+# ID-Pose: Sparse-view Camera Pose Estimation by Inverting Diffusion Models

+## Abstract
+- ID-Pose estimates camera poses of sparse-view images of a 3D object (appearance overlaps not required).
+- ID-Pose inversely uses the off-the-shelf Zero123 to estimate camera poses by iteratively minimizing denoising errors given input images.
+- ID-Pose is a zero-shot method that requires NO additional model training or finetuning.
+- ID-Pose exhibits strong generalization ability on open-world images as the method effectively leverages the image priors from Zero123 (StableDiffusion).
