A quick post to mention a nice little paper presented this morning in the "Perceptual rendering methods" session. In "Apparent Display Resolution Enhancement for Moving Images", authors present a method to display a high-resolution image on a lower resolution display but still maintaining the high-quality of the image. In short, the idea is to slightly jitter the image over time to give the impression of a higher resolution image. TV manufacturers just found yet another reason to make you buy a brand new 240Hz HD TV: the possibility to show your 15 Megapixels photographs in a much nicer way.
Another interesting paper in the same session, "Subtle gaze direction" shows how to attract the attention of viewers on a certain part of an image using imperceptible color modulations. The work is supported by a simple psychophysics experiment.
