1A-1: Strategic Research and Innovation in Optical Communications:
An Excited-State Lifetime of Forty Years at AT&T Bell Labs (Keynote)
Tingye Li, Emeritus, AT&T Bell Laboratory, USA

Strategic research may be regarded as that mission-oriented work which is focused on
producing significant advances and innovations in a particular field. It can be fundamental
or applied, but always involves having realistic goals in mind, a deep understanding ofphysical principles and a good appreciation for applications issues. It is often associated witha vision that could launch a new technical direction and spawn innovations that would
engender significant industrial and societal impact. Innovation, on the other hand, is theprocess by which novel ideas or concepts are created and translated into viable applications.
The innovation process can initially be a one-person or small-group effort, but later would
evolve into a large-scale, institutionally-supported, mission-driven team endeavor, motivatedby significant and measurable operational and economical gains. In this talk, I shall relate
my experiences and observations as a participant of strategic research and innovation in thefield of optical fiber communications at AT&T Bell Laboratories over a professional career offour decades.

intelligent transportation, mobile Internet access, and many location dependent commercial
applications. The growing importance of inter-vehicular communications has been recognized
by governments, academia, and industry. VANETs have unique features that provide
opportunities for optimizations, but also have complex aspects that challenge the systemdesign and implementation. This presentation will provide an overview of the state-of-the-art
in the development of VANETs, discuss research challenges, and identify some open issues
for resource allocation, network control, and service provisioning in VANETs.

This report will focus mainly on the recent progress in RISE on the research anddevelopment of sensitive superconducting detectors at terahertz (THz) and optical waveband,
including superconducting hot electron bolometer (HEB) THz mixer and superconducting
nanowire single photon detector (SNSPD) For the HEB THz mixer, the double sideband
receiver noise temperature of 1135 K at 2.5 THz has been obtained at 4.2 K without
corrections. It is about 8.5 times of the quantum limit noise temperature and same with theperformance of the HEB used in the Herschel Satellite. For the SNSPD, the maximum
system detector efficiency of 32% for 404 nm photons, 21% for 660 nm photons and 10% for1310 nm photons have been achieved. Its applications will be discussed.

2A-1: Challenges to Ultrafast and High-Spectral-Density OpticalCommunications Systems
Masataka Nakazawa, Tohoku University, Japan

We present our recent progress toward the realization of ultrahigh-speed coherent opticaltransmission using ultrashort pulse technology and an advanced modulation format. We firstdescribe 2.56 Tbit/s/ch optical time division multiplexing (OTDM) transmission using an
ultrafast optical Fourier transformation technique. We then focus on coherent opticaltransmission using quadrature amplitude modulation (QAM) with a multiplicity of
512~1024, which aims at a spectral efficiency approaching the Shannon limit. Finally, wedemonstrate an ultrafast, spectral-efficient transmission with an OTDM-RZ/QAM scheme, inwhich 800 Gbit/s, 32 RZ/QAM signal was successfully transmitted over 225 km using a novel
RZ-CW conversion technique.

Kunio Sawaya, Tohoku University, Japan

An approach using reflectarray to eliminate blindness in wireless propagation channel and toincrease the multipath richness for MIMO (Multiple Input Multiple Output) communications
is studied. Theoretical and numerical approaches are shown to design the reflectarray which
scatters the incident wave to a desired direction at dual frequency band. The reflectarrayhaving characteristics such as the dual-polarization control and broad bandwidth is alsostudied. An outdoor experiment is demonstrated to show the performance of the reflectarrayin improving propagation channel of wireless communications.

2A-3: Recent Advances in Gigabit Wireless Technology
Fumiyuki Adachi, Tohoku University, Japan

Gigabit wireless technology that can achieve data transmissions of higher-than-1Gbps isdemanded. However, unfortunately, the available wireless bandwidth is limited. Particularattention is paid to frequency-domain multi-input/multi-output (MIMO) multiplexing tosignificantly increase the throughput without expanding the signal bandwidth. Besides thegigabit wireless signal processing, another important issue exists. Gigabit data services needprohibitively high transmit power if the present network architecture is employed. A new
wireless network that can significantly reduce the transmit power is required. An
introduction of distributed antenna network architecture is a promising solution to thisissue. In this talk, we will overview the state-of-the-art gigabit wireless technology.

