+    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).
