WebMay 1, 2014 · I've been lucky enough to own a 55" model of the lovely ST60 for the last 6-7 months but I've really started to notice the instances of dynamic false contouring on all sorts of material (blu Ray, Netflix, PS4). It shows mostly on skin but also other gradual colour change material - the end... WebSep 8, 2016 · First, we identify the cause of false contours by explaining the human perceptual experiences on them with specific experiments. Next, we propose a precise pixel-based false contour detection...
WebApr 14, 2012 · The general rule of thumb I've experienced is that false contours get more pronounced as the quality of the source is lowered. For example if you watched the same Movie on Blu-Ray, with a prestine transfer at a nice high Bitrate theres a good chance the false contours would be negligable or gone altogether.
