FRINGEREMOVAL - Fringe removal and noise reduction from absorption images.
Creates an optimal reference image for each absorption image in a set as
a linear combination of reference images, with coefficients chosen to
minimize the least-squares residuals between each absorption image and
the optimal reference image. The coefficients are obtained by solving a
linear set of equations using matrix inverse by LU decomposition.
Application of the algorithm is described in C. F. Ockeloen et al, Improved
detection of small atom numbers through image processing, arXiv:1007.2136 (2010).
