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
Doesn’t even want him
to know the file exists!
• Applications:
– External data/storage &
managed services
– Military & financial, where
data is so valuable that
coercion is likely
StegFS:
Steganographic File System
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 diagnosis
based 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

Who
signed?
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.

Let Machines Perceive as We Do
• Perceptual visual quality according
to characteristics of human vision
Higher PSNR!
New perceptual metric perceives correctly.
Comparison with MOS (Mean
Opinion Score)
• Outperform metrics in ITU-T
VQEG test
• Adoption in video coding results in
efficiency & quality improvement
(other systems make compromise
betw. the two)
