An Optimal Experimental Design Approach for Light Configurations in Photometric Stereo
Hamza Gardi, Sebastian F. Walter, Christoph S. Garbe
This paper presents a technique for finding the surface normal of an object from a set of images obtained under different lighting positions. The method presented is based on the p…
Higher-order derivatives of the QR and of the real symmetric eigenvalue decomposition in forward and reverse mode algorithmic differentiation
Sebastian F. Walter, Lutz Lehmann, René Lamour
We address the task of higher-order derivative evaluation of computer programs that contain QR decompositions and real symmetric eigenvalue decompositions. The approach is a combin…
Algorithmic Differentiation of Linear Algebra Functions with Application in Optimum Experimental Design (Extended Version)
S. F. Walter, L. Lehmann
We derive algorithms for higher order derivative computation of the rectangular and eigenvalue decomposition of symmetric matrices with distinct eigenvalues in the forward and…
Efficient Higher Order Derivatives of Objective Functions Composed of Matrix Operations
Sebastian F. Walter
This paper is concerned with the efficient evaluation of higher-order derivatives of functions that are composed of matrix operations. I.e., we want to compute the -th deriv…
