Scene dependence of the non-gaussian scaling properties of natural images
A. Nevado, A. Turiel, N. Parga
We report results on the scaling properties of changes in contrast of natural images in different visual environments. This study confirms the existence, in a vast class of images,…
The multi-fractal structure of contrast changes in natural images: from sharp edges to textures
A. Turiel, N. Parga
We present a formalism that leads very naturally to a hierarchical description of the different contrast structures in images, providing precise definitions of sharp edges and othe…
The self-similarity properties of natural images resemble those of turbulent flows
A. Turiel, G. Mato, N. Parga +1
We show that the statistics of an edge type variable in natural images exhibits self-similarity properties which resemble those of local energy dissipation in turbulent flows. Our…
Numerical simulation of a binary communication channel: Comparison between a replica calculation and an exact solution
D. R. C. Dominguez, M. Maravall, A. Turiel +2
The mutual information of a single-layer perceptron with Gaussian inputs and deterministic binary outputs is studied by numerical simulations. The relevant parameters of th…
