Abstract
Reference frame detection using sensor metadata, including: storing a plurality of first frames each corresponding to first metadata, wherein the first metadata for each first frame of the plurality of first frames is based on first sensor data from one or more sensors; generating a second frame corresponding to second metadata based on the one or more sensors; identifying, based on the first metadata of the plurality of first frames and the second metadata, a reference frame of the plurality of first frames; and encoding the second frame based on the reference frame.
Claims21
A method of reference frame detection using sensor metadata, the method comprising:
- storing a plurality of first frames each corresponding to first metadata, wherein the first metadata for each first frame of the plurality of first frames is based on first sensor data from a plurality of sensors;
- generating a second frame having second metadata that is based on second sensor data from the plurality of sensors;
- identifying, based on the first metadata and the second metadata, a reference frame of the plurality of first frames, wherein the reference frame is identified based on a similarity of an absolute value of metadata of the reference frame to an absolute value of the second metadata exceeding a threshold similarity, and wherein the metadata of the reference frame indicates an opposing direction to the second metadata;
- and
- based on the identification, encoding the second frame based on the reference frame.
An apparatus for reference frame detection using sensor metadata, the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed therein computer program instructions that, when executed by the computer processor, cause the apparatus to:
- store a plurality of first frames each corresponding to first metadata, wherein the first metadata for each first frame of the plurality of first frames is based on first sensor data from a plurality of sensors;
- generate a second frame having second metadata that is based on second sensor data from the plurality of sensors;
- identify, based on the first metadata and the second metadata, a reference frame of the plurality of first frames, wherein the reference frame is identified based on a similarity of an absolute value of metadata of the reference frame to an absolute value of the second metadata exceeding a threshold similarity, and wherein the metadata of the reference frame indicates an opposing direction to the second metadata;
- and
- based on the identification, encode the second frame based on the reference frame.
A computer program product disposed upon a non-transitory computer readable medium, the computer program product comprising computer program instructions for reference frame detection using sensor metadata that, when executed, cause a computer system to:
- store a plurality of first frames each corresponding to first metadata, wherein the first metadata for each first frame of the plurality of first frames is based on first sensor data from a plurality of sensors;
- generate a second frame having second metadata that is based on second sensor data from the plurality of sensors;
- identify, based on the first metadata and the second metadata, a reference frame of the plurality of first frames, wherein the reference frame is identified based on a similarity of an absolute value of metadata of the reference frame to an absolute value of the second metadata exceeding a threshold similarity, and wherein the metadata of the reference frame indicates an opposing direction to the second metadata;
- and
- based on the identification, encode the second frame based on the reference frame.
