<strong>IEEE</strong> COMSOC MMTC R-LetterMessage from the Review BoardIntroductionSince the launch <strong>of</strong> R-Letter in October 2010,there have been fifteen publications. Creditsshould be given to all contributors. In order todeliver timely bi-monthly R-Letter, the ReviewBoard needs to maintain a pool <strong>of</strong> nominatedpapers so that board members can have sufficienttime to complete the review and editorial process.Therefore, we would like to invite the MMTCcommunity to actively participate in thenomination process. Please refer PaperNomination Policy at the end <strong>of</strong> this issue.Nominators <strong>of</strong> Review articles will beacknowledged in the respective R-Letter.The Review Board aims at recommending recent(within one and half year) state-<strong>of</strong>-the-art andemerging publications in the literature. Thetopics should be <strong>of</strong> general interest for theMMTC community. In this issue, the twodistinguished articles discuss multi-view videoencoding and telepresence based on an array <strong>of</strong>Kinect sensor.Distinguished CategoryThe growing need for applications and serviceswhich are ranging from stereoscopic telepresencesystem to multi-view encoded content isincreasing rapidly. However, it is not sure howthese services may be deployed with commodityhardware like the Kinect. For multi-view videoencoding, the actual encoding delay is animportant issue which calls for the analysis andoptimization there<strong>of</strong>.The first paper, published in <strong>IEEE</strong> Journal <strong>of</strong>Selected Topics in Signal Processing, provides aframework for the analysis and optimization <strong>of</strong>the encoding latency for multi-view video. Thesecond paper, published in Elsevier: Computers& Graphics, shows how to use commodity depthcameras in order to provide enhanced personalauto-stereoscopic telepresence.Regular CategoryWhile more and more social data are available,how to extract visual signals and images andanalyze them have been extensively studied inthe literature. Meanwhile, how to allocateresources for these services is another importantarea to study. In this issue, the regular categoryhas assembled six papers on these topics. Thefirst paper, published in the <strong>IEEE</strong> Transactionson Signal Processing, Paper proposes theconstruction <strong>of</strong> two-channel wavelet filter banksfor analyzing graph-signals. The second paper,from <strong>IEEE</strong> Transactions on Multimedia,proposes a blind resource allocation scheme bytaking into account the fairness among the users.The authors derive the convergence time <strong>of</strong> theproposed scheme and show that the proposedscheme provides almost the same MoS value asthe optimum solution which knows QoE modelin advance. The third paper, published in <strong>IEEE</strong>Transactions on Multimedia, the authors providea generalized framework for optimizing theresources needed to support real-time IPTVservices in a virtualized architecture, which takesadvantage <strong>of</strong> the different deadlines associatedwith each service to effectively multiplex theseservices by time-shifting scheduling. The fourthpaper is the best paper from <strong>IEEE</strong> ICME’<strong>2013</strong>,which proposes a novel scheme to automaticallysummarize and depict human movements from2D videos without 3D motion capture ormanually labeled data. The fifth paper is thebest student paper award <strong>of</strong> <strong>IEEE</strong> ICME’<strong>2013</strong>.The authors propose a unified model toautomatically identify visual concepts andestimate their visual characteristics, or visualness,from a large-scale image dataset. We would liketo thank all the authors, reviewers, nominators,editors and others who contribute to the release<strong>of</strong> this issue. The sixth paper, published in the<strong>IEEE</strong> Wireless <strong>Communications</strong>, propose across-layer optimization framework forcooperative video summary transmission.We would like to thank all the authors,nominators, reviewers, editors and others whocontribute to the release <strong>of</strong> this issue.http://committees.comsoc.org/mmc 2/22 Vol.4, No.4, <strong>August</strong> <strong>2013</strong>
