Patent Images

1. A system configured to encode images using adaptive projection selection, the system comprising:

  • a network interface;

    one or more physical processors; and

    a storage apparatus in data communication with the one or more physical processors, the storage apparatus comprising a plurality of machine-readable instructions, the plurality of machine-readable instructions configured to, when executed by the one or more physical processors, cause the system to;

    obtain a content block of data in a first projection;

    obtain a first rate distortion parameter associated with encoding the content block of data in the first projection;

    obtain a second rate distortion parameter associated with encoding the content block of data in a second projection, the second projection differing from the first projection;

    responsive to a determination that the second rate distortion parameter is lower than the first rate distortion parameter, select the second projection for the content block of data;

    obtain an encoded content block by encoding the content block of data in the second projection; and

    provide the encoded content block and a second projection configuration parameter to a target destination via the network interface.
