Another example where blurring succeeds only partially (license plate for car in front is blurred, but car turning right has license plate fully visible): http://openstreetview.org/details/5563/337

License plate blurring seems to not work at all in my uploaded track. Though I did everything the app as recommending (i.e. recorded in landscape mode, fix focussed camera to avoid blurry pictures) the algorithm seems be totally off track with the blurring. I see fragments blurred in places where no license plate is near.

What surprised me was the detail, that after uploading the images, the images were in wrong orientation, I needed to apply a 90 degree rotation to them to make them landscape in the webpage.

It looks like image orientation info is not correctly analyzed on the server side, which may lead to the mismatches in blurring (blur-algo calculating on portrait, while pictures are landscape).

Working on an enhanced blurring model. Will follow up with deets once deployed.
