clarification on object-se

[monajalal]

Could you please clarify what is "TWO" here since there is only one barbecue sauce here

[{"label": "barbecue-sauce", "TWO": [[0.5436763454963882, 0.622191933760276, -0.4349827125343375, 0.3578873048305161], [0.1073753759264946, 0.07318738847970963, 0.4580722153186798]]}]

Also,

If there are two detected objects, why one has an array of size 4 and the other has an array of size 3?

Thanks

Hi @monajalal, I believe TWO is specific to CosyPose/MegaPose and not related to the HOPE dataset. Given that it's a length-4 vector and a length-3 vector, it might be a pose expressed as [[quaternion], [translation]]. But that's only a guess without looking at the code.
