 Elderly
Drivers

  • 3. Consequences
 Being
Pulled
over
 The
obvious
one
 Why
does
this
happen?

  • 6. What
are
road
signs
?
 



road
signs
are
signs
erected
at
the
side
of
roads
 to
provide
informa,on
to
road
users.
With
 increasing
speed
of
transport,
the
tendency
is
for
 countries
to
adopt
pictorial
signs
or
otherwise
 simplify
and
standardize
signs,
to
facilitate
 interna,onal
travel
where
language
differences
 can
create
barriers
and
in
general
to
reduce
the
 risks
in
driving

  • 7. PaLern
Similari,es

  • 8. The
purpose
of
having
a
RRS
in
your
car
 •  Safer
driving
 •  Building
autonomous
cars

 •  Teaching
people
good
driving
habits
 
 
 

 
 
 

Provide
driving
assistance

  • 9. The
Ini,al
project

  • 10. Results
 



The
implemented
algorithm
is
quite
fast,
the
 average
,me
for
detec,on
and
classificia,on
 of
signs
is
about
10
seconds
on
a
1
Ghz
 Turion64
processor
with
1Gb
of
RAM
running
 Fedora
Linux

STILL
NEEDS
TO
BE
OPTIMISED

  • 11. Work
in
Progress
 •  Building
the
Autoassocia,ve
Memory
(neural
 network
)
 •  Tes,ng
the
algorithm
on
video
 •  Implemen,ng
the
applica,on
on
an
iPhone

  • 12. What
are
associa,ve
memories?

  • 13. Recognising

a
camera
 •  Touch
screen

  • 15. Some
disadvantages...
 •  Poor
baLery
life
 Video
playback
is
10
hours
on
3GS

 •  Processing
power
 600Mhz
Processor
and
256
RAM
 Some
of
these
issues
might
be
sorted
out
when
 the
4G
comes
out

  • 16. Video
Implementa,on
 •  Mul,ple
frames
per
second
 •  Real‐,me
processing

  • 17. Why
work
on
videos?
 •  To
simulate
our
percep,on
of
driving

  • 18. Consciousness
 •  An
insight
to
how
vision
works
and
how
the
 brain
creates
consciousness

  • 19. But
the
idea
is...
 •  To
