pub enum Norm {
L1,
LInf,
}Expand description
How to measure distance between coordinates.
See the distance_transform documentation for examples.
Note that this enum doesn’t currently include the L2 norm. As Norm
is used by the morphology functions, this means that we
don’t support using the L2 norm for any of those functions.
This module does support calculating the L2 distance function, via the
euclidean_squared_distance_transform
function, but the signature of this function is not currently compatible with those for
computing L1 and LInf distance transforms. It would be nice to unify these functions
in future.
Variants§
L1
Defines d((x1, y1), (x2, y2)) to be abs(x1 - x2) + abs(y1 - y2). Also known as the Manhattan or city block norm.
LInf
Defines d((x1, y1), (x2, y2)) to be max(abs(x1 - x2), abs(y1 - y2)). Also known as the chessboard norm.
