[PDF] 2D Euclidean distance transform algorithms: a comparative - CORE

Various metrics, in addition to the Euclidean, can be used to compute the distance in Equation (1) Frequently used examples are the city-block (d1) and chessboard (d∞), defined by: d1(x, y) = x1 − y1+x2 − y2 d∞(x, y) = max{x1 − y1, x2 − y2} These metrics are less costly to compute than the Euclidean metric
