General:
L. Meylan, Tone mapping for high dynamic range images, Ph.D. Thesis, 2006.
The algorithm used in this programme is a modified form of that described in:
L. Meylan, D. Alleyson, S.Süsstrunk, A model of retinal local adaptation for the tone mapping of CFA images, accepted for Journal of the Optical Society of America, 2007
Adaptation to wide-ranging luminance is based on a modification of the model from:
K. I. Naka, W. A. H. Rushton, S-potentials from luminosity units in the retina of fish(cyprinidae). Journal of Physiology, 185:587-599, 1966.

Implementation:
For speed, this programme uses recursive separable Gaussian filtering as described in:
J. M. Geusebroek, A. W. M. Smeulders, J. van de Weijer, Fast anisotropic Gauss filtering, IEEE Transactions on Image Processing, Vol. 12, No. 8, 2003
which follows:
I. T. Young, L. J. van Vliet, Recursive implementation of the Gaussian filter, IEEE Transactions on Signal Processing, vol. 44, pp. 139-151, 1995
with improved constants taken from:
I. T. Young, L. J. van Vliet, M. van Ginkel, Recursive Gabor filtering. IEEE Transactions on Signal Processing, vol. 50, pp. 2799-2805, 2002.

Retinex:
Multi-Scale-Retinex with Color Restoration used in some commercial products and which also inspired earlier work by the group at EPFL is described in:
Z. Rahman, D. J. Jobson, G. A. Woodell,Retinex Processing for Automatic Image Enhancement, Journal of Electronic Imaging, 13(1), pp. 100-110, 2004.
Retinex methods unfortunately produce computational artifacts at sharp edges in the image and tend to lose colour saturation and contrast in bright areas. The new Meylan, Alleyson,Süsstrunk method used in Lumincor avoids both of these defects and reproduces the colour of the original with greater fidelity. For the older methods see:
