1st Image Quality Assessment Workshop Proceedings
August 16, 2022


Thanks to the increasing storage capabilities and internet speed, modern image codecs have made very high-quality images possible and desirable. However, the existing standardized assessment methodologies, e.g. ITU-Rec. BT.500, are more suitable for evaluating the visual appeal of images (how obvious and/or annoying the artifacts are) than for evaluating their visual fidelity (how true the images are to the original). The methodology described in AIC-2, on the other hand, approaches the problem from the other end: it is based on a very sensitive flicker test that will catch even the slightest visual distortion.

In this context, the JPEG Committee has launched a new activity on Assessment of Image Coding, also referred to as JPEG AIC. This activity is a continuation of the previous standardization efforts (AIC-1 and AIC-2) and aims to develop a new standard, known as AIC-3. The scope of AIC activities is to specify standards or best practices w.r.t. subjective and objective image quality assessment methodologies that target a range from high quality to near-visually lossless quality.
