What is Oracle referred in Pixloc paper? #22

PixLoc, trained on MegaDepth, is initialized with image retrieval obtained with either DenseVLAD [88] or an oracle, which returns the reference image containing the largest number of inlier matches found by hloc. This oracle shows the benefits of better image retrieval using a more complex pipeline without ground truth information.

Doesn't the passage that you quote answer your question?

The oracle can be enabled by adding the flag refinement.do_inlier_ranking=true to the command line: https://github.com/cvg/pixloc/blob/master/pixloc/localization/refiners.py#L61
