BinaryErosion

Binary morphological erosion operation

SYNOPSIS

#include "dip_binary.h"

dip_Error dip_BinaryErosion ( in, out, connectivity, iterations, edge )

DATA TYPES

binary

FUNCTION

The connectivity parameter defines the metric, that is, the shape of the structuring element. 1 indicates city-block metric, or a diamond-shaped structuring element. 2 indicates chessboard metric, or a square structuring element. -1 and -2 indicate alternating connectivity and produce an octagonal structuring element. See The connectivity parameter for more information. The edge parameter specifies whether the border of the image should be treated as object (DIP_TRUE) or as background (DIP_FALSE).

See section 9.6, "Morphology-based operations", in "Fundamentals of Image Processing" for a description of binary mathematical morphology operations.