2A-4: A Robust Optimization of Designing P2P Systems with Attack and Fault
Nei Kato, Tohoku University, Japan

Distributed networks have attracted much attention due to their scalability andinexpensiveness as compared to traditional centralized networks. While distributed
networks are appropriate to construct large-scale networks, insuring the tolerance to both
attacks and faults is still an unresolved issue. In this paper, we classify and evaluate theexisting distributed networks based on their degree distributions. We also propose a method
to construct a network based on bimodal degree distribution, which is tolerant to attacks andnetwork faults.

2B-1: Recent Progress in Spintronics Technology for Nonvolatile VLSIs
Hideo Ohno, Tohoku University, Japan

Nonvolatile VLSIs, which embedded spin-transfer torque magnetic tunnel junctions (MTJs)
with perpendicular magnetic anisotropy electrodes, have attracted much attention due to the
expectation of reduction of power consumption and of interconnection delay. We found outthat the perpendicular magnetic anisotropy in CoFeB/MgO stack structure resulting frominterfacial anisotropy. The perpendicular anisotropy CoFeB/MgO MTJs (p-MTJs) exhibit
high potential to achieve the high tunnel magnetoresistance (TMR) ratio, high thermal
stability Ʀ=E/kBT and low switching current down to the junction size as low as 40 nm indiameter, simultaneously. These p-MTJ technologies will be a promising building block for
spintronics based nonvolatile VLSIs.

2B-2: Tailor-Made Nano-Structured Material for Highly Qualified Spin Related
Devices
Migaku Takahashi, Tohoku University, Japan

Highly qualified spin related devices such as ultra-high density hard disk drive (HDD),
magnetic random access memory (MRAM), motor/generator, and antenna for high frequency
use are inevitable requirements for future IT technology in sustainable and/or low-carbon
society. Tailor-made spin nano-structured materials by precisely controlled fabrication
technology with nano-scale in each devices and understanding their nanomagnetics are
essential from the view point of material, process, and physics. Within the frame work of thepresent paper, correlation between tailor-made nano-structured material and magnetic
properties developed for each categorized research items mentioned above will be widely
discussed in connection with spin related devices.

2B-3: Perspective of 10 Tbit/inch2 Information Storage
Hiroaki Muraoka, Tohoku University, Japan

Worldwide created information quantity is rapidly growing as 10 times per 5 years. The
demand of areal density of HDD is therefore strong. Hard disk drives reached to the areal
density of 1 Tbit/inch2, where the bit area is only 625 nm2. Several challenges are still
remained to go beyond the terabit recording. In order to achieve 10 Tbit/inch2, a narrow bit
length of 8 nm is required. For such tiny bit writing, the first challenge is writing resolution,
or writing head field gradient. Magnetic fluctuations such as switching field distribution or
grain size dispersion must be also satisfied. Next challenge will be at around 3 nm or 100
Tbit/inch2, where we will confront thermal and granular limit.

Yasuo Cho, Tohoku University, Japan

Scanning nonlinear dielectric microscopy (SNDM) is reviewed. First, experimental results on
the detection of ferroelectric domains are shown following a presentation about the theory
and principle of SNDM. Next, a noncontact scanning nonlinear dielectric microscopy(NC-SNDM) is proposed. Using NC-SNDM, we clearly resolve the electric dipole moment
distribution of Si atoms on a Si(111)7x7 surface. We also succeeded to resolve a fullerene (C60)
molecule. Since the technique is applicable not only to semiconductors but also to both polarand non-polar dielectric materials, SrTiO3 and TiO2 surfaces were observed. Finally, wecharacterize an ultrahigh density ferroelectric data storage system using SNDM.

