Abstract: A landmark detection system can more accurately detect landmarks in images using a detection scheme that penalizes for dispersion parameters, such as variance or scale. The landmark detection system can be trained using both labeled and unlabeled training data in a semi-supervised approach. The landmark detection system can further implement tracking of an object across multiple images using landmark data.

Abstract: A wrist tracking process is provided for use in Augmented Reality (AR) applications. A computing system captures video frame tracking data of a wrist of a user and generates 3D parameter data of the user's wrist based on the video frame tracking data. The computing system generates 3D render data of a virtual item based on the 3D parameter data of the user's wrist, and 3D model data of a physical item represented by the virtual item. The computing system generates video frame AR data based on the 3D render data and the video frame tracking data. The computing system provides an AR user interface to the user based on the video frame AR data.
