Object Tracking and Detection in Augmented Reality Applications

Abstract:

Object tracking for augmented reality involves determining a location of an object in a current frame (10) of a video stream based on object feature representations extracted from different locations in the current frame (10) and object feature representations belonging to a model of the object. The model comprises at least one object feature representation extracted from at least one previous frame (20) of the video stream and at least one object feature representation from a feature set comprising at least one server-generated object feature representation of objects belonging to a same object class as the object.
