scipy.spatial.distance.dice¶
- scipy.spatial.distance.dice(u, v)[source]¶
Computes the Dice dissimilarity between two boolean 1-D arrays.
The Dice dissimilarity between u and v, is
where
is the number of occurrences of
![\mathtt{u[k]} = i](../_images/math/1f2e6ebb7498423654e0ce52676dc669d0309ce9.png)
and ![\mathtt{v[k]} = j](../_images/math/ca0752041eb1e05ca2b4bb35a62412b5bdad9c32.png)
for
.Parameters : u : (N,) ndarray, bool
Input 1-D array.
v : (N,) ndarray, bool
Input 1-D array.
Returns : dice : double
The Dice dissimilarity between 1-D arrays u and v.
