Binary morphological opening operation
#include "dip_binary.h"
dip_Error dip_BinaryOpening ( in, out, connectivity, iterations, edge )
binary
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). Additionally, you can set it to -1 for special handling: DIP_TRUE for the erosion, DIP_FALSE for the dilation; this avoids the border effect you can get in the corners of the image in some cases.
See section 9.6, "Morphology-based operations", in Fundamentals of Image Processing for a description of binary mathematical morphology operations.