3A-1: Constrained Nonnegative Matrix Factorization for Recognition Tasks
from Facial Images (Invited)
Chiou-Ting Hsu, National Tsing Hua University, Taiwan

Nonnegative matrix factorization (NMF) tends to characterize local feature variation andhas been shown to be more interpretable on facial images. In this paper, we focus on threeproblems of facial image analysis, including facial age estimation, age-invariant facerecognition, and expression recognition. To solve the above recognition tasks, we propose to
extract task-specific features by using a supervised NMF (SNMF). In addition, sincedifferent persons usually have very different appearance changes with respect to age or
expression, it is not easy to find a set of good features feasible for all individuals. To overcome
this difficulty, we further include a person-independent constraint and propose a new
approach called person-independent SNMF (PI-SNMF) to characterize local face
appearance. We conduct PI-SNMF on two kinds of face databases for the recognition tasks.
Our experiments show that the derived facial bases indeed characterize the task-specificlocal variations and are successfully extended to tackle age-invariant face recognition, whichis still an open problem among existing facial image analysis.

3A-2: New VLSI Platform for Real-World Intelligent Integrated Systems Basedon Algorithm Selection
Michitaka Kameyama, Tohoku University, Japan

A real-world intelligent system consists of three basic modules: environment recognition,
prediction or estimation, and behavior planning. We propose a VLSI platform that isuniversal for every application and that includes an intelligent algorithm framework. The
main reason for the VLSI platform is the requirement for high-speed processing to provide
the best results as well as low-cost implementation. However, real-world information ishighly complex and cannot be reliably analyzed using a single algorithm. Thus, amechanism, that for any of the three computational stages select the best possible algorithm
is developed. This selection mechanism is based on machine learning and uses features
extracted from the real-world information. The resulting selection mechanism guarantees
the most suitable algorithm usage in the recognition and behavior planning while selecting
the best context for the estimation stage. To develop a low-cost, high-performance andlow-power VLSI platform, we present a novel dynamic reconfigurable VLSI processor for
real-time adaptation of the algorithm selection. The new architectures include alogic-in-memory architecture to solve data transfer bottleneck, an intra-chip packet routing
scheme to reduce the size of the configuration memory, and power gating with asynchronous
control to achieve low power.

3A-3: Wire-Fault-Tolerant Delay-Insensitive Asynchronous Communication
Link with Current-Level Monitoring
Takahiro Hanyu, Tohoku University, Japan

A wire-fault-tolerant delay-insensitive asynchronous communication link with current-levelmonitoring is proposed for a highly reliable asynchronous Network-on-Chip system. Since
current is cut off when open faults on interconnection wires between transmitter andreceiver occur, the current level is getting increased at the transmitter. The current-levelmonitoring allows us to detect the interconnect fault with maintaining delay insensitivity.
The efficiency of the proposed link is compared under 0.13µm CMOS with a Triple Modular
Redundancy (TMR)-based asynchronous communication link. As a result, the energy
consumption and the number of wires of the proposed link are reduced to 57% and 33%,
respectively, in comparison with those of the conventional TMR-based one.

Naoki Kobayashi, Tohoku University, Japan

This paper gives an overview of our project on higher-order model checking and its
applications. Model checking is a technique for automatically checking whether a given
mathematical model satisfies a specification, and has been successfully applied to hardware
and software verification. Higher-order model checking is a generalization of traditionalmodel checking, where models are described as higher-order programs. Despite its extremely
high worst-case complexity, we have recently developed a practical higher-order model
checking algorithm that works well for typical inputs, and applied it to software verification.
We summarize our recent and ongoing work in the paper.

Rikizo Hatakeyama, Tohoku University, Japan

Based on nanoscopic plasma process control, we have created the following

Firstly, theoverwhelmingly-highest synthesis purity around 0.5% of atomic-nitrogen encapsulated C60(N@C60) is achieved toward a novel quantum-computer application. Secondly, an n-type thinfilm transistor is fabricated with Cs-encapsulated single-walled carbon nanotubes(Cs@SWNTs), which is very stable even in air, after long time soaking in water, and hightemperature heating (<400͠). Thirdly, Au nanoparticles are decorated with their size anddistance controlled on the surface of SWNTs toward novel applications of plasmonics-relatednano and bio electronics. Fourthly, a transfer-free method for growing graphene directly on a
SiO2 substrate is realized, and room-temperature selective edge functionalization and dopingof graphene is developed toward its practical applications.

