External exemplars

[GioFic95]

Hi @Verg-Avesta, is it possible to make inference providing exemplars which are not part of the input image? That is, I would like to select k exemplars from the first of n images composing my test dataset, and then use the same k crops from the first image for all the n queries, given that the objects are of the same class across the whole dataset.

Is this possibility already available and implemented somewhere? Thank you in advance.
