Content-based indexing and retrieval of visual information

The ease of capturing and encoding digital images has produced a massive amount of visual information online. As a consequence, grand challenges have emerged in the areas of storage, indexing, and retrieval of visual information in large archives. How does one find a photograph from a large archive that contains millions of pictures? How does a CNN video journalist find a specific clip from the myriad of video tapes, ranging from historical to contemporary, from sports to humanities? Efficient, real-time algorithms and systems are needed to address these needs of not only professionals but for users who want to find visual information online.
