Category Definitions

  • 48: type 48 containers, including 48G, 48X, and 48Y. Note that in later campaigns we explicitly distinguish among the three types.

  • background: samples that intentionally contain only background, without any cylinders.

  • synthetic: samples generated using our synthetic workflow.

Notes

There is a fairly wide range of distances from camera to cylinder, so that they do not tend to fill the frame.

Backgrounds and non-backgrounds are aligned: for all \(n\) where \(n \bmod 10 = 0\), each sample image_\(n\) with a cylinder has a matching sample background_\(n\) without a cylinder.

Questions

Why are there 624 samples without a container that are tagged “synthetic” but not “background”?

Those are scenes which contained a type 48 cylinder and would otherwise be tagged “48 + synthetic”, except that the cylinder was unintentionally off camera. So the labelling is accurate.
