Comments:
The class IndexNeigh2dC represents a set of 2D indexes in a neighborhood of a pixel.

IndexNeigh2dC n8;

8 connected neighborhood.

IndexNeigh2dC n4;

4 connected neighborhood.

IndexNeigh2dC boundaryInfluence;

The neighborhood of pixels that can be influented by the fast change of input sensor signal.

GridDistanceT dist;

maximum distance

GridMetricT type;

type of the metric

SizeT sizeR;

number of rows of the 'index' array

SizeT sizeC;

number of columns of the 'index' array

IndexT offsetR;

row offset of the 'index' array

IndexT offsetC;

column offset of the 'index' array

SizeT elms;

number of indexes in the neighbourhood

IndDistT * neighbour;

indexes of the neighbourhood ordered according to distance

IndexT ** index;

mapping from an index into its rank.

IndexRangeC * ranges;

mapping from distance into the rank of elements

IndexNeigh2dC(GridDistanceT maxDistance = 5,GridMetricT metric = CITY_BLOCK)

Creates the set of relative indexes which belongs to the neighbourhood determined by 'distance' using the 'metric' of grid.

IndexNeigh2dC(SizeT elementNumber,Index2dC * indexes,GridMetricT metric = CITY_BLOCK)

Creates the set of relative indexes from the array of 'indexes' which number of elements is determined by 'elementNumber'. The metric is defined by variable 'metric'.

IndexNeigh2dC(const SArray1dC<Index2dC> & arr,GridMetricT metric = CITY_BLOCK)

Creates the set of relative indexes from the array of 'indexes'. The metric is defined by variable 'metric'.
