Base class for KLMSegmentationRegion object.
itkKLMSegmentationRegion is the base class for the KLMSegmentationRegion objects. It provides the basic function definitions that are inherent to KLMSegmentationRegion objects.
This object supports data handling of multiband images. The object accepts images in vector format, where each pixel is a vector and each element of the vector corresponds to an entry from 1 particular band of a multiband dataset.
We expect the user to provide the input to the routine in vector format. A single band image is treated as a vector image with a single element for every vector.
Data structure for a region: A region is defined as a closed area in the image that is surrounded by a list of borders objects (see itkKLMSegmentationBorder class).
Shown below is an initial two-dimensional 8x9 image with a 4x3 grid size partition. The initial region blocks are labelled in hexadecimal. Below the grid partition, the borders are shown as E, where C is an image pixel from the initial image. Note that each border is placed in between two regions. Each two-dimensional region is surrounded by four borders.
Initial regions of a 8 by 9 image with a 4 by 3 grid partition.
\[\begin{tabular}{|c|c|c|c|c|c|c|c|c|} \hline 1 & 1 & 1 & 2 & 2 & 2 & 3 & 3 & 3 \\ \hline 1 & 1 & 1 & 2 & 2 & 2 & 3 & 3 & 3 \\ \hline 4 & 4 & 4 & 5 & 5 & 5 & 6 & 6 & 6 \\ \hline 4 & 4 & 4 & 5 & 5 & 5 & 6 & 6 & 6 \\ \hline 7 & 7 & 7 & 8 & 8 & 8 & 9 & 9 & 9 \\ \hline 7 & 7 & 7 & 8 & 8 & 8 & 9 & 9 & 9 \\ \hline a & a & a & b & b & b & c & c & c \\ \hline a & a & a & b & b & b & c & c & c \\ \hline \end{tabular}\]
Region borders are shown as "E".

Set the region with parameter values defining the region.
void itk::KLMSegmentationRegion::SpliceRegionBorders | ( | Self * | region | ) |
Splice the regions borders from the new region into the current region. If duplicate borders are found, the duplicate border region is not inserted into the new region borders list, rather, it has its pointers to region1 and region2 set to nullptr and Lambda set to -1.0.
For example, take an image with 3 regions A, B, C
\[\begin{tabular}{|c|c|} \hline A & A \\ \hline B & C \\ \hline \end{tabular}\]
where region A has region borders A-B and A-C; region B has region borders A-B and B-C; and region C has region borders A-C and B-C.
Suppose region border A-B has been removed, so that region B can be merged into region A. When splicing the region borders from A and B into the new region A, duplicate region borders A-C and A-C (one of which was formerly B-C) will be present. In this case, one of the region borders A-C is given the combined length of the two former borders and is put into the region borders list. The other is nullified by having its pointers to region1 and region2 set to nullptr and its Lambda value set to -1.0.
void itk::KLMSegmentationRegion::UpdateRegionBorderLambda | ( | ) |
Recalculate the Lambda values using EvaluateLambda() for all the borders defining the region.
