Evaluating Perceptual Distances by Fitting Binomial Distributions to Two-Alternative Forced Choice Data

arXiv:2403.10390v1 Announce Type: new
Abstract: The two-alternative forced choice (2AFC) experimental setup is popular in the visual perception literature, where practitioners aim to understand how human observers perceive distances within triplets that consist of a reference image and two distorted versions of that image. In the past, this had been conducted in controlled environments, with a tournament-style algorithm dictating which images are shown to each participant to rank the distorted images. Recently, crowd-sourced perceptual datasets have emerged, with no images …
