摘要： Systems and methods of identifying media content, such as video content, that employ fingerprint matching at the level of video frames. The presently disclosed systems and methods of identifying media content can extract one or more fingerprints from a plurality of video frames included in query video content, and, for each of the plurality of video frames from the query video content, perform frame-level fingerprint matching of the extracted fingerprints against fingerprints extracted from video frames included in a plurality of reference video content. Using the results of such frame-level fingerprint matching, the presently disclosed systems and methods of identifying media content can identify the query content in relation to an overall sequence of video frames from at least one of the plurality of reference content, and/or in relation to respective video frames included in a sequence of video frames from the reference content.

摘要： A system and method of perceptual quality assessment for multimedia content in a communications network employing digital watermarking. A content preparer prepares content for quality assessment by embedding digital watermarks into the multimedia data, each watermark having a different level of robustness with respect to a specified type of potential degradation introduced during content transmission. A quality assessor provides an assessment of the quality of the transmitted content by attempting to detect the presence of at least one watermark, and calculating a quality assessment score based on the level(s) of robustness of the detected watermark(s) with respect to the specified type of potential degradation. The quality assessment score can be calculated based on the level of robustness of the least robust watermark whose presence was successfully detected by the quality assessor. The quality assessor generates an output indication of the transmitted content fidelity using any suitable type of output indication.

摘要： Systems and methods of perceptual quality monitoring of video information, communications, and entertainment that can estimate the perceptual quality of video with high accuracy, and can be used to produce quality scores that better correlate with subjective quality scores of an end user. The systems and methods of perceptual quality monitoring of video can generate, from an encoded input video bitstream, estimates of one or more quality parameters relating to the video, such as the coding bit rate parameter, the video frame rate parameter, and the packet loss rate parameter, and provide these video quality parameter estimates to a predetermined video quality estimation model. Because the estimates of the video quality parameters are generated from the encoded input video bitstream as it is being received, the systems and methods are suitable for use as QoE monitoring tools.

摘要： Systems and methods of tracking multimedia content transmitted over at least one network to one or more mobile devices that may be employed to verify delivery of the multimedia content to the respective mobile devices, and to determine the perceptual quality (also referred to herein as “quality of experience” or “QoE”) of the multimedia content at the respective mobile devices. The systems and methods employ content identification techniques in conjunction with objective quality measures to allow mapping of the quality of experience or QoE to specific multimedia content, which may include audio content, imagery content, textual content, and/or video content.

摘要： A railroad track inspection system and method for facilitating inspection of a rail component while traveling on the railroad track. The railroad track inspection system includes an optical path protection device for a protective window for optical sensors of an optical inspection system when it becomes contaminated with dirt, dust, mud, grease, and other contaminants that block or obscure an optical path of the sensors. The optical path protection device eliminates the need for a human operator to perform the periodic cleaning of the protective window by using a clear film with an automated advancement mechanism for providing clean film, as needed, for keeping the optical path of the optical sensors unobstructed and clear.

摘要： A railroad test vehicle extending in a longitudinal direction comprises a measurement axle comprising two flanged wheels rotatable about a measuring axis extending transversely to the longitudinal direction and adapted to run on two track rails. A cross member extends transversely to the longitudinal direction, is vertically spaced from an underside of the vehicle and is affixed thereto. The connection between the measurement axle and the cross member comprises two trunnions transversely spaced from each other and mounted on the cross member, each trunnion defining a clearance with the cross member sufficient to enable the trunnion to be freely tilted to either side of the vehicle about an axis extending in the longitudinal direction, a support frame mounted on each trunnion for pivoting freely about an axis extending perpendicularly to the longitudinal direction, and two pairs of linkages, the pairs being transversely spaced from each other by the same distance as the transversely spaced trunnions. Each pair comprises an upper swing arm and a lower swing arm spaced from the upper swing arm in a vertical direction. A joint connects each swing arm to the measurement axle, and a hinge connects each swing arm either to a respective one of the support frames. At least one pressure cylinder having a vertically extending cylinder axis exerts a contact force pressing the measurement axle against the rails.

摘要： A highway self-restoring channelizing device that is placed along the traveled way to guide motorists through temporary construction zones. The self-restoring channelizing device comprises a foam rubber body encased in a reinforced rubber outer casing that is attached to a rigid base. The base is in turn adhered or anchored to highway pavement. The self-restoring channelizing device has a shape that when viewed in elevation from the side has a wide base sloping upward to a narrow almost vertical upper portion. When viewed from the direction of traffic the self-restoring channelizing device has a tall rectangular shape. The self-restoring channelizing device will not displace and immediately restores to its original shape when impacted or run-over by a vehicle. The self-restoring channelizing device is quickly adhered to pavement and can be removed using a scraper type tool.
