Thanks for the kind words!

We hope that the algorithm we presented is a step in the right direction, and we acknowledge that there's more work to be done! Just like with any algorithm there are ways in which it can be improved. Please check out the supplementary materials [1], to find some examples that can definitely be improved: small faces and small text. Overall, as you say, the algorithm does a great job though!
