Pose estimation faces numerous challenges that impact accuracy and robustness. These include occlusion, where body parts are hidden by objects or people, like individuals walking behind others in crowded scenes. Variations in illumination affect visibility, such as shadows obscuring body points. Scale differences in body size and distance from the camera can distort perception. Lastly, diversity in body shapes, poses, clothing, and backgrounds complicates accurate detection. For example, loose clothing may obscure body contours, making key points harder to identify.

Pose estimation, which enhances human-computer interaction (HCI) and virtual reality (VR) applications, faces several challenges. One significant issue is the complexity of accurately detecting and tracking body movements in real-time, especially in dynamic or cluttered environments. Additionally, the technology often struggles with occlusion, where parts of the body are hidden from the camera, leading to incomplete or inaccurate data. Furthermore, ensuring high accuracy across diverse body types and movements requires extensive training data and robust algorithms, which can be computationally intensive and costly to develop. Despite these challenges, advancements continue to push the boundaries of what's possible in HCI and VR.
