Abstract :
In this document we disclose a technique integrating both a color interpolation method and an antialiasing method in a single step. This solution permits a reduction of memory requirement. In fact no extra memory lines are required to perform the false colors removal. This technique drastically reduces false colors and zipper effect by exploiting at the same time both spatial and spectral correlations.