Michio Niwano, Tohoku University, Japan

It is well-known that on anodization in a suitable electrolyte, the so-called “valve” metals
such as aluminum, tantalum, zirconium and titanium, undergo formation of porous anodic
oxides with self-ordered nano-tubular structures. Those self-ordered nanostructures may be
applied to various types of nano-electronic devices. We have fabricated low-power
single-electron-transistors (SETs), organic and dye-sensitized solar cells (SCs), gas- andbio-sensors, by using a hybrid process in which anodization (bottom-up process) for formationof nano-tubular anodic oxides is combined with the conventional photolithographic technique(top-down process). We demonstrate that self-ordered nano-tubular anodic oxides have thepotential to be used for high-performance nano-electronic devices.

coefficient of thermal expansion (CTE) of TiO2-SiO2 ULE glasses becomes zero. We
demonstrated that TiO2-SiO2 ULE glasses with zero-CTE temperature ranging from -70°C to

growth on B or P atomic layer formed on Si(100) or Si1-xGex(100) surfaces is achieved at below
500 °C. The tensile-strained Si epitaxial growth suggests that the low electrical activity iscaused by B clustering as well as the increase of interstitial B atoms and that tensile-strain
enhances P surface segregation and reduces the incorporated P amount around theheterointerface. These results open the way for group IV semiconductors with high mobility
as well as high carrier concentration by strain control for ULSIs using atomically controlled

Toward Voltage-Controlled Magnetic Tunneling Junctions with ZnO-relatedMaterials as Tunneling Barriers
Mohamed Belmoubarik, Sahashi Laboratory

Magnetic tunnel junctions (MTJs), composed of two ferromagnetic electrodes separated by athin insulating barrier layer, are currently used in spintronic devices, such as magnetic
sensors and magnetic random access memories. Recently, driven by demonstrations offerroelectricity at the nanoscale, thin-film ferroelectric barriers were proposed to extend thefunctionality of MTJs. Due to the sensitivity of conductance to the magnetization alignmentof the electrodes (tunneling magnetoresistance) and the polarization orientation in the
ferroelectric barrier (tunneling electroresistance), these multiferroic tunnel junctions(MFTJs) may serve as multi-state resistance devices controllable by external electrical field.
In this paper we propose another probe allowing the control of magnetoresistance (MR) withexternal electric field using ZnO-related materials as barriers.

Manetotransport Properties of Current-perpendicular-to-plane Exchange
Biased Spin Valves Based on Alternate Monatomic [Fe/Co]n Superlattices andAg with Fe Insertion Layer
JinWon Jung, Sahashi Laboratory

The bulk and interface spin scattering asymmetric coefficients, ǃF and ǄF/N, respectively, as
well as the interfacial specific resistance, AR*F/N, contribute to the total resistancechange-area product, ƦRA, in current-perpendicular-to-plane (CPP) geometry. The ǃF isrelated to spin polarization in the conductance of the F materials, while ǄF/N is related tospin asymmetric scattering of the spin-up and spin-down electrons at interface between the
ferromagnetic (F) and non-ferromagnetic (N) layers. Improved ƦRA values can be also be
achieved by increasing the AR*F/N ,which is crucial factor in influencing spin transport andmagnetoresistance, respectively, are large when compared to the band match between the F
and N interfaces as a spacer layer. We report the effect of the insertion of a 1 nm Fe layer into
F/N interfaces on the spin dependent transport properties. Using the Valet-Fert theory basedon the two-current model in which ƦRA is obtained as a function of thicknesses of theferromagnetic layer (3, 4, and 5 nm), we experimentally deduced the values of ǃF, ǄF/N, andAR*F/N of exchange-biased spin valves (EBSVs) for an artificially ordered B2 state Fe50Co50

