Eastern Analytical Symposium and Exhibition (EAS)
1. “Structure from Motion/Photogrammetry and the Long-term, Archival Survival of 3D Information” (Oral Presentation)
This talk by Mark Mudge is part of the session “Analytical Imaging for Cultural Heritage Part I,” organized in cooperation with the New York Conservation Foundation.
Somerset, New Jersey: Tuesday, November 19, 2013, 10:20 am
2. “The Emergence of Computational Photography: Interpretation, Measurement, and the Quantification of Surface and Material Property Change” (Oral Presentation)
This talk by Mark Mudge and Carla Schroer is part of the session “Analytical Imaging for Cultural Heritage Part 2,” organized in cooperation with the New York Conservation Foundation. The presenters describe Computational Photography, which extracts and synthesizes information from image sequences to create a new type of image containing information not found in any single image in the sequence. Examples of the existing and cutting-edge uses of photography-based imaging are explored. The presentation discusses computational photography tools: Reflectance Transformation Imaging, Algorithmic Rendering, Structure from Motion Photogrammetry and Multispectral imaging. New research from Princeton University, Simon Fraser University, and the Georgia O’Keeffe Museum demonstrates how these techniques can be used to track changes in object surfaces. We also explore the necessity for transparent evalaution of scientific digital representations. The goal is to establish the conditions under which a “real world” subject can be digitally represented as a “digital surrogate”, which can reliably serve as a digital stand-in for subsequent scientific or scholarly examinations. Computational photography tools lend themselves to meeting these requirements.
Somerset, New Jersey in the Bedminster Room at the DoubleTree Hotel: Tuesday, November 19, 2013, 2:00 pm
3. “Practical, Scientific Use of Photogrammetry and Structure from Motion Technologies in Cultural Heritage” (One-Day Course)
This short course by Mark Mudge discusses how to produce scientific 3D digital representations and synergies possible with related computational photography techniques. The course explores how photographic sequences of a subject can be captured according to principles that maximize the available information from a series of viewpoints to yield the best results. We see how these software platform-independent rule-based data sets can be transformed into 3D representations and confidently reused by others both now and in the future.
Somerset, New Jersey: Course #E-13-31: Wednesday, November 20, 2013, 8:30 am–5:00 pm
2013 International Rock Art Congress (IFRAO)
“Advances in computational photography techniques for scientific rock art recording and analysis; Reflectance Transformation Imaging (RTI), Algorithmic Rendering (AR), and Structure from Motion (SFM) Photogrammetry” (Workshop in 2 Parts)
This workshop in two one-hour segments was presented by Carla Schroer and Mark Mudge from Cultural Heritage Imaging (CHI), with contributed material from Tommy Noble and Neffra Matthews from the US Bureau of Land Management. The workshop examined the robust new empirical capture and analysis tools Reflectance Transformation Imaging (RTI), Algorithmic Rendering (AR), camera calibration, and image-based Structure from Motion (SFM) generation of textured 3D geometry. These techniques were explored in the context of the emerging science of “Computational Photography”. Computational Photography extracts and synthesizes information from image sequences to create a new type of image containing information not found in any single image in the sequence. Examples of existing and cutting-edge uses of photography-based imaging were presented.
Albuquerque, New Mexico: Thursday, May 30, 2:30–3:30 pm (break between hours: 3:30–4:00 pm) and 4:00–5:00 pm
Note: This two-hour workshop could be attended for one or both hours.
Hour 1: Thursday, May 30, 2:30-3:30 pm – Reflectance Transformation Imaging (RTI) and related technologies.
In the first hour, the workshop presenters showed examples from inscriptions, rock art, manuscripts, and lithics. They also provided an overview of the free RTI software, along with a demonstration of the RTI photographic capture sequence, using standard digital photographic equipment. New developments in the related technology Algorithmic Rendering (AR), which uses the same data sets as RTI, were also presented. (Followed by a half-hour break.)
Hour 2: Thursday, May 30, 4:00–5:00 pm – Scientific Imaging requirements and Photogrammetry.
In the second hour, the presenters explored the necessity for transparent evaluation of scientific digital representations, with examples of rock art and related sites documented using the SFM photogrammetry technique.
WAC-7 Seventh World Archaeological Congress
1. “Computational photography: tools for digital archaeology” (Presentation)
This talk by Mark Mudge and Carla Schroer presents advances in robust new digitization tools from the emerging science “computational photography.” Computational photography extracts and synthesizes information from image sequences to create a new type of image containing information not found in any single image. The talk will present examples from Reflectance Transformation Imaging (RTI) and Algorithmic Rendering (AR). These techniques are being widely adopted by art museums and are especially valuable for examining fine surface details of objects. Examples include inscriptions, rock art, manuscripts, and lithics. These techniques can be used with standard digital photography equipment and open-source software.
The Dead Sea, Jordan: Session 2.2B, “Archaeology in the Digital Age”: Tuesday, January 15, 2013, 1:00 pm–3:00 pm
2. “The necessity of transparency in scientific digital documentation” (Presentation)
This talk by Mark Mudge and Carla Schroer will explore the necessity for transparent evaluation of digital tools and methods used for the scientific documentary imaging of “real world” subjects, where the goal is to produce a digital stand-in (digital surrogate) that can be used for subsequent scientific or scholarly examinations. The presentation will show how a “digital lab notebook” enables this transparency using the example of the methodology and software for Reflectance Transformation Imaging (RTI). The presentation examines key factors that determine whether a technology can practically build a digital lab notebook and the implications for the scientific and transparency needs of the cultural heritage community.
The Dead Sea, Jordan: Session 5.1G, “The Integration and Management of Archaeological Datasets”: Friday, January 18, 2013, 8:00 am–10:30 am
