Tom Malzbender

Research Scientist & Independent Technology Consultant

Tom Malzbender is a researcher working at the intersection of computer vision, imaging and 3D graphics. During his 31 years at Hewett-Packard Laboratories, Tom developed the techniques of Reflectance Transformation Imaging (RTI) and Polynomial Texture Mapping (PTM)—now extensively used for seeing detail on the surface of archaeological artifacts, as well as in forensics and palaeontology. Tom also developed Fourier Volume Rendering used in medical imaging, as well as the capacitive sensing technology leading to HP’s entry into the graphics tablet market. He is on the boards of Cultural Heritage Imaging and Alacrity and collaborates on imaging research at Stanford University. He is an avid rock climber, holding several first ascents in Yosemite and the Sierra. For more information on Tom’s work, please refer to
