A secure dispute settlement system is described. The secure dispute settlement system may receive first injury data associated with first injuries of an injured party. The secure dispute settlement system may identify, based on the first injury data, historical settlement data associated with a historical settlement. The historical settlement data may indicate second injury data associated with second injuries that are similar to the first injuries, and a value that the second injuries were settled for. The secure dispute settlement system may generate, based on the historical settlement, a settlement report that indicates an estimated fair value for the first injuries.

Systems and methods for facilitating shared access-right evaluation using linked communication channels are provided. A first communication can be received over a first communication link from a first user device, and a second communication can be received over a second communication link from a second user device. The first and second communications can include requests for the assignment of access rights. Map data can be generated and transmitted to each of the first and second user devices. Each user device can display a visual representation of access-right data. Further, a communication session can be facilitated between the first user device and the second user device. The communication session can be presented on the visual representation for each user device so that the first user and the second user can collaboratively evaluate access rights.

A method and apparatus for creating and updating a facial image database from a collection of digital images is disclosed. A set of detected faces from a digital image collection is stored in a facial image database, along with data pertaining to them. At least one facial recognition template for each face in the first set is computed, and the images in the set are grouped according to the facial recognition template into similarity groups. Another embodiment is a naming tool for assigning names to a plurality of faces detected in a digital image collection. A facial image database stores data pertaining to facial images detected in images of a digital image collection. In addition, the naming tool may include a graphical user interface, a face detection module that detects faces in images of the digital image collection and stores data pertaining to the detected faces in the facial image database, a face recognition module that computes at least one facial recognition template for each facial image in the facial image database, and a similarity grouping module that groups facial images in the facial image database according to the respective templates such that similar facial images belong to one similarity group.

Disclosed are a system, method, apparatus, and computer readable media containing instructions for pre-filtering one or more pictures of a prediction structure. In an exemplary embodiment, a system includes an input for receiving the one or more pictures and a pre-filter, operatively coupled to the input and receiving the one or more pictures. The pre-filter can include a prediction position determining module for determining a position of at least one picture in the prediction structure, a context memory for storing determined position information, and a filter module for selecting a filter context based on the determined position and using the selected filter context to filter the at least one picture.

Disclosed herein are techniques and computer readable media containing instructions arranged to utilize existing video compression techniques to enhance a visually appealing high frame rate, without incurring the bitrate and computational complexity common to high frame rate coding using conventional techniques. SVC skip slices—slices in which the slice_skip_flag in the slice header is set to a value of 1—require very few bits in the bitstream, thereby keeping the bitrate overhead very low. Also, when using an appropriate implementation, the computational requirements for coding an enhancement layer picture consisting entirely of skipped slices are almost negligible. In addition, skipped slices in an enhancement layer inherit motion information from the base layer(s), thereby minimizing, if not eliminating, the possibly bad correlation between nonlinear motion and linear interpolation. Further, the issue of radical brightness changes of a picture (or significant part thereof) does not exist, as the base layer is coded at full frame rate and can contain information related to the brightness change that can also be inherited by the enhancement layer.

The present invention provides, in one embodiment, a system and method for concealing video errors. The system includes a coding engine for processing each frame of a video signal to generate macroblocks, selecting a refresh interval based upon network communication parameters, and encoding one or more of the macroblocks as refresh intra-coded macroblocks based upon the selected refresh interval. The refresh intra-coded macroblocks are placed into discrete data packets for transmission across a network to one or more remote devices. Upon receiving other refresh intra-coded macroblocks from a remote device via the network, the coding engine decodes the received intra-coded macroblocks, and places the decoded macroblocks in a newly decoded video frame to be used as reference frame macroblocks for reducing video errors associated with prediction drift.

Systems and methods for picture segmentation through columns and slices in video encoding and decoding. A video picture is divided into a plurality of columns, each column covering only a part of the video picture in a horizontal dimension. All coded tree blocks (“CTBs”) belonging to a slice may belong to one or more columns. The columns may be used to break the same or different prediction or in-loop filtering mechanisms of the video coding, and the CTB scan order used for encoding and/or decoding may be local to a column. Column widths may be indicated in a parameter set and/or may be adjusted at the slice level. At the decoder, column width may be parsed from the bitstream, and slice decoding may occur in one or more columns.

Systems and methods for using redundant pictures and slice groups to encode spatially scalable H.264 Baseline profile conformant video and to route that video to endpoints of varying capabilities without using the Scalable Video extension of H.264 or transcoding. Reduced resolution versions of primary coded pictures are encoded as slice groups in a full-resolution composite pictures, which are added to the video bitstream as redundant pictures. A router then processes the spatially scaled video bitstream into separate streams having different resolutions and routes these to endpoints of varying capabilities.
