Fig. 4: Representative examples comparing our method and SuperGlue on two complementary tasks.

Homologous Rubbing Alignment(i.e., identifying the rank of correct matching pair from a large candidate set) and Single Rubbing Retrieval(i.e., the left image is treated as a query, and the rank denotes the position of its corresponding right image within the retrieved list).In our method, the red connected points represent correctly matched OBIs, while in SuperGlue, they indicate successfully matched feature points. a Examples where our method outperforms SuperGlue in both alignment and retrieval. b Examples where SuperGlue outperforms our method in both alignment and retrieval. The comparison highlights the complementary nature of the two methods.
