Multimedia databases

Pictures are difficult to index. Perhaps that is why until quite recently very little work was done on that subject. Picture indexing was discussed in chapter 10. However, pictures are but one component of a multimedia database. Once multimedia databases become established and grow large, it will be realized that they are almost useless unless well indexed. It is not yet clear what difficulties have been met, how many large multimedia databases exist, or how great is the need for them.
