I am looking for the commonly used algorithms to compress images/ videos for transmission over the internet. could you please name me these algorithms and/or papers. Cheers

CheersFor video H.264, which is a subset of MPEG-4, is the most standard but there are no "free" versions of it. Xvid is probably the best combination of being sort-of standard, good performance, and "free". For still images you problem is much simpler, just use JPEG. Steve

You're unlikely to be able to out-research the Xvid developers all on your own. Steve
