/*
* edtaa3()
*
* Sweep-and-update Euclidean distance transform of an
* image. Positive pixels are treated as object pixels,
* zero or negative pixels are treated as background.
* An attempt is made to treat antialiased edges correctly.
* The input image must have pixels in the range [0,1],
* and the antialiased image should be a box-filter
* sampling of the ideal, crisp edge.
* If the antialias region is more than 1 pixel wide,
* the result from this transform will be inaccurate.
*
* By Stefan Gustavson (stefan.gustavson@gmail.com).
*
* Originally written in 1994, based on a verbal
* description of Per-Erik Danielsson's SSED8 algorithm
* as presented in the PhD dissertation of Ingemar
* Ragnemalm. This is Per-Erik Danielsson's scanline
* scheme from 1979 - I only implemented it in C.
*
* Updated in 2004 to treat border pixels correctly,
* and cleaned up the code to improve readability.
*
* Updated in 2009 to handle anti-aliased edges,
* as published in the article "Anti-aliased Euclidean
* distance transform" by Stefan Gustavson and Robin Strand,
* Pattern Recognition Letters 32 (2011) 252¨C257.
*
* Updated in 2011 to avoid a corner case causing an
* infinite loop for some input data.

*
* edtaa3()
*
* Sweep-and-update Euclidean distance transform of an
* image. Positive pixels are treated as object pixels,
* zero or negative pixels are treated as background.
* An attempt is made to treat antialiased edges correctly.
* The input image must have pixels in the range [0,1],
* and the antialiased image should be a box-filter
* sampling of the ideal, crisp edge.
* If the antialias region is more than 1 pixel wide,
* the result from this transform will be inaccurate.
*
* By Stefan Gustavson (stefan.gustavson@gmail.com).
*
* Originally written in 1994, based on a verbal
* description of the SSED8 algorithm published in the
* PhD dissertation of Ingemar Ragnemalm. This is his
* algorithm, I only implemented it in C.
*
* Updated in 2004 to treat border pixels correctly,
* and cleaned up the code to improve readability.
*
* Updated in 2009 to handle anti-aliased edges.
*
* Updated in 2011 to avoid a corner case infinite loop.
