skel_dyer
skeletonizes an image as described by Dyer & Rosenfeld in 1979.
The program will skeletonize the bright coloured parts in the image.
The
input-file
should be a
.pgm
image file. If an
output-file
is specified this file will be used to store the resulting image.
Otherwise the result is written to the
input-file.
- -r
- Reverse the image during the process, resulting in the skeletonization
of the dark parts of the image instead of the bright parts.
- -n<nr>
- This option forces the program to stop after <nr> passes.
The default value is after 10000 passes.
- -q<fraction>
- This option forces the program to stop if less than <fraction>
pixels have been changed during the last pass.
The default value is 0.01.
The -n and the -q option can be used together.
- -k<factor>
- With this option the k-parameter used in the algorithm can be
set. The value of k will be set equal to 1/<factor>.
The default is -k8 (k = 0.125).
