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: rounded euclidean distance
- 2: chamfer distance
- 3: exact quadratic euclidean 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: binary byte 2D, byte 3D
