  • Publication number: 20190246141
    Abstract: Image processing techniques may accelerate coding of viewport data contained within multi-view image data. According to such techniques, an encoder may shifting content of a multi-directional image data according to the viewport location data provided by a decoder. The encoder may code the shifted multi-directional image data by predictive coding, and transmit to the decoder, the coded multi-directional image data and data identifying an amount of the shift. Doing so may move the viewport location to positions in the image data that are coded earlier than the positions that the viewport location naturally occupies and, thereby, may accelerate coding. On decode, a decoder may compare its present viewport location with viewport location data provided by the encoder with coded video data. The decoder may decode the coded video data and extract a portion of the decoded video data corresponding to a present viewport location for display.
