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:
- Blurring of license plates that are perfectly readable fails when character size is below a certain size, example. I blurred the plate of the car on the right manually, but you can still decode the plates of the three cars in the middle.
- It seems to me that license plates that are not horizontal are not recognized and blurred, example ( I blurred the plate manually)
- From time to time I fall upon cases where a traffic sign is blurred but well detected by the traffic sign detection software. I understand that blurring and sign detection are two independent processes but it would be nice to have some interconnection.
