| # Pose Anything Demo | |
| We present a novel approach to category agnostic pose estimation that | |
| leverages the inherent geometrical relations between keypoints through a | |
| newly designed Graph Transformer Decoder. By capturing and incorporating | |
| this crucial structural information, our method enhances the accuracy of | |
| keypoint localization, marking a significant departure from conventional | |
| CAPE techniques that treat keypoints as isolated entities. | |

| ## Instructions | |
| 1. Upload an image of the object you want to pose on the **left** image. | |
| 2. Click on the **left** image to mark keypoints. | |
| 3. Click on the keypoints on the **right** image to mark limbs. | |
| 4. Upload an image of the object you want to pose to the query image ( | |
| **bottom**). | |
| 5. Click **Evaluate** to pose the query image. | |
