Moreover, conventional feature encoders are typically trained on single-view 2D images, limiting their capacity to capture 3D-aware correspondences. In this paper, we propose a novel two-stage framework that lifts 2D images to 3D space, named as \\textbf{Lift to Match (L2M)}, taking full advantage of large-scale and diverse single-view images.
