Multimedia content analysis and mining

Welcome to the International Workshop on Multimedia Content Analysis and Mining, MCAM 2007. Our workshop gives a snapshot of the current wor- wide research in multimedia analysis. Through recent advances in computing, networking, and data storage, multimedia will create new interesting technical possibilities in a wide range of ? elds, such as entertainment, commerce, science, medicine, and public safety. 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. Recently, there have been many workshops and meetings dedicated to M- timedia, but most of them followed the standard pattern consisting mainly of oral and poster presentations. We all feel that there is a need for a meeting that really is a workshop, i. e., one that provides a lot of opportunities for discussions and dissemination. Consequently, the format of the workshop consists of 4 p- els on hot topics in multimedia followedby discussions and poster presentations. The topics of the panels are: Multimedia Analysis and Applications, Multi- dia Search and Mining, P2P Streaming, and Security. This volume contains a number of invited contributions from experts in the area as well as the selected regular contributions. This year 139 submissions from 13 countries were submitted and 46 were accepted for presentation at the conference after being reviewed by the Program Committee members.
