Another topological descriptor is the Minkowski functional contour length, which is also plotted for both tumor types (astrocytoma: red curves, and glioblastoma multiforme green curves) in Figure 9.
This will be labelled as "Clinical Plan" and placed in the treatment system for standard quality assurance, and functional lung contours will be removed from that plan to maintain blinding.
Relaxed geometries, binding energies, charge differences of the adsorbed CrO4 2− anions, and electronic wave function contour plots were calculated using B3LYP hybrid exchange-correlation functional.
To allow contour splitting and merging naturally (i.e., a change of topology), we use a level set function to represent a contour C. The IFE functional of the contour C is thus changed into the energy functional which is directly defined on the level set functions.
The authors propose a modified energy functional via active contour models based on complex Gaussian and Wishart distribution models for both single- and multilook PolSAR images segmentation.
In our method, a modified energy functional via active contour model is proposed based on complex Gaussian/Wishart distribution model for both single-look and multilook PolSAR images.
In contrast to complex cells in V1 they respond much stronger if the luminance contrast is continuous, and less if gaps are between inducers, thus resembling functional properties of contour neurons in V2.
Repair of facial defects using interpolation flaps requires an appreciation of variations in skin thickness, facial contours, and functional concerns at the donor and recipient sites.
The algorithm is based on minimizing piecewise constant Mumford Shah functional in which the contour length (or perimeter) is approximated by a non-local multi-phase energy.
In (g), with area functional A, the initial contour is shrunk and expanded automatically to match the boundary of vessels.
Another difference in methodology between the two studies is that the organ VOIs in the current study were drawn on the anatomical images obtained from the coregistered CT images (using PET/CT), while in the Zr-/Y-ibritumomab study the images were acquired on a stand-alone PET scanner with the organs contoured on functional images.
