Abstract: Methods and systems for presenting imagery associated with a geographic location to a user include providing at least one geographic map or panoramic imagery to a client for display in an interface configured for interactive navigation of the at least one geographic map or panoramic imagery, receiving a user selection collected by the interface indicating a location corresponding to the at least one geographic map or panoramic imagery, identifying a plurality of images associated with the received user selection, obtaining at least one user preference associated with the identified images, ranking the identified images based on at least one of the retrieved user preferences, and providing at least one ranked image for display in the interface, in accordance with the ranking.

Abstract: A method of tracking an object in an input image stream, the method comprising iteratively applying the steps of: (a) rendering a three-dimensional object model according to a previously predicted state vector from a previous tracking loop or the state vector from an initialization step; (b) extracting a series of point features from the rendered object; (c) localizing corresponding point features in the input image stream; (d) deriving a new state vector from the point feature locations in the input image stream.

Abstract: The invention relates to the application area of camera-based head and eye tracking systems. The performance of such systems typically suffers when eye glasses are worn, as the frames of the glasses interfere with the tracking of the facial features utilized by the system. This invention describes how the appearance of the glasses can be utilized by such a tracking system, not only eliminating the interference of the glasses with the tracking but also aiding the tracking of the facial features. The invention utilizes a shape model of the glasses which can be tracked by a specialized tracker to derive 3D pose information.
