STEP 1: demarcation

we have the demarcation image

---

STEP 2: get an image and resize it

the image is by resize the screen region, we compare it with the orignal one, we can say, it well enough
the ssim value of the two images is 0.886242935676, very similar.

---

STEP 3 - 4: we repeat the step 2 to get another two images

---

STEP 5: now we have 3 resized images, and all they have a BAD AREA, we can get it!
