I did a lot of capturing during the last weeks. I go through each published sequence and verify that blurring is ok. Doing this, I noticed recurring blur failures that could probably be solved by software and so make life easier for contributors and Mapillary better respect privacy:
I find road signs being blurred like big green ones on highways.
But the most common blur I see that isn’t needed are shadows under trees and certain patterns such as fences and roofing on houses.
