ABSTRACT
A good legible label is usually worth, for information, a ton of significant attitude and expression in a historical picture. Multimedia databases are likely to include pictures, and pictures indexed by descriptive words can only be retrieved if the indexer has anticipated the possible indexing words that could be used by any user. Indexers and users have to get to grips with a serious problem—meaning. Indexing is an attempt to describe an object unambiguously in the face of the variation of opinions in regard to meanings and descriptions. To reduce ambiguity a thesaurus is sometimes introduced. In a multimedia system, a simple alphabetically ordered word index may suffice. The major method used for image indexing is for an indexer to label (index) the image with terms (words) considered by him or her to be appropriate.
