  • Patent number: 10930303
    Abstract: Disclosed herein are systems, methods, and non-transitory computer-readable storage media for processing audio. A system configured to practice the method monitors, via a processor of a computing device, an image feed of a user interacting with the computing device and identifies an audio start event in the image feed based on face detection of the user looking at the computing device or a specific region of the computing device. The image feed can be a video stream. The audio start event can be based on a head size, orientation or distance from the computing device, eye position or direction, device orientation, mouth movement, and/or other user features. Then the system initiates processing of a received audio signal based on the audio start event. The system can also identify an audio end event in the image feed and end processing of the received audio signal based on the end event.

    Abstract: A method for determining alignment of cameras at a vehicle includes mounting first and second cameras at a vehicle and providing an image processor at the vehicle. While the vehicle is moving along the road, first image data captured via the first camera is processed to determine movement of a road feature and second image data captured by the second camera is processed to determine movement of the road feature when the road feature is present in the second image data. The determined movement of the road feature in first image data is compared to the determined movement of the road feature in second image data, and an offset of the second camera relative to the first camera is determined, with the offset caused by a rotational or translational change in position of the first or second camera relative to the other.

  • Patent number: 10856009
    Abstract: A method of video coding using coding modes including IntraBC mode (Intra-block copy mode) for a picture is disclosed. The system determines whether the current reference block is located above a current coding unit (CU) containing the current prediction unit (PU) in a vertical direction and whether the current reference block is located on a left side of the current CU in a horizontal direction based on the original block vector (BV). If both results are not true, the original BV is clipped to a clipped BV so that a relocated reference block corresponding to the clipped BV is above the current CU in the vertical direction or to the left side of the current CU in the horizontal direction. The clipped BV is used as a predictor for encoding or decoding of a current BV or used for IntraBC encoding or decoding of the current PU.
