Yahoo has released a massive data set of Flickr images and videos that are free to share under their copyright licenses. Yahoo believes the data set, which comprises 99.3 million images and 0.7 million videos, is one of the largest public multimedia data sets ever released. The data set, which promises to be a boon to computer vision researchers, contains metadata including title, description, camera type, and tags. About 49 million of the images are also geotagged. Yahoo is collaborating with the Lawrence Livermore National Laboratory to provide compute resources through the lab’s supercomputer to help researchers analyze the data.
