Algebraic Models for Accurate LFS Reconstruction

In this paper, we analyze four algebraic models for light fall off representation. The algebraic models are estimated using fitting techniques of non-linear models. The alternative light attenuation models are then evaluated in a 3D reconstruction method. The comparative analysis of the 3D reconstruction error is presented and shows that the algebraic models are more accurate. The advantages and disadvantages of the alternative models are discussed and compared with the traditional representations of light fall off known as the inverse square law.
