Choose a correct bubble threshold. #10

The bubble threshold is creating a problem. A bubble_thresh for one is not working for other. Take a look at images. The threshold is working for test-2 but not for test-3.

This issue was solved by resizing the image to h=1500. Actually compressing the image was causing details to be lost.
