20090285499 | IN-PICTURE PREDICTION FOR VIDEO CODING - A method of coding video content. The method can include, identifying a first plurality of image blocks within a picture based on at least a first image characteristic that is common to each of the first plurality of image blocks. A first image block group can be dynamically defined. At least one of the image blocks can be selected as a predictor block to predict other image blocks within the first image block group. In another arrangement, at least a first image block and a second image block can be identified within a picture. The second image block can be predicted from the first image block. A displacement vector can be defined to associate the second image block with the first image block. A value representing the displacement vector can be included within a header of the second image block. | 11-19-2009 |
20090320123 | METHOD AND APPARATUS FOR USER RECOGNITION EMPLOYING MOTION PASSWORDS - A method and apparatus are disclosed that authenticate a user of a mobile device with motion sensors. During a learning session, the user initializes the mobile device by providing a motion sample. The mobile device extracts motion features that are unique to the user and converts them to parity bits and to a password shadow. During a recognition session, a motion pattern is gathered from the user moving the mobile device as if it were a virtual pen. The mobile device then uses the stored parity bits to correct small differences between motion patterns exhibited by the same user at different times. The mobile device converts the corrected motion pattern into a motion password that is compared with the stored password shadow. A user is authenticated only if the two values coincide. The system erases the generated motion password. | 12-24-2009 |
20090323575 | METHOD AND APPARATUS FOR MULTICASTING WITHIN A WIRELESS COMMUNICATION NETWORK - A number of uplink transmissions from multiple remote devices is received. The remote devices correspond to a single network node, and each of the uplink transmissions corresponds to a request for content. A subset of remote devices whose uplink transmissions correspond to requests for common content is identified and a Quality of Service (QoS) level corresponding to the number of remote devices in the identified subset is determined. The common content is transmitted to the single network node at the determined QoS level. | 12-31-2009 |
20100086048 | System and Method for Video Image Processing - A system for processing video imaging information, corresponding electronic device, and method of processing video imaging information, are disclosed. In at least one embodiment, the electronic device includes a coder capable of compressing the imaging information for transmission via a communications channel, the video imaging information pertaining to a plurality of video source frames including a current source frame.

20120183173 | System and Method for Content Protection in a Content Delivery Network - An embodiment of an apparatus to authenticate a sequence of video frames includes a process to choose intra-frames of the sequence and sample DC components thereof to produce a set of test fingerprints. To reduce a dimensionality of the test fingerprints, the DC components of the chosen intra-frames are multiplied by a projection matrix formed of eigenvectors associated with the larger eigenvalues of a covariance matrix for a library of frames. The projected test fingerprints are compared against a reference set of fingerprints for authentication. Time-stamp spacings of the chosen intra-frames are determined, and these spacings are employed to select candidate frames for authentication in the reference set of fingerprints. | 07-19-2012 |

20130089107 | Method and Apparatus for Multimedia Queue Management - Methods and systems for a multimedia queue management solution that maintaining graceful Quality of Experience (QoE) degradation are provided. The method selects a frame from all weighted queues based on a gradient function indicating a network performance rate change and a distortion rate caused by the frame and its related frames in the queue, and dropping the selected frame and all its related frames, and continues to drop similarly chosen frame until a network performance rate change caused by the dropping frame and its related frames meets a predetermined performance metric. A frame gradient is a distortion rate divided by a network performance rate change caused by the frame and its related frames, and a distortion rate is based on a sum of each individual frame distortion rate when the frame and its related frames are replaced by some other frames derived from remaining frames based on a replacement method. | 04-11-2013 |
20130121598 | System and Method for Randomized Point Set Geometry Verification for Image Identification - Object recognition can be improved by verifying a geometric consistency between matching interesting points pairs of two images, as objects with the images are more likely to match when the matching interesting points pairs are geometrically consistent. The geometric consistency between matching interesting points pairs can be verified in accordance with a topology code distance vector (D). The topology code distance vector (D) may be evaluated in accordance with a decision tree classifier, which may be trained in accordance with previous or historic topology code distance vectors. The topology code distance vector (D) may be computed from a subset of matching interesting points pairs having the shortest matching distance. | 05-16-2013 |
20130142439 | Scalable Query for Visual Search - A system and a method for progressive queries, which are a sequence of queries for visual search of an image, sent from a sender to a receiver of a communication network, are disclosed. Queries based on a set of feature points and their associated locations of an image may be selected in sequence. A sender sends a first query to a receiver, wherein the first query comprises a number of feature points which is a subset of the set of feature points of the image invariant to rotation and scaling in creating the image. The sender receives a feedback from the receiver, wherein the feedback is generated by the receiver based on searching an image repository using information from the first query. The sender then decides whether there is a match of the image in the image repository based on the received feedback. | 06-06-2013 |
