The length of the filter depends on the character of the noise model and the size of
the patch. We found that, for matching the multiples, short filters (2 to 4 samples
in each axes) worked well but for the ground-roll example a longer filter gave
better results (27 samples in time and 2 in offset) because the nature of the noise
and the signal were so different.
