from depixelizer import Depixelize
Depixelize(input_image_path, output_dir).run()

???

Seems to get stuck in an infinite loop?
The original Microsoft research paper mentions sub second run times to process an image.
But this code runs for minutes at 100% CPU, and when I stop the script, this is the call stack I see:

$ time ./depixel_png.py --to-svg bt_02.png
Processing bt_02.png...

Thanks for making this library! It seems to be very useful for me but I'm not sure how to get started after installing and running the test cases.
Is there any chance that you provide some simple examples for beginners to get started?
That would be very helpful. Thank you!
