Abstract
A computer-implemented method of transmitting video data. A sequence of video frames is received. A warp operation for a first frame and a reference frame of the sequence of video frames is determined, wherein the warp operation defines a transformation of the reference frame to give an approximation of the first frame. One or more regions of interest of the first frame are identified. Encoded image data from the image data of the one of more regions of interest of the first frame is generated using an image encoder. The warp operation and the encoded image data are transmitted.
Claims20
A method comprising:
- receiving a sequence of frames;
- determining a warp operation for a particular frame and a reference frame from the sequence of frames, wherein the warp operation defines a transformation of the reference frame to approximate the particular frame;
- generating, using an encoder, encoded image data of one or more regions of interest of the particular frame;
- generating a reconstructed frame using the encoded image data and the warp operation;
- generating a score that reflects a similarity between the reconstructed frame and the particular frame;
- determining that the score satisfies a threshold value;
- and
- in response to determining that the score satisfies the threshold value, transmitting the reconstructed frame.
A system comprising:
- one or more computers and one or more storage devices on which are stored instructions that are operable, when executed by the one or more computers, to cause the one or more computers to perform operations comprising:
- receiving a sequence of video frames;
- determining a warp operation for a particular frame and a reference frame from the sequence of video frames, wherein the warp operation defines a transformation of the reference frame to approximate the particular frame;
- generating, using an encoder, encoded image data of one or more regions of interest of the particular frame;
- generating a reconstructed frame using the encoded image data and the warp operation;
- generating a score that reflects a similarity between the reconstructed frame and the particular frame;
- determining that the score satisfies a threshold value;
- and
- in response to determining that the score satisfies the threshold value, transmitting the reconstructed frame.
One or more non-transitory computer storage media encoded with computer program instructions that when executed by one or more computers cause the one or more computers to perform operations comprising:
- receiving a sequence of video frames;
- determining a warp operation for a particular frame and a reference frame from the sequence of video frames, wherein the warp operation defines a transformation of the reference frame to approximate the particular frame;
- generating, using an encoder, encoded image data of one or more regions of interest of the particular frame;
- generating a reconstructed frame using the encoded image data and the warp operation;
- generating a score that reflects a similarity between the reconstructed frame and the particular frame;
- determining that the score satisfies a threshold value;
- and
- in response to determining that the score satisfies the threshold value, transmitting the reconstructed frame.
