Detailed Description

ultimate constrained collapse guided by a priority image

Usage: 2dcollapse in.pgm prio [inhibit] out.pgm

Description: Ultimate constrained collapse guided by a priority image. The lowest values of the priority image correspond to the highest priority.

The parameter prio is either an image (byte or int32_t), or a numerical code indicating that a distance map will be used as a priority image; the possible choices are:

• 0: approximate euclidean distance
• 1: approximate quadratic euclidean distance
• 2: chamfer distance
• 3: exact quadratic euclidean distance
• 4: 4-distance in 2d
• 8: 8-distance in 2d

If the parameter inhibit is given and is a binary image name, then the elements of this image will be left unchanged. If the parameter inhibit is given and is a number I, then the elements with priority greater than or equal to I will be left unchanged.

Warning:

The result makes sense only if the input image is a complex.
