  • Patent number: 10775881
    Abstract: A computer system with one or more cameras monitors the head poses produced by a head-tracking system and produces a pass/fail indication that the head poses are reliable in a high assurance environment. The system may identify individual fiducials and independently verifying that they conform to the computed pose; and/or compute a location of fiducials as would be observed by a single verification camera and compare the computed locations to actual observed locations. The verification camera may be part of a second head-tracking system, utilized while not operating in its ordinary capacity. The computer system may also calibrate the head-tracking system to account for temperature and pressure fluctuations and perform image stabilization before the image frames are passed to the head-tracking system for processing by observing separate fiducials in fixed locations relative to the camera.

  • Patent number: 10757376
    Abstract: An unmanned aerial vehicle (UAV) may perform a surveillance action at a property of an authorized party. The property may be defined by a geo-fence, which may be a virtual perimeter or boundary around a real-world geographic area. The UAV may image the property to generate surveillance images, and the surveillance images may include image data of objects inside the geo-fence and image data of objects outside the geo-fence. While gathering surveillance images, or after the surveillance images have been gathered, the geo-fence information may be used to obscure or remove image data referring to objects outside the geo-fence. Geo-clipped surveillance images may be generated by physically constraining a sensor of the UAV, by performing pre-image capture processing, or post-image capture processing. Geo-clipped surveillance images may be limited to authorized property, so privacy is ensured for private persons and property.

  • Patent number: 10757419
    Abstract: Videos may be characterized by objective metrics that quantify video quality. Embodiments are directed to target bitrate prediction methods in which one or more objective metrics may serve as inputs into a model that predicts a mean opinion score (MOS), a measure of perceptual quality, as a function of metric values. The model may be derived by generating training data through conducting subjective tests on a set of video encodings, obtaining MOS data from the subjective tests, and correlating the MOS data with metric measurements on the training data. The MOS predictions may be extended to predict the target (encoding) bitrate that achieves a desired MOS value. The target bitrate prediction methods may be applied to segments of a video. The methods may be made computationally faster by applying temporal subsampling.

  • Patent number: 10743013
    Abstract: Reconstructing a second component signal relating to a second component of a multi-component picture from a spatially corresponding portion of a reconstructed first component signal and a correction signal derived from a data stream for the second component promises increased coding efficiency over a broader range of multi-component picture content. By including the spatially corresponding portion of the reconstructed first component signal into the reconstruction of the second component signal, any remaining inter-component redundancies/correlations present such as still present despite a possibly a priori performed component space transformation, or present because of having been introduced by such a priori performed component space transformation, for example, may readily be removed by way of the inter-component redundancy/correlation reduction of the second component signal.

  • Patent number: 10721476
    Abstract: Rate control techniques are provided for encoding an input video sequence into a compressed coded bitstream with multiple coding passes. The final coding pass may comprise final splices with non-overlapping frames that do not extend into neighboring final splices. A final splice in the final coding pass may correspond to at least one non-final splice in a non-final coding pass. A non-final splice may have overlapping frames that extend into neighboring final splices in the final coding pass. The overlapping frames in the non-final splice may be used to derive complexity information about the neighboring final splices. The complexity information about the neighboring final splices, as derived from the overlapping frames, may be used to allocate or improve rate control related budgets in encoding the final splice into the compressed coded bitstream in the final coding pass.
