You don't need a fancy tissue detector for slides. I would just take
the histogram of each area and see if you have more than a few % of
non-white pixels.

As Mark says, start with the low-res levels and refine.

I've always just found the histogram and calculated the entropy. It's
easy to make a nice, normalized 0 - 100 number, and its very robust.
Again, you don't need anything fancy for slides.
