 and e2.
To support the tracing, crack features are highlighted by hillshade image and local variation of elevation (3 × 3 cell statistics) calculated from the DEM.
Importantly, unlike LCM, no manual tracing of features is required with STOMP.
The segmentation of tomographic reconstructions was performed by manually tracing structural features through sequential slices of the tomograms.
With regard to lineage-specific trends, we include an explicit phylogenetic component by tracing several features of overlapping genes through a consensus prokaryotic phylogeny making use of squared change parsimony.
"Without a Trace," featuring Mr. LaPaglia, Ms. Montgomery, Marianne Jean-Baptiste, Enrique Murciano and Eric Close as F.B.I. agents who look for missing persons, finished the year among prime-time's top 20 shows.
Ray-tracing features have, for example, been incorporated into Pixar's RenderMan software, a shader-based rendering tool that is used internally, but which Pixar also sells to other companies.
