## Overview

UniCorrn is the first correspondence model with shared weights that unifies 2D-2D, 2D-3D, and 3D-3D geometric matching with an end-to-end transformer architecture.

This model space contains the large-scale pretrained weights from Stage 1 and Stage 2 training, as well as a modified version of the CroCoV2 weights adapted to match our model attributes.
