Detailed Description

N-Ring neighborhood masks with prime directions.

The neighborhood is implemented for 0 ≤ n ≤ 7.

Member Function Documentation

Length()

double MaskNext::Length ( int e )

static

Return the length of the edge of the mask.

Parameters

e	Edge, should be in [0, n[ where n = MaskNext::Size(m) is the size of the maks.
