assert "numBatchCalculations > 0" failed in Get()

[daviddoria]

If I fill this image: http://daviddoria.com/Uploads/ImageCompleter/input.png

with this mask: http://daviddoria.com/Uploads/ImageCompleter/mask_full.png

it works fine (the result is bad, but it runs).

However, if I use this mask: http://daviddoria.com/Uploads/ImageCompleter/mask_small.png

it crashes with:

Image Completion Using Efficient Belief Propagation There are 108 nodes. There are 0 labels. /media/portable/Projects/src/lafarren-image-completer/src/image-completer-lib/impl/EnergyCalculatorContainer.cpp(334): assert "numBatchCalculations > 0" failed in Get(). Collecting stack trace information, please wait...

This mask then works again, so there is no problem with the grey pixels: http://daviddoria.com/Uploads/ImageCompleter/mask_big.png

The problem I guess is that the patches that are being used are bigger than the white region. It would be nice for this to crash more gracefully with a " There are 0 labels!" instead of this giant assertion error.
