If you do not mind that the result is going to be majorly different -

*I* think that for best result, one needs an additional *relative*
threshold.  E.g., if main threshold is 12, and relative is 30%, then
one would skip pixels which differ from a preceeding one by less than
about 4.

If this relative threshold is close to 100% (which is essentially what
you recommend), then the result will be quite different comparing to
one with low threshold.
