Dice coefficient between two boolean NumPy arrays or array-like data. This is commonly used as a set similarity measurement (though note it is not a true metric; it does not satisfy the triangle inequality). The dimensionality of the input is completely arbitrary, but `im1.shape` and `im2.shape` much be equal. This Gist is licensed under the mod…

| Computes the Dice coefficient, a measure of set similarity. | |
| Parameters | |
| ---------- | |
| im1 : array-like, bool | |
| Any array of arbitrary size. If not boolean, will be converted. | |
| im2 : array-like, bool | |
| Any other array of identical size. If not boolean, will be converted. | |
| Returns |
