Abstract

A new Euclidean distance transformation (EDT) for binary images in Zⁿ is introduced. We sequentialize the parallel method of Huang and Mitchell by restricting the propagation to sufficient propagation paths. Tests in Z² and in Z³ show that the algorithm is significantly faster than other well known signed and unsigned EDTs. Combined with the method of Saito and Toriwaki, it also yields a fast parallel EDT.
