Image data is compressed via a codec, which removes information that is either redundant or largely imperceptible to reduce the bit-rate required to transmit the image to the target device. In so-called `lossy' compression, data from the original image signal cannot be completely recovered upon decoding, which can produce perceptible artifacts or noise. Psychophysical methods exist to assess artefact perceptibility and subjective preference following compression. A current industry standard (ISO/IEC-29170-2 Annex B) specifies a two-alternative forced choice procedure to measure artefact visibility. In this protocol, two versions of the same image are presented side-by-side on a display. In one location an original (reference) and compressed image are temporally interleaved, while in the other location the original is presented repeatedly. Detectable differences between the original and compressed images will appear as localized flicker and observers are asked to indicate which of the images appears to flicker. The recommended statistical procedures outlined in the standards document are descriptive and do not assess the relative performance between codecs.
