Abstract: Video coders may perform perspective transformation of reference frames during coding in a manner that conserves processing resources. When a new input frame is available for coding, a camera position for the input frame may be estimated. A video coder may search for reference pictures having similar camera positions as the position of the input frame and, for each reference picture identified, the video coder may perform a prediction search to identify a reference picture that is the best prediction match for the input frame. Once the video coder identifies a reference picture to serve as a prediction source for the input frame, the video coder may derive a transform to match the reference frame data to the input frame data and may transform the reference picture accordingly. The video coder may code the input frame using the transformed reference picture as a prediction reference and may transmit coded frame data and the camera position of the input frame to a decoder. Thus, the video coder may perform derivation and execution of transforms on a limited basis which conserves system resources.

Abstract: Embodiments of the present invention generate estimates of device motion from two data sources on a computing device—a motion sensor and a camera. The device may compare the estimates to each other to determine if they agree. If they agree, the device may confirm that device motion estimates based on the motion sensor are accurate and may output those estimates to an application within the device. If the device motion estimates disagree, the device may alter the motion estimates obtained from the motion sensor before outputting them to the application.
