Abstract

Digital archiving of cultural heritage has heretofore focused on capturing accurate color information via spectral imaging. We review a means of capturing topographical information entitled reflection transformation imaging. This paper discusses an experiment that attempts to merge these two techniques. Several paintings were imaged and color accurate, interactive texture maps were generated. Experimental deficiencies are identified and suggestions are made for remediation. A new dual-imaging technique with improved capability is discussed. Our conclusion is that the simultaneous capture of high-accuracy spectral and textural information is entirely feasible.)
