Abstract:
1. A method in a processor or video encoder of reducing distortion of video comprising the steps: determining an original value based on a difference between pixel values in corresponding locations in a first picture and a second picture; determining a reconstructed value based on a difference between pixel values in corresponding locations in a reconstruction from an encoding of the first picture and a reconstruction from an encoding of the second picture; determining a comparison value based on a difference between the reconstructed value and the original value, wherein the determining of the comparison value comprises performing max(0,|{circumflex over (f)} determining, based on the comparison value, whether to include the comparison value in a measurement of flicker between the first picture and the second picture to diminish the contribution of comparison values that correspond to small amounts of perceptible flicker, wherein the comparison value is included in the measurement when the comparison value is greater than a just-noticeable-difference threshold.
