Details:

When the input has blanks but the labeled image doesn't (or has blanks in
other places), the inconsistency between the two can cause a crash, something
like this:


astsegment: a bug! Please contact us at address@hidden to fix it. 1
pixels of detection 1 have not been labeled (as an object)


This is because on the labeled image pixels may be connected, but when
accounting for the blank pixels of the input, they maybe separate regions.

I am now busy implementing a fix to this problem.
