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 55018 background samples, instead of 55000?
We accidentally created a few extra background samples, and saw no reason to discard them.
What are the 133 samples tagged “synthetic”?
Those are scenes which contained a type 48 cylinder which would otherwise be tagged “48 + synthetic”, except that the cylinder was unintentionally off camera. So the labelling is accurate.
