Detailed Description

converts a 2D image into a 2D Khalimsky order

Usage: 2dkhalimskize in.pgm {0|4|8|h|m|M|g|G|a} out.pgm

Description: Converts a 2D image into a 2D Khalimsky order, or conversely.

Modes 0, 4, 8 and h are for binary images.

Modes m, M, g, G and a are for grayscale images.

Mode =

• 0 : only maximal elements,
• 4 : emulates 4-connectivity, idem "miss",
• 8 : emulates 8-connectivity ("hit" transform followed by a kernel transform),
• h : "hit",
• m : min,
• M : max,
• g : gradient 2,
• G : gradient 4,
• a : average,
• R : reverse.

In reverse mode (R), only the beta-terminal elements (squares) are selected.

Types supported: byte 2d, long 2d, float 2d
