20110115671 | DETERMINATION OF ELEVATION OF MOBILE STATION - A mobile station determines it elevation based on the determined position of mobile station and a database of elevation data. The determined elevation of the mobile station may be used to vertically position a computer generated graphics in an image produced by the mobile station. In one embodiment, the elevation of the mobile station is determined by obtaining the elevation of multiple positions that define an area around the mobile station and using the elevation at the multiple positions to calculate the elevation at the current position. | 05-19-2011 |
20120062702 | ONLINE REFERENCE GENERATION AND TRACKING FOR MULTI-USER AUGMENTED REALITY - A multi-user augmented reality (AR) system operates without a previously acquired common reference by generating a reference image on the fly. The reference image is produced by capturing at least two images of a planar object and using the images to determine a pose (position and orientation) of a first mobile platform with respect to the planar object. Based on the orientation of the mobile platform, an image of the planar object, which may be one of the initial images or a subsequently captured image, is warped to produce the reference image of a front view of the planar object. The reference image may be produced by the mobile platform or by, e.g., a server. Other mobile platforms may determine their pose with respect to the planar object using the reference image to perform a multi-user augmented reality application. | 03-15-2012 |
20120218456 | AUTO-FOCUS TRACKING - An apparatus and method for supporting augmented reality or other computer vision applications are presented. Embodiments enable communication between natural feature and auto-focus engines to increase an engine's accuracy or decrease a processing time of the engine. An auto-focus engine may communicate a location of an auto-focus window to a natural feature detection module and/or a change in location of a previous auto-focus window to a next auto-focus window. The natural feature detection module uses the communicated information to limit an initial search area and/or to set a next tracking search window. A natural feature tracking module may communicate a changes from a previous location of a natural feature to a next location of the natural feature to an auto-focus engine. The auto-focus engine uses the change to set a next auto-focus window. | 08-30-2012 |
20120224068 | DYNAMIC TEMPLATE TRACKING - Various arrangements for tracking a target within a series of images is presented. The target may be detected within a first image at least partially based on a correspondence between the target and a stored reference template. A tracking template may be created for tracking the target using the first image. The target may be located within a second image using the tracking template. | 09-06-2012 |
20120224773 | REDUNDANT DETECTION FILTERING - Systems and methods are described herein for identifying and filtering redundant database entries associated with a visual search system. An example of a method of managing a database associated with a mobile device described herein includes identifying a captured image; obtaining an external database record from an external database corresponding to an object identified from the captured image; comparing the external database record to a locally stored database record; and locally discarding one of the external database record or the locally stored database record if the comparing indicates overlap between the external database record and the locally stored database record. | 09-06-2012 |
20120269388 | ONLINE REFERENCE PATCH GENERATION AND POSE ESTIMATION FOR AUGMENTED REALITY - A reference patch of an unknown environment is generated on the fly for positioning and tracking. The reference patch is generated using a captured image of a planar object with two perpendicular sets of parallel lines. The planar object is detected in the image and axes of the world coordinate system are defined using the vanishing points for the two sets of parallel lines. The camera rotation is recovered based on the defined axes, and the reference patch of at least a portion of the image of the planar object is generated using the recovered camera rotation. The reference patch can then be used for vision based detection and tracking. The planar object may be detected in the image as sets of parallel lines or as a rectangle. | 10-25-2012 |
20120329432 | RELEVANT CONTENT DELIVERY - Various arrangements for delivery of relevant content to a mobile device of a user are presented. Physiological state data and image data related to the user of the mobile device may be received by a host computer system from a mobile device. The image data may be analyzed to identify a characteristic of the image. The physiological state data may also be analyzed. Content to deliver to the mobile device of the user may be selected at least partially based on the physiological state data of the user and the characteristic of the image. The content may be transmitted to the mobile device. | 12-27-2012 |
20130194438 | SMART CAMERA FOR SHARING PICTURES AUTOMATICALLY - Embodiments of the invention disclose methods, apparatuses, systems, and computer-readable media for taking and sharing pictures of objects of interest at an event or an occasion. A device implementing embodiments of the invention may enable a user to select objects of interest from a view displayed by a display unit coupled to the device. The device may also have pre-programmed objects including objects that the device detects. In addition, the device may detect people using the users' social networks by retrieving images from social networks like Facebook® and LinkedIn®. | 08-01-2013 |
20130201344 | SMART CAMERA FOR TAKING PICTURES AUTOMATICALLY - Methods, apparatuses, systems, and computer-readable media for taking great pictures at an event or an occasion. The techniques described in embodiments of the invention are particularly useful for tracking an object, such as a person dancing or a soccer ball in a soccer game and automatically taking pictures of the object during the event. The user may switch the device to an Event Mode that allows the user to delegate some of the picture-taking responsibilities to the device during an event. In the Event Mode, the device identifies objects of interest for the event. Also, the user may select the objects of interest from the view displayed by the display unit. The device may also have pre-programmed objects including objects that the device detects. In addition, the device may also detect people from the users' social networks by retrieving images from social networks like Facebook® and LinkedIn®. | 08-08-2013 |
20130232011 | RELEVANT CONTENT DELIVERY - Various arrangements for delivery of relevant content to a mobile device of a user are presented.
