Dear Authors,

It is my pleasure to announce the overall winner of the 2009 ACM Multimedia Open Source Software Competition. This year, the honor falls on “Caliph & Emir: MPEG-7 photo annotation and retrieval”, an open-source project led by Mathias Lux at Klagenfurt University, Austria (

Congratulations to Mathias and his co-contributors for producing a high-quality open-source implementation of a large part of the MPEG-7 standard, with significant potential impact.

I would also like to thank all of you for participating in this year’s open-source software competition, and for contributing to the research and open-source communities. We had 17 high-quality submissions this year (originating from 12 countries), of which 5 projects were selected by the review committee for presentation, demonstration and publication.

Thank you again for making this a high-quality competition.

Apostol (Paul) Natsev, Open Source Competition Chair
