We analyze whether Independant Component Analysis (ICA) is an appropriate tool for estimating spatial information in spatio-chromatic mosaiced color images.

ABSTRACT. We present a new algorithm that performs demosaicing and super-resolution jointly from a set of raw images sampled with a color filter array.
