Approximate svBRDF Estimation From Mobile Phone Video

Rachel A. Albert, Dorian Yao Chan, Dan B. Goldman & James F. O'Brien
We describe a new technique for obtaining a spatially varying BRDF (svBRDF) of a flat object using printed fiducial markers and a cell phone capable of continuous flash video. Our homography-based video frame alignment method does not require the fiducial markers to be visible in every frame, thereby enabling us to capture larger areas at a closer distance and higher resolution than in previous work. Pixels in the resulting panorama are fit with a BRDF...
