Retinex Colour

A scene is photographed twice with the same camera and two colour filters as shown in the figure.  Green and red filters are shown but others can be used.  The filters need only be 'short wavelength' and 'long wavelength' respectively.  The black-and-white slides (shown below the camera figures) contain different spectral information.


Retinex Image Taking (6470 bytes)


The colour reconstruction requires two projectors with the images aligned and one colour filter;- the red (long wavelength) one.
