Usage: nbcomp in.pgm connex {fgd|bgd|min|max|pla} [out.list]

Description: The argument connex selects the connectivity (4, 8 in 2D; 6, 18, 26 in 3D). The argument <min|max|pla> selects the kind of flat zone to be counted:

• fgd selects foreground components for a binary image

• max selects regional maxima
• pla selects all flat zones (plateaux).

The result is written in the list out.list.

If the parameter out.list is ommitted, the result is printed on the standard output.
