• EventGeM uses a pre-trained vision transformer (ViT-S/16) backbone for initial global feature matching.method 70%
  Evidencepartial

  We use a pre-trained vision transformer (ViT-S/16) backbone to obtain global feature patch for initial match predictions embeddings from event histogram images.

  Implicationpartial

  The abstract clearly describes the role of the ViT-S/16 backbone in the pipeline.

• A pre-trained vision foundation model for depth estimation is used for additional re-ranking refinement.method 70%
  Evidencepartial

  For additional re-ranking refinement, we subsequently used a pre-trained vision foundation model for depth estimation to compare structural similarity between references and queries.

  Implicationpartial

  The abstract explicitly mentions the use of a depth estimation model for refinement.
