Height from photometric ratio with model-based light source selection

William A. P. Smith, Fufu Fang

Abstract: Highlights•New photometric stereo method that recovers surface height directly.•Propose a model-based approach to selecting and removing noisy observations.•Exploit photometric ratios to express height recovery as a large sparse linear system of equations.•Evaluate quantitatively and qualitatively on wide range of objects including shadows and specularities.
