Hi, is it possible to get several photos of the place without any car?

One way I've tried to get around this is to invert the mask, and then take the difference of the 16 images for a given car. This has the net effect of rotating the background 360 degrees and what you're left with is the background and the minimum car mask that has an overlap only where the car exists in all 16 images. \nYou could extend the concept to all cars. Be careful though, I believe there are three different backgrounds.\nHere's an example of what I mean for just one car rotated.
I was able to dig up one photo from a couple of years ago. I will need to discuss with the Kaggle team how to release it fairly.
\n\nIt's important to note that there are multiple physical locations, so one reference frame will not align perfectly all photos. Occasionally, when a studio is serviced, things like the paint on the floor, camera's position, and lighting color temperature can change slightly.
