• EU
INFRA
“ARIADNE”
acDvity
on
Visual
Media:
– Workshop:
“Ariadne
infrastructure
for
Mul2media
data:
matching
technologies
and
user
needs”
(Pisa,
Oct.
7-­‐8,
2013)
– Review

visual
media
use
in
current
archeology
archives
and
working
pracDces
– OrganizaDon
of
the
first
TNA
on
Visual
Media
(Pisa,
June
23-­‐27,
2014)
• Full
Dme
week
on
the
subject,
lessons
and
pracDcal
acDvity
• PresenDng
services
and
resources
developed
by
Ariadne
technical
partners

3. Ariadne
-­‐TNA
Other
TNAs
organized
in
Y2:
• TNA
on
“Mapping
exis+ng
datasets
to
CIDOC-­‐
CRM”,
hosted
by
PIN
in
Prato,
on
26-­‐30
May
2014
– Goal:
implement
conceptual
mappings
and
data
conversions
of
their
exisDng
datasets
to
the
CIDOC
CRM
ontology
• TNA
on
“Design
of
archaeological
datasets”,
held
at
CNR-­‐ISTI
Pisa,
July
14-­‐18,
2014.
– Goal:
design
archeological
datasets
endowed
with
rich
seman-cs
and
allow
seman-c
interoperability

4. The
ARIADNE
“popula-on”
• Data
providers
/
users
– ApplicaDon-­‐related
knowledge,
consolidated
experience
on
current
working
procedures
– Data
owners,
experDse
on
conservaDon/access
management
• Technology
providers
– Experience
on
designing
and
using
innovaDve
tools
for
visual
media
producDon,
delivery
and
visualizaDon
– Role:
disseminaDon
of
knowledge
on
new
technologies,
technology
advisors

5. Visual
Media
– Visual
Media
Data:
any
type
of
visual
representaDon
of
Archaeological
findings
or
assets,
i.e.:
• Standard
2D
images
(high-­‐res!)
• Advanced2D
images
(PTM,
RTI,
panoramic
images,
HDR)
• 3D
models
(single
or
complex
scenes)
• Videos
• GIS
data

6. Goals
of
the
TNA
on
2D/3D
media
• General:
enable
scholars
and
professionals
to
endorse
and
implement
modern
approaches
for
the
visual
mulDmedia
documentaDon
of
artworks
and
archaeological
sites
(i.e.
fieldworks
and
artefacts)
• More
specifically:
pair
classical
frontal
lessons
with
a
more
pracDcal
acDvity
(hands-­‐on
experience
on
the
technologies
presented)

7. Goals
of
the
TNA
on
2D/3D
media
• Prac-cal
ac-vity:
– We
solicited
parDcipants
to
submit
specific
problems
and
test
cases
they
are
working
with
– These
test
beds
were
an
important
criterion
in
the
selecDon
of
the
parDcipants
– Program
of
the
school
included
Dme
dedicated
to
advising
the
students
on
the
pracDcal
hands-­‐
on
experience
and
in
their
proposed
case
studies

8. Selected
students
• Eleven
parDcipants
– 9
were
assigned
an
ARIADNE
fellowships
and
2
come
at
their
expenses
– from
several
different
countries
(ArgenDna,
Belgium,
Estonia,
Germany,
Greece,
Italy,
Netherlands,
UK)
– Holding
a
mixed
background
(in
the
majority
a
human
science
background,
only
a
few
holding
an
engineering
degree)

9. Lesson
learned
(WS
&
TNA)
• Good
experience
in
produc-on
of
visual
media
(mostly
2D,
but
also
some
high-­‐profile
3D
acDvity)
– CNR
offers
support
in
this
acDvity
(open
source
tools)
• Cri-cal
issue:
Archival
and
Access
to
visual
media…

10. Lesson
learned
(WS
&
TNA)
• 2D
images
are
stored
and
integrated
with
in
Ariadne
partner’s
archives
/
databases
• 3D
models
are
sDll
isolated
resources
• Access
is
the
problem:
– SDll
managed
as
“data
files”
– Approach
used:
• NoDfy
existence
of
the
data
file
of
a
visual
media
resource
• User
downloads
the
file
(Dme
lag)
• User
needs
to
have
an
applicaDon
for
managing
that
file
type
(error
messages)

11. Lesson
learned
(WS
&
TNA)
Problems
with
data
file
approach:
• Explicit
download
and
file
size
– Files
of
visual
media
assets
are
usually
large/huge
• 2D
image
in
high-­‐res
(40Mpixels)
è
120MB
uuncompressed,
15
MB
lossy-­‐compressed
• 3D
model
(scanned)
is
mulit-­‐million
triangles/samples
è
from
50MB
to
GBs
– Should
we
wait
for
enDre
file
transfer
comple-on
before
looking
into
the
data
(and
discover
that
is
not
the
one
we
are
searching
for)?

12. Lesson
learned
(WS
&
TNA)
Problems
with
data
file
approach:
• Once
file
is
on
local
disk,
do
I
have
an
applicaDon
to
open
it?
– Many
different
file
types
(easier
with
images,
highly
complex
with
3D
models)
– The
deprecated
error
message:
• Unrecognized
file
type

13. Modern
access
to
visual
data
• The
web
is
the
channel:
– Click
and
immediately
inspect
the
data
– Inside
current
web
page
or
into
a
new
one
– Using
your
favourite
web
browser
– Possible
with
many
visual
media
using
WebGL
and
modern
support
to
data
– How
can
we
help
our
community
to
integrate
those
technologies
in
exis+ng
archives
/
databases?

14. 3DHOP
–
Visual
data
on
the
web
• PresentaDon
/Publishing
3D
content
on
web:
– 3D
visualiza-on
on
web
pages
is
now
possible
with
WebGL
&
SpiderGL
– 3D
data
&
visualizaDon
become
part
of
the
web
page
– Simplify
the
producDon
of
web-­‐based
presenta-ons
or
installa-ons
using
CNR’s
“3DHOP”
(3D
Heritage
Online
Presenter)

16. New
ARIADNE
services
for
visual
data
Our
idea:
• For
each
visual
media
asset:
– The
user
fills
a
simple
form
and
uploads
the
data
file
– An
automa-c
service
on
the
ARIADNE
server
will
open,
convert,
transform
in
a
browsable
page,
send
in
output
the
URL
(or
a
.zip
file)
to
the
user
– The
user
links
the
media
asset
in
his
archive
using
the
provided
URL

17. New
ARIADNE
services
for
visual
data
Which
media
types?
• 3D
models
• High-­‐resoluDon
2D
images
• ReflecDon
TransformaDon
Images
(RTI)
• [High
Dynamic
Range
(HDR)
images]
For
all
of
them
(technology):
• MulD-­‐resoluDon
encoding,
progressive
transmission,
nearly
immediate
visualizaDon

• Future
work:
– Add
support
for
more

(2D,
3D)
– Support
for
HDR
images
(CNR-­‐ISTI)

30. Conclusions
• Our
first
experience
of
TNA
under
the
ARIADNE’s
umbrella
• Several
technological
instruments
presented
extensively,
on
real
archaeological
examples
and
with
prac-ce
• Feedback
gathered
instrumental
to
the
design
of
first
Ariadne
services
for
visual
media
• Stay
tuned
with
ARIADNE
training
program!
