Training for innova-on: data and mul-media visualiza-on
Roberto Scopigno Visual CompuDng Lab, CNR-‐ISTI, Pisa, Italy
Ariadne -‐TNA • EU INFRA “ARIADNE” acDvity on Visual Media: – Workshop: “Ariadne infrastructure for Mul2media data: matching technologies and user needs” (Pisa, Oct. 7-‐8, 2013)
– Review of 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
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
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
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
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)
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
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)
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…
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)
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)?
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
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?
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) h_p://vcg.is-.cnr.it/3dhop/
3DHOP – Visual data on the web Hi-‐res Single Viewer (component) Collec-on Viewer (component)
More complex example:
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
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

Visual Media service: what about terrains/GIS?
Work ongoing at ITABC-‐CNR
3D Cloud Services -‐ ITABC Cloud Services for 2D/3D Landscapes • Cloud service for upload / management of processing data (DEMs, Geo-‐images,
shapefiles, etc.) with flexible and customizable access policies • Large 3D Terrain datasets generaDon as
web service (also accessible from mobile devices)
• 2D interacDve maps (web components)
• Cloud Composing services to create collaboraDve gis-‐based 3D reconstrucDons
Output • 3D datasets opDmized for real-‐Dme
visualizaDon and web streaming • Different output formats (disseminaDon)

Roadmap • We are now tesDng it… • Deliver to Ariadne partners for use, assessment and test [Dec 2014]
• Future work: – Add support for more data file types (2D, 3D) – Support for HDR images (CNR-‐ISTI) – Support for massive data items uploading (batch) – Enhanced support for terrain models (CNR-‐ITABC)
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! (next ediDons in summer 2015)