Shun Kanai, Ohno Laboratory

We investigate the magnitude of the modulation of magnetic anisotropy in Ta/CoFeB/MgO
with various annealing temperatures and compositions. The perpendicular anisotropy field isenhanced (reduced) by applying negative (positive) gate electric field, and the magnitude ofmodulation depends on annealing temperature. The largest modulation is observed whenannealing temperature is around 225͠in all CoFeB-compositions. The ratio of 65 mT per 1

Electrons Spin Relaxation Anisotropy in Modulation-doped GaAs/AlGaAs Wires
Jun Ishihara, Ohno Laboratory

We investigated the electron spins relaxation of quasi-one dimensional electron gas inmodulation doped GaAs/AlGaAs quantum well by optical time-resolved Kerr rotation
measurement. It was shown that the spin dephasing time of electrons in a [110] oriented wire
structure is longer than 1 ns, while that of the electrons in a [-110] oriented wirestructure is
60 ps at a magnetic field 1 T and the temperature 5 K. This strong anisotropy of the spin
relaxation time indicates that the effective magnetic field due to the spin-orbit interaction ismostly cancelled for electrons moving along [110] orientation.

Excitonic Rabi oscillations in Self-assembled Semiconductor Quantum Dot
Utilizing Photon Echo Spectroscopy
Kenta Asakura, Edamatsu Laboratory

Semiconductor quantum dots (QDs) are promising candidates for solid-state quantum logic
devices since excitons in QDs have atom-like optical properties due to the three dimensional
confinement effects of the carriers. In this paper, we report on the experimental observationof the excitonic Rabi oscillations in self-assembled QDs by photon echo spectroscopy. The
observed oscillations showed anomalous behavior which was unexpected in two-levelsystems. We successfully reproduced the observed curves by a numerical calculation
including the local field effect (LFE). The agreement of the experimental and calculated
curves implies the importance of LFE on the coherent manipulation of the excitons in QDs.

between the biexciton and the cavity photon. We also found that the dephasing time of thebiexciton in the microcavity was faster than that of a bare CuCl thin film, indicating that thebiexciton-photon coupling is in a weak coupling regime.

Entanglement is one of the key resources in quantum information technology. Spontaneous

Fumihiro Kaneda, Edamatsu Laboratory

Entanglement has an essential role in quantum information and communication technology(QICT). The entanglement thus far applied to QICT has been pure and distillable
entanglement. Yet there is anothertype of entanglement, called “bound entanglement”, which
is not distillable by local operations and classical communication. We demonstrate theexperimental “activation” of the bound entanglement held in a four-qubit Smolin state,
unleashing its immanent entanglement in distillable form, with the help of auxiliary
two-qubit entanglement. We anticipate that it opens the way to a new class of QICT
applications that utilize more general classes of entanglement than ever, including boundentanglement.

Frequency-domain equalization (FDE) based on minimum mean square error (MMSE)
criterion is a powerful equalization technique for the broadband single-carrier (SC)transmission. However, the presence of timing offset produces the inter-symbol interference(ISI) and degrades the bit error rate (BER) performance. As the roll-off factor of the transmit

results show that loudspeaker arrangements above the listener generally result intransaural auditory displays that are less susceptible to head rotation.

Three Dimensional Auditory Display Using Ambisonics with Irregular
Loudspeaker Arrays
Jorge Treviño, Suzuki Laboratory
Virtual and augmented reality systems seek to realistically convey the presence of objects
and events that are not actually part of the user’s environment. The complex task involves
the precise stimulation of the user’s senses. We focus on the sense of hearing, and develop asystem capable of synthesizing three-dimensional sound fields. Our system is based on atechnique known as Ambisonics, which uses multi-channel loudspeaker arrays surrounding
the user. Typical Ambisonic systems do not work well if the loudspeakers are not uniformly
distributed in space. Our research introduces a new method to reproduce Ambisonics overirregularly distributed loudspeaker arrays.

