Segmentation, Binarization. A two-class technique which assumes the only alternative is to find
a single threshold. Find points with high gradients, grow regions
which have similar values. Essentially finds multiple thresholds
for different characters (character extraction experiments).

Segmentation, Binarization. The threshold is selected on small windows (size depends on
differences) without using the histogram computation. It seems to
say that it is relevant only for the two class segmentation
problem. Some of the ideas could be applied to a general
histogram based segmentation scheme.
