Welcome to the proceedings of the 17th Multimedia Modeling Conference (MMM 2011) held in Taipei, Taiwan, during January 5–7, 2011. Following the success of the 16 preceding conferences, the 17th MMM brought together researchers, developers, practitioners, and educators in the field of multimedia.

Both practical systems and theories were presented in this conference, thanks to the support of Microsoft Research Asia, Industrial Technology Research Institute, Institute for Information Industry, National Museum of Natural Science, and the Image Processing and Pattern Recognition Society of Taiwan.
