In this submission, CNOS_fastSAM [A] detections (default detections for Task 4) are used as input to the MegaPose pose estimation method [B].

For each detection, we run the MegaPose coarse network and refine the 1-best coarse estimate with 5 refiner iterations.

The following improvement has been made over the original MegaPose paper [B]:
- The orientation of the coarse hypotheses are obtained my discretizing SO(3) in 576 values using [C].

Instructions to reproduce these results will be made available on https://github.com/agimus-project/happypose.
