Abstract
A method receives a video. The method analyzes information for a pixel of a frame in the video to determine a first value and a second value for the pixel. The first value is based on an image structure formed by the pixel in the frame and the second value is based on interframe motion of the image structure at the pixel. A third value is determined for an amount of judder based on the first value and the second value. The method outputs the third value to evaluate the video.
Claims20
A method comprising:
- receiving, by a computing device, a video;
- analyzing, by the computing device, information for a pixel of a frame in the video to determine a first value and a second value for the pixel, wherein:
- the first value is based on an image structure formed by the pixel in the frame and the second value is based on interframe motion of the image structure at the pixel,
- the first value comprises a first change of a characteristic in a direction of the interframe motion of the image structure at the pixel, and
- the second value comprises a second change in the interframe motion of the image structure at the pixel;
- determining, by the computing device, a third value for an amount of judder based on the first value and the second value;
- and
- outputting, by the computing device, the third value to evaluate the video.
A non-transitory computer-readable storage medium having stored thereon computer executable instructions, which when executed by a computing device, cause the computing device to be operable for:
- receiving a video;
- analyzing information for a pixel of a frame in the video to determine a first value and a second value for the pixel, wherein:
- the first value is based on an image structure formed by the pixel in the frame and the second value is based on interframe motion of the image structure at the pixel,
- the first value comprises a first change of a characteristic in a direction of the interframe motion of the image structure at the pixel, and
- the second value comprises a second change in the interframe motion of the image structure at the pixel;
- determining a third value for an amount of judder based on the first value and the second value;
- and
- outputting the third value to evaluate the video.
An apparatus comprising:
- one or more computer processors;
- and
- a computer-readable storage medium comprising instructions for controlling the one or more computer processors to be operable for:
- receiving a video;
- analyzing information for a pixel of a frame in the video to determine a first value and a second value for the pixel, wherein:
- the first value is based on an image structure formed by the pixel in the frame and the second value is based on interframe motion of the image structure at the pixel,
- the first value comprises a first change of a characteristic in a direction of the interframe motion of the image structure at the pixel, and
- the second value comprises a second change in the interframe motion of the image structure at the pixel;
- determining a third value for an amount of judder based on the first value and the second value;
- and
- outputting the third value to evaluate the video.
