If the number of flooded pixels lowers proportionally to boundary length across different levels of gap filling it means that most probably the boundaries of the structure in question do not have any gaps .17 Sizes of consecutive flood-filled areas are compared.

After finding the optimal number of border expansions (denoted by `GrowLevel`), the resulting region is dilated the same number of times as the boundaries were grown to make the area of the resulting path unbiased and the resulting corrected bitmap is passed to [http://potrace.sourceforge.net/ PoTrace].
