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.


iDigBio: Digitizing and Analyzing Bio-Diversity

Develops non-invasive optical capture techniques and rendering algorithms to digitize biological specimens from rare collections at the American Museum of Natural History Vertebrate Paleontology and Mammalogy collections as well as the Duke University Lemur Center, Fossil Primates Division.

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. This is an ongoing collaboration with researchers from Princeton University, University College London and Katholieke Universiteit Leuven, along with archaeologists from the Akrotiri Excavation and the University of Ioannina.


RGBN: Non-Photorealistic Rendering for Scientific Illustration

Investigates the creation of non-photorealistic illustrations from a type of data lying between simple 2D images and full 3D models: images with both a color (albedo) and a surface normal stored at each pixel. The project introduces methods for signal processing, scale-space analysis, derivative estimation, and segmentation. We present analogues of stylized rendering techniques such as toon shading, line drawing, curvature shading, and exaggerated shading and new stylization effects based on multiscale mean curvature shading, as well as fast discontinuity shadows.

Project Comming Soon


Multi-Spectral Imaging and Physically-Based Appearance Modeling Optical Imaging Devices for Bio-Medical Research


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.
