I describe a statistical model for natural
photographic images, when decomposed in a multi-scale wavelet basis.
In particular, I examine both the marginal and pairwise joint histograms of
wavelet coefficients at adjacent spatial locations, orientations, and
spatial scales. Although the histograms are highly non-Gaussian, they
are nevertheless well described using fairly simple parameterized
density models.
