We present a simple imaging method that can provide improved… Expand
IMAGING FOSSILS USING REFLECTANCE TRANSFORMATION AND INTERACTIVE MANIPULATION OF VIRTUAL LIGHT SOURCES
Many fossils cannot be fully illustrated using a setting of physical light sources, and conventional photographic approaches are therefore insufficient. Polynomial texture mapping (PTM), a newExpand
Virtual whitening of fossils using polynomial texture mapping
TLDR
A new, simple method is described for transforming PTM files that mimics whitening, a traditional procedure for fossil photography, based on the estimation of surface normal vectors from the PTM coefficients that are used to construct a diffuse, isotropic lighting model that is only dependent on local surface slope. Expand
Reflection transformation imaging on larger objects: an alternative method for virtual representation
TLDR
A new low-cost system for producing high quality PTMs of medium-large objects, from 60-70 cm of width by 50-60 cm of height up to 2m of widthBy 1m of height is presented and a novel software to browse huge resolution PTMs is presented. Expand
Polynomial texture mapping and related imaging technologies for the recording, analysis and presentation of archaeological materials
Polynomial Texture Mapping (PTM; Malzbender et al 2001) uses multiple images to capture the reflectance properties of a given surface. Multiple captures may be combined in order to produceExpand
Reflectance transformation imaging (RTI) of a little known southeastern copper plate
TLDR
A case study using reflectance transformation imaging (RTI) on a copper plate from Chauga (38OC47) in Oconee County, South Carolina, that was not amenable to other imaging techniques, found that RTI provided a way to record new digital artifact data thus providing new information about the plate. Expand
Archaeological applications of polynomial texture mapping: analysis, conservation and representation
TLDR
Through examples developed by the University of Southampton in partnership with a range of UK and international bodies, the benefits of Polynomial Texture Mapping are demonstrated in the areas of archaeological analysis, conservation and representation. Expand
High Quality PTM Acquisition: Reflection Transformation Imaging for Large Objects
TLDR
The aim is to analyze the acquisition pipeline, resolving all the issues related to the size of the object, and the conditions of acquisition, and present a new tool to interactively browse high resolution PTMs. Expand
Reflectance Transformation Imaging (RTI) of saw marks on bones
TLDR
RTI was found to be excellent for visualizing tool mark on bones, though it was more successful in capturing shallow surface details versus deeper alterations, and overall RTI is relatively inexpensive, easy to perform, and effective for imaging alterations on bones. Expand
Applications of Reflectance Transformation Imaging (RTI) to the study of bone surface modifications
TLDR
Reflectance Transformation Imaging is presented as a viable tool in the analysis of worked bone production technologies and use-wear, as well as post-depositional processes and conditions for identifying specimens that require more detailed analysis or higher resolution imaging. Expand
Reflectance Transformation Imaging Systems for Ancient Documentary Artefacts
TLDR
This paper discusses the interim results of the AHRC RTISAD project, which has developed and tested a range of techniques for gathering and processing reflectance transformation imaging (RTI) data and identifies on-going software development work of value to the broad EVA community and proposes further enhancements.
