On efficient multi-angle face prototype collection

Although extremely tedious, collecting multi-angle face prototypes is essential for face-related applications such as detection, tracking, recognition, and pose estimation. To reduce the load, we propose a user-friendly interface that is designed to collect multi-angle face prototypes in a fast and easily tractable manner. A user-friendly interface called dynamic cursor is designed to guide users' viewing directions for orientation-enforced video acquisition. A new problem called the orientation-enforced face detection problem is proposed and solved for multi-angle face prototype collection. Our method can help build a fast and user-friendly face registration module for face-related applications.
