models used:

• bbox detector for finding clock face in the image
• classifier for clock orientation estimation
• keypoint detection for center and top
• semantic segmentation for finding clock hands
• KDE for splitting the binary segmentation mask into individual clock hands

Watch crop with center and top keypoint
