说明： 目前效率最好的距离变换算法，距离变换广泛应用于图像处理，比如可以用距离变换准确找到图像中物体的骨架或者中心线。（用winrar解压）

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
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.
