Detailed Description

Image Neighborhood definition.

The Neighborhood is usually meant to select a sub-population from the input Data Base, containing the active samples close to the target.

This Neighborhood is only defined in the case when the Data and the Target belong to the same grid. This neighborhood is defined as a rectangular set of pixels, located around the target. This rectangle is given by its half-extension in each space dimension (called 'radius') As the number of pixels grows fast with the space dimension, it is offered to sample them by specifying a skipping factor, so as to retain only 1 / (1 + skip) of them.