Acoustic Privacy Technique Based on Simple Summation by Multichannel
Loudspeaker Array
Takuma Okamoto, Suzuki Laboratory

We propose a new speech privacy technique based on simple summation of numerous
N-channel loudspeaker signals. A speech signal is radiated from each loudspeaker withuncorrelated white/pink noise at a relative level that is higher than that of the speech.
Radiated speech sounds must have appropriate delay so that they are synchronized at asweet spot. At the sweet spot, SNR increases proportionally to N1/2. The speech signal at andaround the sweet spot is enhanced significantly, making it easily recognizable. Results ofcomputer simulations show that SNR and the speech intelligibility index (SII) increase
effectively only at and near the sweet spot.

Non-Invasive EMI-Based Fault Injection Analysis against Electrical Devices
Yu-ichi Hayashi, Sone Laboratory

In this paper, we introduce a new type of intentional electromagnetic interference (IEMI)
which causes information leakage in electrical devices without disrupting their operation ordamaging their physical structure. Such IEMI could pose a severe threat to a large number ofelectrical devices with cryptographic modules since it can be used for performing fault
injection attacks, which in turn allows for obtaining faulty outputs (i.e., ciphertexts) from
cryptographic modules and exploiting them to reveal information about secret keys. We
demonstrate fault injection attacks based on the IEMI through experiments using an
Advanced Encryption Standard (AES) module implemented on a standard evaluation board(SASEBO). The experimental results indicate that generating effective faults is feasible
and, therefore, such IEMI presents a tangible threat to many existing electrical devices andsystems that use cryptographic modules for secure communication and transactions.

FPGA Implementation of a Heterogeneous Multicore Processor with SIMD
Custom Accelerators
Hasitha Muthumala Waidyasooriya, Kameyama Laboratory

Heterogeneous multicore processors with CPUs and accelerators attract many attentions
since they can achieve power-efficient computing in various areas from low-power embedded
processing to high-performance computing. In this paper, we propose a heterogeneous
multicore processor with GPU-like SIMD accelerator cores. Although the functions of theaccelerator cores are similar to that of GPU, the accelerator architecture is simplified for
power-efficient computing. We also exploit the conﬁgurability of the FPGA to optimize thearchitecture for different applications. Experimental results with simple media processing
applications show that the proposed platform is 15 times power-efficient compared to the
GPU.

Towards Effective Load Distribution in Peer-Assisted Video Streaming
Mostafa M. Fouda, Kato Laboratory

Digital multimedia distribution technologies are expected to advance with 40G/100G
bandwidth, high speed disk drives, and Ultra High Definition Television (UHDTV). Alongwith these rapid improvements, some of the current protocols need to be reviewed in order toaddress these new aspects. The Peer-to-Peer (P2P) protocol is one of the most popular
techniques to download data, and watch TV-channels online and/or Video-on-Demand (VoD)
movies. In this work, we address the challenges involving large volume of video data
streaming using P2P, and propose an adequate solution towards effective load distribution in
peer-assisted video streaming.

Pure single-Photon Source for Quantum Information Processing
Ruibo Jin, Edamatsu Laboratory

We report the experiment of heralded pure single photon state generation in theprocess of spontaneous parametric down-conversion (SPDC) in KDP crystal. This pure single
photon state was utilized to interfere with a weak coherent state (local oscillator), without
the use of bandpass filters. This nonclassical interference can be applied to construct apolarization entangled state from independent sources. We tested the violation of BellCHSH-inequality with such entanglement source. Finally, this pure photon source was
employed in homodyne detection of the single photon state.

Simulation results confirm the superiority of proposed method thanleast square based linear estimation method.

5A-1: Symbolic Interaction in Sound and Music (Keynote)Gérard Assayag, IRCAM, CNRS, UPMC, France
The Music Representations team at Ircam has specialized in the symbolic processing ofmusical structures (Computer assisted music composition and analysis). Other teams at
Ircam and elsewhere have investigated issues related to musical digital signal processing or
to software architectures for real-time interaction. I call symbolic interaction the convergence
between these three paradigms : machine listening through low-level and perceptual signal
processing, symbolic computation of formal musical structures, live interaction based on
decisions taken on behalf of the resulting model. This idea renews the modality of live
interaction between musicians and computers in favor of a more complex setup than mereaudio effects or purely reactive actions from the computer. Sophisticated memory structures
may emerge in the interaction between the musician and the computer due to structural
feed-backs, thus shaping complex temporal architectures.

