The Multimedia Signal Processing Technical Committee (MMSP-TC) of the IEEE Signal Processing Society, which is the organizer of the MMSP workshop, invites proposals for the 2018 workshop edition. The primary aim of the MMSP workshop is to promote the advancement of multimedia signal processing research and technology with special emphasis on the interaction, coordination, synchronization, and joint processing of multimodal signals. Proposals are open to all regions, but to keep with the practice of regional rotation, preference will be given to proposals from Asia/Pacific.
