Visually lossless image compression under varying display brightness and viewing distance


Change log

Description

A dataset for visually lossless image compression is intended for evaluation of image artifact visibility metrics. The dataset contains visually lossless thresholds (VLTs) for images depicting a varied selection of contents and compressed with two codecs (JPEG and WebP), which were viewed on monitors of different peak luminance (10 cd/m^2 and 220 cd/m^2), and at different viewing distance (30 pixels-per-degree (ppd) and 60 ppd).

Refer to the README.md and the paper for more details.
