I don't like having background == 0, but I'll settle for background == -1 as a default.

Thanks!

Please review the PR at: https://github.com/scikits-image/scikits-image/pull/105

Or, len(np.unique(labels)) - 1, if we do not count the background in.

Or, as Tony mentioned: labels.max() Cheers Stéfan
