How to be more robust on sky region where there is less patern

[lingjiankong]

Hi guys. Thanks for the awesome library. It has been working great.

On regions such as the sky, the disparity can be very noisy. My questions are

1. Are there any parameters that we can tweak to get more robust detection on sky where there is virtually no pattern? Ideally we want to output disparity values of 0 on sky.
2. Are there any ways to get the confidence map for disparity so that we can post filter ourselves?

Thanks!

You can play with the uniqueness parameter. Try setting it to 0.8 or so.
