Abstract
An example device for calculating a quality metric for video data includes a memory configured to store a spherical image of the video data, and one or more processors implemented using discrete logic circuitry and configured to determine a user field of view for the spherical image, determine weighting values for pixels of the spherical image based on the user field of view; and calculate a quality metric for the user field of view of the spherical image using the weighting values, wherein calculating the quality metric comprises applying the weighting values to values for the pixels.
Claims30
A method of calculating a quality metric for video data, the method comprising:
- determining a user field of view for a spherical image of the video data;
- determining weighting values for pixels of the spherical image based on the user field of view;
- and
- calculating a quality metric for the user field of view of the spherical image using the weighting values, wherein calculating the quality metric comprises applying the weighting values to values for the pixels.
