Fix anchor for small symmetrical column filters.
...
In the unoptimized version of small symmetrical column filters, when we
try to detect if the kernel, ky, is equal to [1;2;1] or [1;-2;1] we
should take into consideration that the anchor points in the middle
element.

Otsu's method. Triangle deals better with images whose histogram does not
contain dominant peak.
