A method for estimating light direction, shape, and reflection parameters from a single image

Rahman, Sejuti; Robles-Kelly, Antonio


This paper presents a novel approach for estimating light direction, shape, and reflectance parameters from a single image based on iterative optimisation. We depart from a generalist view of the reflection process based upon a physical interpretation and cast the recovery of the reflection parameters in an optimisation setting. With the estimated specular reflectance parameters, we recover the light source direction from specular highlights while applying two novel constraints, coplanarity and...[Show more]
