Bruce Lamond, Pieter Peers, Abhijeet Ghosh, Paul Debevec: “Image-based Separation of Diffuse and Specular Reflections using Environmental Structured Illumination”

April 16, 2009 | San Francisco, CA

Speaker: Bruce Lamond, Pieter Peers, Abhijeet Ghosh, Paul Debevec
Host: IEEE International Conference on Computational Photography

We present an image-based method for separating diffuse and specular reflections using environmental structured illumination. Two types of structured illumination are discussed: phase-shifted sine wave patterns, and phase-shifted binary stripe patterns. In both cases the low-pass filtering nature of diffuse reflections is utilized to separate the reflection components. We illustrate our method on a wide range of example scenes and applications.
