Confusing mask result for dynamic objects

[irwinherrmann]

Hi,

Thanks for the great work!

I'm a bit confused by the flow and flow mask for: ocean/Easy/P012/image_left/000367_left.png

The mask doesn't seem like it's correctly highlighting the dynamic object.

Im0

Im1

Flow

Warp of Im1 to Im0 through Flow

Mask == 1

Mask == 10

Mask == 100

Also, would it be possible to get a pointer to the mask generation code?

Thanks!
Charles

+1 to @irwinherrmann's comment. This seems like a hard problem to me unless there is flow available from the rendering engine itself as discussed here. I was wondering if you can provide insights on which environments have dynamic objects and which don't. Also the paper talks about an ablation in Table V where you turn off dynamic objects. I wonder if such a version of the dataset can be made available if it is hard to reliably mask out dynamic objects. Thanks again for this amazing work!
