3D Hand Pose Estimation

3D hand pose estimation is an important subtask in the field of computer vision, aiming to accurately recover the position and posture of the hand in 3D space through image or video data. The goal of this task is to achieve high-precision detection and tracking of hand keypoints to support applications such as human-computer interaction, virtual reality, and gesture recognition, enhancing the naturalness and user-friendliness of the system.
