Also provides the\nmedial axis transform (Blum 1967) and a distance transform\nimplementation following Felzenszwalb and Huttenlocher (2012)\n. The drop-in thinImage()\nmatches the signature of thinImage() in the 'EBImage' package\non Bioconductor so existing code can switch parsers without\nchanges.
