AIC Seminar Series

Advances in computational photography techniques for cultural, historic, and natural history materials

Carla Schroer and Mark MudgeCultural Heritage Imaging (CHI)

Notice:  Hosted by Richard Waldinger

Date:  Tuesday, May 29th 2012 at 4:00pm

Location:  EJ228 (SRI E building)  (Directions)


Our talk presents advances in robust new imaging tools from the emerging science known as Computational Photography. The common feature of the computational photography imaging family is the purpose-driven, selective extraction of information from sequences of digital photographs.

We will describe robust photography-based digital techniques for use with a wide range of cultural and natural history materials and associated research. We will show the use of these tools in a range of contexts including fine art conservation, research of museum and library collections, and documentation of rock art.

Examples of existing and cutting-edge uses of photography-based imaging will be presented, including Reflectance Transformation Imaging (RTI), Algorithmic Rendering (AR), and methods of image-based generation of textured 3D geometry.

   Bio for Carla Schroer and Mark Mudge

Carla Schroer is co-founder and director of Cultural Heritage Imaging (CHI) a California non-profit corporation based in San Francisco. Carla leads the training programs at CHI, along with working on field capture projects with Reflectance Transformation Imaging and related computational photography techniques. Carla also leads the software development and testing activities at CHI. She spent 20 years in the commercial software industry, managing and directing a wide range of software development projects including Sun MicrosystemsÂ’ Java technology, object oriented development tools.

Mark Mudge is President and co-founder of Cultural Heritage Imaging (CHI). Mark has a BA in Philosophy from New College of Florida. He has worked as a professional bronze sculptor and has been involved in photography and 3D imaging for over 20 years. He is a co-inventor, with Tom Malzbender, of the computational photography technique, Highlight Reflectance Transformation Imaging. He has published numerous articles and book chapters related to cultural heritage imaging.

Cultural Heritage Imaging is a 501(c)(3) non-profit corporation dedicated to the development and implementation of new imaging technologies for cultural, historic, and artistic heritage and scientific research. CHI is committed to the democratization of technology, relying on open source software and accessible methods and equipment.
