In this document, we provide more implementation details of CATs and more results on SPair71k [16], PF-PASCAL [4], and PF-WILLOW [3]. Given resized input images Is,It R256 256 3, we conducted experiments using different feature backbone networks, including DeiT-B [22], DINO [2] and ResNet-101 [5]. For the ResNet-101multi in the paper, we use the best layer subset [15] of (0,8,20,21,26,28,29,30) for SPair-71k, and (2,17,21,22,25,26,28) for PF-PASCAL and PF-WILLOW. We resized the spatial resolution of extracted feature maps to 16 16. The extracted features undergo l-2 normalization and the correlation maps are constructed using dot products.
