While working on compression , one of the issues is to find good modern test images or test videos.As a result i think it would be a good idea to compile a list.
Info on Internet use vs Camera Images
Color images(Internet use):
Jyrki Alakuijala image corpus
WyohKnott image corpus
Rawzor test images
Silesia compression corpus
Xiph.org Video Test Media [derf's collection]
EBU Test Sequence ( look for "Public Test Sequences" on the site. You have to register to get FTP access.)
Elephant dream lossless video and audio
Kindly suggest some more in the comments.
