The Graphics Imaging & Light Measurement lab develops new imaging techniques and analysis algorithms in Computer Graphics and Vision for applications in Bio-Diversity, Bio-Medical Research and Archaeology.

The recent influx of affordable optics-based imaging technology is making a wide range of new data formats available to researchers for scientific analysis of real objects. As these technologies become more prevalent, scientists are discovering the need for new forms of investigation never before considered in computer graphics research. These examples are opportunities to re-think a number of problems in computer graphics and develop new ways of seeing, representing and navigating information.


Graphics Develop algorithms to process, visualize and analyze complex datasets from multiple imaging modalities.

Imaging Capture the shape and physical appearance of objects under multiple lighting parameters and across multiple spectral bands.

Light Measurements Lab Measure physically-based material light reflectance models and record the spectral distribution of light sources.


iDigFossils: 3D Printing & Scanning

Develops multi-spectral imaging and 3D printing techniques for analyzing complex shapes and materials. Collaborators include the UF College of Education and The Florida Museum of Natural History.


iDigBio: Digitizing and Analyzing Bio-Diversity

Develops non-invasive optical capture techniques and rendering algorithms to digitize biological specimens from rare collections.

Thera Frescos

Reassembling the Thera Frescos: Practical Acquisition Systems

Introduces hardware and software systems to assists archeologists at the Akrotiri Laboratory of Wall Paintings reconstruct the Thera Frescos.


RGBN: Non-Photorealistic Rendering for Scientific Illustration

Investigates  non-photorealistic illustrations that reveal subtle surface detail using RGBN Images that store  per pixel color and a surface normals.
