Implementation of the distance transform algorithm described in:
Distance Transforms of Sampled Functions
Pedro F. Felzenszwalb and Daniel P. Huttenlocher
Cornell Computing and Information Science TR2004-1963
http://people.cs.uchicago.edu/~pff/dt/
The main program "dt.cpp" computes the standard distance transform of
a binary image. The algorithm for computing the transform of a
sampled function is in "dt.h".
1) Type make to compile "dt".
2) Run "./dt input.pbm output.pgm" to compute the distance transform
of a binary image. The input is a binary PBM image and the output is
a grayscale PGM image. Note that the actual distance values are
scaled to fit in the [0-255] grayscale range.

Dear Olaf,
I am glad to hear the code is being used in your software and I am
happy to release it under the GPL.
Do you need me to send you anything in particular?
Pedro
