  • In-loop adaptive wiener filter for video coding and decoding
    Patent number: 10171808
    Abstract: A video encoder may use an adaptive Wiener filter inside the core video encoding loop to improve coding efficiency. In one embodiment, the Wiener filter may be on the input to a motion estimation unit and, in another embodiment, it may be on the output of a motion compensation unit. The taps for the Wiener filter may be determined based on characteristics of at least a region of pixel intensities within a picture. Thus, the filtering may be adaptive in that it varies based on the type of video being processed.

  • Trajectory planning for video stabilization
    Patent number: 10158802
    Abstract: Trajectory planning is described for video stabilization. In one example, a sequence of video frames is received and low-pass filtered. If a subset of the low-pass filtered frames are determined to be zero-motion frames, then a smooth trajectory is estimated for the for the zero-motion frames. Jitter is removed from the zero-motion frames using the smooth trajectory and frame warping is applied to the zero-motion frames with jitter removed.

  • Histogram segmentation based local adaptive filter for video encoding and decoding
    Patent number: 10123011
    Abstract: Reconstructed picture quality for a video codec system may be improved by categorizing reconstructed pixels into different histogram bins with histogram segmentation and then applying different filters on different bins. Histogram segmentation may be performed by averagely dividing the histogram into M bins or adaptively dividing the histogram into N bins based on the histogram characteristics. Here M and N may be a predefined, fixed, non-negative integer value or an adaptively generated value at encoder side and may be sent to decoder through the coded bitstream.

  • SYSTEMS, METHODS, AND COMPUTER PROGRAM PRODUCTS FOR SCALABLE VIDEO CODING BASED ON COEFFICIENT SAMPLING
    Publication number: 20180316937
    Abstract: Methods, systems, and computer program products for the generation of multiple layers of scaled encoded video data compatible with the HEVC standard. Residue from prediction processing may be transformed into coefficients in the frequency domain. The coefficients may then be sampled to create a layer of encoded data. The coefficients may be sampled in different ways to create multiple respective layers. The layers may then be multiplexed and sent to a decoder. There, one or more of the layers may be chosen. The choice of certain layer(s) may be dependent on the desired attributes of the resulting video. A certain level of video quality, frame rate, resolution, and/or bit depth may be desired, for example. The coefficients in the chosen layers may then be assembled to create a version of the residue to be used in video decoding.

  • TECHNOLOGY TO ENCODE 360 DEGREE VIDEO CONTENT
    Publication number: 20180295282
    Abstract: Systems, apparatuses and methods may determine, on a per camera basis, an interest level with respect to panoramic video content, identify a subset of cameras in a plurality of cameras for which the interest level is below a threshold, and reduce power consumption in the subset of cameras. Additionally, technology may determine a projection format associated with panoramic video content, identify one or more discontinuous boundaries in the projection format, and modify an encoding scheme associated with the panoramic video content based on the discontinuous boundaries. Moreover, an encoded frame may be assigned to a temporal scalability layer that has a higher priority than a layer to which an asynchronous space warp frame is assigned. Additionally, technology may reduce the encoding complexity of a boundary between an active region and an inactive region in fisheye content.

    Abstract: A system, method, and computer readable medium may include technology to enable optimal usage of automotive virtual mirrors. A gaze detector monitors a driver's eyes to determine if the driver is looking in the direction of a virtual mirror. If the driver is not looking in the direction of virtual mirror, all virtual mirrors are placed in a low operational mode. If the driver is looking in the direction of a virtual mirror, the virtual mirror being viewed is placed in a high operational mode and all other virtual mirrors are placed in the low operational mode.
