[SciPy-user] Explanation of different edge modes in scipy.ndimage
Fri Oct 31 12:09:59 CDT 2008
I'm doing some gaussian filtering of periodic 2D arrays using
scipy.ndimage.gaussian_filter. There is a 'mode' argument that is set to
'reflect' by default. In _ni_support.py:34 there is a conversion function,
'_extend_mode_to_code' that gives the different modes available. For
periodic data I believe I should use 'wrap', but I'm interested to know what
the other modes mean, esp the difference between 'reflect' and 'mirror'.
For the record, the modes defined are 'nearest', 'wrap', 'reflect',
'mirror', and 'constant'. For future reference, is there a place where
these arguments are documented?
