Try adapthisteq(). Try it yourself first. It will get rid of the dark background and normalize all the writing. try different parameters until you get it correct. Come back with your code if you need help.

You might try bwconvhull() on the binary image before calculating the area and perimeter. This will round out the blobs and make that bottom one have not so high a circularity.

Img(200 > Img & Img > 30) = 200;

That is probably more general than you intended, but your question was very general. What kinda functions to achieve what goal?
