Software

This software is available for noncommercial, educational, scholarly, and/or charitable purposes only

Software in support of this research program is posted here. Most of this will be executable MatlabTM, which requires Matlab's compiler runtime. The specific version required is either R2014b (version 8.4) or R2016a (version 9.0.1). The 2014b software may not run on El Capitan MacOS.

X-rite ColorChecker Digital SG (CCSG) Evaluation

The CCSG is often used to build and evaluate camera color profiles. This software evaluates the colorimetric accuracy of the CCSG contained in an image. The zip file contains executable Matlab, instructions, reflectance data of CCSG, test image, example output, and source code.

MultiSpectralTools – Dual-RGB Processor

Collecting a pair of RGB images using different colored filters or lights can be used for spectral estimation and improving color accuracy compared with an RGB camera. This approach has been patented by RIT and commercialized by Flux Data and Sinar. Over a number of years, we have been improving our software. This is the March 2016 version. It runs on 16-bit linear Tiff and Sinar DNG file formats.

SpectralPicker

MultiSpectralTools has both colorimetric and spectral workflows. The file format is a nine-channel tiff, where the top RGB are color managed and the bottom six are the multi-spectral channels. These channels are used to display the average spectral reflectance factor of a user-defined circular aperture moved about the image. The colorimetric data, spectral data and a spectral reflectance factor plot can be saved if desired.

Four-Light Imaging Simple

Collecting images from four different lighting geometries enables calculating diffuse and surface normal maps. These maps can be used to render paintings and drawings for archiving and reprographics. When stored in .pfm format, our software ArtViewer can be used for real-time viewing. The program runs on several file formats including 16-bit linear Tiff and Sinar DNG.

ArtViewer

This program is similar to the RTI Viewer. It uses files generated using the Four-Light Imaging Simple software.

Convert DNG to Tiff

This program converts DNG format to linear Tiff. It is based on DCRAW (https://www.cybercom.net/~dcoffin/dcraw/). The zip file contains executable Matlab and source code.

Bit Depth Evaluation and Assignment

Sometimes following a conversion of a raw format to unassigned tif, the image appears very dark, a result of the sensor having a lower bit depth than 16 bit. This program evaluates and reassigns bit depth.

Convert CR2 to Tiff

Many CR2 to Tiff converters add a tone curve. This program maintains linearity. It is based on DCRAW (https://www.cybercom.net/~dcoffin/dcraw/). The zip file contains executable Matlab and source code.

Convert Monochrome CR2 to Tiff

We had a Canon Mark III converted to monochrome. The zip file contains executable Matlab and source code. (We get better results using AccuRaw Monochrome.)
