[QUOTE="ziphnor, post: 71804, member: 14215"] Its not perfect, but i rely on a black gap between the subtitles and the actual image. If no such gap exists i do not move the subtitles. This combined with a sanity check on subtitle areas seem to prevent most problems. The thing i fear most is one subtitle line in the black bar with a gap above it and one line completely in the image. In that case you might end up with two subtitle lines overlaying each other and its virtually impossible to tell the difference reliably. It sounds better than it is, my code is a mess ;) Im trying to to keep seperate tabs on subtitle lines and image lines. My current technique for subtitle lines is not very good. I was surprised that the U and V variance wasnt significantly lower in the subtitle lines. Otherwise i was hoping that the distinct component count for Y would be low(very few different shades). Right now it is 100% reliable for catching subtitle lines, but sometimes also catch image content as subtitles, meaning you have to do alot of sanity checks. Its a work in progress :) The image detection is much more robust using variance and a few other parameters. Basicly my plan is to track subtitle boxes and image boxes seperatly and react VERY slowly to reductions in subtitle size, while being somewhat faster to react when the actual image changes.
