Detailed Description

morphological binary closing by a ball

Usage: closeball in.pgm r [dist] out.pgm

Description: The closing consists in a dilation (dilatball) followed by an erosion (erosball). The structuring element for this closing is a ball (or a disc) of radius r. The erosion and dilation are computed by thresholding a distance map. The distance used depends on the optional parameter dist (default is 0) :

0: approximate euclidean distance
2: chamfer distance
4: 4-distance in 2d
8: 8-distance in 2d
6: 6-distance in 3d
18: 18-distance in 3d
26: 26-distance in 3d

Warning:: The input image in.pgm must be a binary image. No test is done.

Types supported: byte 2D, byte 3D
