Statistical independence is one of the most desirable properties of a coordinate system for representing and modeling images. In this paper, we propose an algorithm to rapidly construct a coordinate system "closest" to the statistically independent one from a dictionary of bases such as the wavelet packets and local Fourier bases. The criterion is to minimize the sum of the coordinate-wise differential entropy and is quite different from the Joint Best Basis (JBB) of Wickerhauser.
