Summary
The supplemental video demonstrates the effect of continuously increasing JPEG compression from Q = 100 to Q=1 and then decreasing JPEG compression back up to Q=100 for an abdominal CT scan. The continuous range of Q values shown in the video is similar to what subjects viewed in Psychometric Experiment 1 (see Results), but in the actual experiment, the viewer was able to actively control the process of scrolling through the stack of images.
