now we use filesize to find empty tiles, we need to use histograms in the future.

Adaptive thresholding is probably what we want. Look at: http://www.imagemagick.org/discourse-server/viewtopic.php?f=1&t=8285&start=0 for further info. http://www.multipole.org/discourse-server/viewtopic.php?f=1&t=11297 use -normalize

CellProfiler does a better job finding tissue. No need to do this when checking for empty tiles.
