+This repository contains the implementation of our method for estimating correspondences with Stable Diffusion in an unsupervised manner. Code for getting the attention maps has been modified from [Prompt-to-Prompt](https://github.com/google/prompt-to-prompt/) and the dataloader for the Spair-71k and PFWillow datasets has been modified from [Cats++](https://github.com/KU-CVLAB/CATs-PlusPlus). Our new method surpasses weakly supervised methods and closes the gap to strongly supervised methods.
