I find that the traffic sign detection sometimes mis-detects the signs, for instance, a weight limit sign being detected as a speed limit sign.
Would it be possible to have some way of flagging incorrect sign detections, so that any machine vision systems can be retrained?
An example. in the UK: weight limit sign being detected as a speed limit sign. They’re both white circular signs with a red border, both of them start with a black numeral, but a 5 tonne limit sign has the letter T
I’d expect a signed-in user to be able flag a traffic sign detection as a different category of traffic sign, or not a traffic sign at all. (I’ve seen car wheels detected as height restrictions)
I would like to see something like “edit blurrs on this image”, but instead “edit signs on this image”. Both a way to delete sign detections entirely, and to re-tag the sign to a correct value.
I often see signs detected incorrectly and think it would be a good opportunity to fix them and help the algorithm. As this post is >1y/o, has there been any progress on this issue or have I missed it?
Thanks!
Hey @Thibaultmol, just responded to your Tweet, but for now, we only have an internal tracker for reports of incorrect detentions. It’s been discussed for a while (as you can see!) to have this made public, but until it is, you can send them to me at support@mapillary.com and I’ll report them for you to the Vision team.
