Abstract

In this paper, a new Minimum Description Length (MDL) approach for the characterization of a mobile phone's color camera is presented. The use of high-order polynomials, Fourier sine series, and artificial neural networks (ANN) for solving this problem are compared and contrasted. The MDL formalism is used for determining the stochastic complexity of polynomial and Fourier sine models for the characterization of a Nokia N93 mobile phone camera. A quantitative evaluation of their performances, as well as for using an ANN, is provided.
