Accurate recovery of a specularity from a few samples of the reflectance function

We present a new technique for estimating the specular peak of the bidirectional reflectance distribution function (BRDF) based on finite rate of innovation (FRI) sampling. The specular component of the BRDF varies rapidly, so it is challenging to acquire it by point-wise sampling. Yet, the knowledg…
