Detailed Description

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. It is templated over the type of input and output image.

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 structures 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 4x3 grid size partition of a 8x9 image. The initial region blocks are labeled in hexadecimal, and the region borders are shown as E = border pixel, and C = non-border pixel. Note that the border pixel grid is one pixel larger than the region grid. The border pixel grid can be considered to lie interspersed within the region pixel grid with four border pixels surrounding each interior region pixel.