5A-2: High-accuracy Design and Implementation of All Pass-based Hilbert
Transformers and Fractional Delay Filters (Invited)
Georgi Stoyanov, Technical University of Sofia, Bulgaria
Fractional delay (FD) digital filters (fixed and variable) have been recently a subject of anever growing interest while Hilbert transformers (HT) are investigated since the dawn of thesignal processing. The problem with the design and implementation of both is that a highaccuracy of realization could be achieved at a price of complicated structures and a very hightransfer function order, leading to implementations with many hundreds of multipliers andprecluding a real-time tuning. In this work we propose several approaches to increase theaccuracy and to extend the frequency range over which the FD filter delay-time and the HTphase difference are near constant. These approaches are based on minimization of the phasesensitivity of the allpass structures used and to realizations of the multiplier coefficients in away, permitting tuning of the FD-time by changing very few parameters and making it
possible to be done in real-time. The complexity of the new structures is tens of times lower
than that of many new recently publicized realizations It is shown experimentally that the
FD filters and HTs so obtained are outperforming the other known realizations and they arevery suitable for different telecommunication applications.

Spatial Sound Systems
Yôiti Suzuki, Tohoku University, Japan

In future communications with a high sense-of-presence, the role of sound is extremely
important to enhance the quality and versatility of communications because sound itself canprovide rich semantic and emotional information. Moreover, sound (auditory information)
has good synergy effects with pictures (visual information). In this presentation, we
introduce our recent research results to capture and synthesize comprehensive 3D soundspace information as well as a high-definition 3D audio--visual display realizing strictaudio-visual synchronization. We believe that these systems are useful to advance universal
communications, which require particularly high-quality and versatile communications
technologies for all.

Takeshi Tokuyama, Tohoku University, Japan

We propose an efficient polynomial-time algorithm to find an optimal region with geometricshape-constraint in a pixel grid. This is an important function for image segmentation from a
digital picture. Compared with known methodology, our method can give constraint about
the shapes of segmented objects such that each object is decomposable into parts with simple
geometric shapes. In particular, we give an O(n^{1.5}) time algorithm for finding the optimal(maximum weight) region that is decomposable into line-monotone regions with given$k$ guide lines. We show some experimental results to show the feature of our image
segmentation function.

Recently, image matching/correspondence techniques achieving sub-pixel accuracy andhigher robustness against image noise have attracted significant attention in real-world
visual computing applications. This presentation provides a brief overview of advanced
machine vision technology using Phase-Only Correlation (POC) --- an efficient sub-pixel
image matching/correspondence technique using phase components in Discrete Fourier
Transforms (DFTs) of given images. Since 1990s, our group has carried out systematic
research and development of POC-based machine vision algorithms for various applications,where the term "machine vision" is used in a wider sense. In this presentation, wesummarize major research results obtained during our GCOE program.

Tatsuo Uchida, Tohoku University, Japan

High reality and highly functional display technologies have become important for
next-generation man-machine interface systems. To achieve this purpose, we haveinvestigated the accurate control method and evaluation method for light and established thepolarized light control (PLC) and the diffused light control (DLC) theories. From theseresults, we devised an incident-angle-independent, quantized-diffusion-angle (QDA) screen
and realized a high quality multiple directional viewing projection display system.
We also discuss a development of high-resolution 3D projection display with a liquid-crystal
shutter dividing an iris-plane for the next generation high quality display systems.

Masayuki Kawamata, Tohoku University, Japan

This paper reveals the class of digital filters with all second-order modes equal. We firstprove that if the second-order modes of a digital filter are all equal, the L2-sensitivity
minimization problem of the digital filter can be solved analytically. We derive a general
expression of the transfer function of digital filters with all second-order modes equal.
Furthermore, we show that the general expression is obtained by a frequency transformation
on a first-order prototype FIR digital filter.
