Module windowdiff'

Compute the windowdiff score for a pair of segmentations. A segmentation is any sequence over a vocabulary of two items (e.g. "0", "1"), where the specified boundary value is used to mark the edge of a segmentation.

>>> s1 = "00000010000000001000000"
>>> s2 = "00000001000000010000000"
>>> s3 = "00010000000000000001000"
>>> windowdiff(s1, s1, 3)
0
>>> windowdiff(s1, s2, 3)
4
>>> windowdiff(s2, s3, 3)
16

Parameters:

• seg1 (string or list) - a segmentation
• seg2 (string or list) - a segmentation
• k (int) - window width
• boundary (string or int or bool) - boundary value

Returns: int
