3D Object Instance Re-Localization

Tags: computer-vision | Paper

This is an odd one but probably important to someone. Suppose that you can compute a 3D object instance segmentation. I.e. you can locate where an object is in 3D. Then, given a different view of the scene, can you find the objects again? This is important, probably, because succeeding at the instance segmentation at arbitrary views of the scene is harder, you might think, then if you use your prior knowledge about the objects positions, having seen them before.

For me this is an interesting work related to the general idea of “temporal coherence”; i.e. using knowledge that we know from a previous timestep at a new timestep.
