Abstract: Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switched communications. The de-jitter buffer methods and apparatus presented modify the playback of packets dependent upon whether silence periods are detected inter-sentence or intra-sentence to optimize voice quality in a communication system. In one example, a de-jitter buffer determines the length of at least one silence period associated with a plurality of received packets and determines a time to transmit a portion of the packets based on the determined length of the silence period. In another example, a silence characterizer unit performs this function.

Abstract: A database for object recognition is generated by performing at least one of intra-object pruning and inter-object pruning, as well as keypoint clustering and selection. Intra-object pruning removes similar and redundant keypoints within an object and different views of the same object, and may be used to generate and associate a significance value, such as a weight, with respect to remaining keypoint descriptors. Inter-object pruning retains the most informative set of descriptors across different objects, by characterizing the discriminability of the keypoint descriptors for all of the objects and removing keypoint descriptors with a discriminability that is less than a threshold. Additionally, a mobile platform may download a geographically relevant portion of the database and perform object recognition by extracting features from the query image and using determined confidence levels for each query feature during outlier removal.

Abstract: Systems and methods for adapting a de-jitter buffer to conform to air link conditions. An air link characteristic may be detected before that characteristic begins to affect packet delivery, such as by slowing or speeding delivery delay at a subscriber station. A receiver-side de-jitter buffer, which adds delay to received packets, may adaptively adjust its size based upon the detected air link characteristic, such that the de-jitter buffer is appropriately sized for anticipated data packets before they are received at the subscriber station.

Abstract: Adaptive De-Jitter Buffer for Voice over IP (VoIP) for packet switch communications. The de-jitter buffer methods and apparatus presented avoid playback of underflows while balancing end-to-end delay. In one example, the de-jitter buffer is recalculated at the beginning of each talkspurt. In another example, talkspurt packets are compressed upon receipt of all remaining packets.

Abstract: In a particular embodiment, a method is disclosed that includes receiving a feedback message at a transmitter, the feedback message including an indication of a magnitude of congestion and a sustainable rate of data transmission at a receiver. The method also includes determining a decongestion rate and a decongestion time based on at least one of the sustainable rate of data transmission and the magnitude of congestion when the magnitude of congestion satisfies a threshold value. The method further includes sending data at the decongestion rate from the transmitter to the receiver for the decongestion time. The method also includes adjusting a data transmission rate at the transmitter to the sustainable rate of data transmission after the decongestion time is ended.

Abstract: 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 Linkedln®.

Abstract: 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.

Abstract: A database for object recognition is modified based on feedback information received from a mobile platform. The feedback information includes information with respect to an image of an object captured by the mobile platform. The feedback information, for example, may include the image, features extracted from the image, a confidence level for the features, posterior probabilities of the features belonging to an object in the database, GPS information, and heading orientation information. The feedback information may be used to improve the database pruning, add content to the database or update the database compression efficiency. The information feedback to the server by the mobile platform may be determined based on a search of a portion of the database performed by the mobile platform using features extracted from a captured query image.
