Test images from "Structure-Aware Halftoning" by Pang et. al

Compared with those results in the paper, even there are not much percentage pixels used in our tree result, it looks not worse than their result. (After scaling it and looking at it again, I have to say it is worse than their result.) Our result for the cat example looks worse than their result. But the good thing is that at least our method did not destroy the structure for the cat a lot. Size(440 by 373)
