Hmm. These are quite interesting, line drawing style. Does "low black" just mean biasing the threshold in the adaptive thresholding, or is there something else going on?
Does the adaptive threshold make use of the width of the local histogram? (variance if no histograms used.) I think, no. This would be a useful parameter for us: bias up in cases where the area is dark and the histogram narrow, bias down in light low-variance areas.
