Mathematical derivation for Vora-Value based filter design method: Gradient and Hessian (2009.13696v2)
Published 29 Sep 2020 in math.OC and cs.CV
Abstract: In this paper, we present the detailed mathematical derivation of the gradient and Hessian matrix for the Vora-Value based colorimetric filter optimization. We make a full recapitulation of the steps involved in differentiating the objective function and reveal the positive-definite Hessian matrix when a positive regularizer is applied. This paper serves as a supplementary material for our paper in the colorimetric filter design theory.
