Welcome to the International Workshop on Multimedia Content Analysis and Mining, MCAM 2007. To bene?t from this potential, developers need - liable techniques for the analysis, search, and management of multimedia data, as well as distributed system architectures in which these techniques can be embedded to e?ectively help the users.
