performance for moving objects

[waveleaf27]

I re-ran this project, but the performance for moving objects didn't meet expectations. Please refer to the attached figure for reference.

In the figure: (segment-10335539493577748957_1372_870_1392_870_with_camera_labels/0000_0001.npz)

Black represents points at time T.
Blue indicates points at time T+1.
Red denotes points from time T after adding the predicted flow.
As evident, the objects within the bounding box are misaligned. I've observed this issue in multiple case. Is this discrepancy expected?

Can you provide your NSFP++ baseline since it adopt extra assumption

Hi @waveleaf27, this might happen when the grid cell size is relatively large, making the prediction prone to similar motions nearby.
Please refer to MBNSF for the implementation of NSFP++ baseline.
Cheers.
