Category Definitions
30B: type 30B cylinders.
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
What happened to Campaign 1?
Campaign 1 was for development and debugging of our synthetic workflow.
Why are there 54999 samples, instead of 55000?
We discovered that one output sample had garbled cryptomatte data, so we deleted it.
Why are there 932 samples without a container that are tagged “synthetic” but not “background”?
Those are scenes which contained a type 30B cylinder which would otherwise be tagged “30B + synthetic”, except that randomly-chosen camera angle put the cylinder off-screen. So the labelling is accurate.
