The Collaboration• Formal joint laboratory (IPAL)• Collaborators:

– CNRS: Talent, $, students– NUS SOC: Talent, $, students– I2R: Talent, students

• Results: Jointly owned novel image processing methods and applications.

Hide Existence of Files• Defeat even attacker who:

– is familiar with system– has full access to sytem– lacks only the file access key

• Applications:– External data/storage &

managed services– Military & financial, where

data is so valuable that coercion is likely

StegFS: Steganographic File System

Doesn’t even want himto know the file exists!

The Collaboration

• Joint project• Collaborators

– NUS SOC (Talent, student)– I2R (Talent)

• Results: Jointly owned IPs on StegFS

Benefit Children

• Childhood leukaemia is a heterogeneous disease

• Treatment is based on subtype

• 3 different tests and 4 different experts are needed for diagnosis

Curable in USA, fatal in Indonesia

A single platform diagnosisbased on gene expression

The Collaboration• Joint project• Collaborators:

– St. Jude Children’s Research Hospital (data, diagnosis, $)– I2R (gene expression analysis)

• Results: – Clinical outcomes: owned by St. Jude– Algorithmic outcomes: owned by I2R

One Step Closer to Omnipresence• Wanted: A system of

networked wireless sensors carried on autonomous mobile nodes that are able to operate in all kinds of terrain

• Challenge: To integrate– localization systems– mobile ad hoc networking– distributed robotics.

The All Terrain Advanced Network of Ubiquitous Mobile

Asynchronous Systems

The Collaboration• Informal ad hoc collaboration• Collaborators:

– UC Davis (localization, mobile ad hoc networking)– CMU, U. of Tokyo, NUS (distributed robotics)– I2R (mobile ad hoc networking)

• Results: – Joint papers only– No IPs expected

Better Phone Service for Remote Arctic Villages• Ad hoc networking for the

Village Radio system in Canadian arctic

• Energy-efficient routing protocol to improve the Village Radio system

• Multi-path for robustness • Protocol learns routes

from packets transmitted• QoS beyond best effort

through multi-path routing

The Collaboration

• Stimulate scientific & tech. collab. between S’pore, Alberta, & the rest of Canada by:

– build research capabilities

– train graduates in ICT

– develop new tech

– promote collaboration among industry partners of two countries

• R&D Consortium• Collaborators

– TRLabs (talent, $)– I2R (talent, $)

• Results– owned by TechnoBridge,

which is itself owned by A*STAR and TRLabs

= +

Promote robustness of crypto techniques (e.g., digital signature) from fragile level to non-fragile level, in order to meet needs of

media storage and transmission over lossy channels.

Protect Authenticity of Data in a Robust Way

Altered?

Who signed?

The Collaboration• Joint project• Collaborators:

– Columbia University (talent, students)

– I2R (talent, students)

• Results: – Media authentication:

jointly owned– Object authentication:

owned by I2R

Let Machines Perceive as We Do• Perceptual visual quality according

to characteristics of human vision

• Outperform metrics in ITU-T VQEG test

• Adoption in video coding results in efficiency & quality improvement (other systems make compromise betw. the two)

Higher PSNR!

New perceptual metric perceives correctly.

0.810.83New metric

0.690.66PSNR metric

Spearman Correlation

Pearson Correlation

Comparison with MOS (Mean Opinion Score)

Better accuracy Better consistency

The Collaboration

NTT DoCoMo R&D Center

• Joint Project• Collaborators:

– NTT DoCoMo (data generation, subjective tests, $)

– I2R (new methodology)

• Results: – Visual quality evaluation for

mobilecom: jointly owned– Quality gauge from partial

data: owned by I2R– s/w embedded in DoCoMo’s

coding system: owned by DoCoMo

Collaboration Models

• Partners put in tech, people, and/or $• I2R puts in tech and/or peope• Each retain their background IP• Foreground IP can be jointly own or split by

agreement
