On optimal wavelet bases for the realization of microcanonical cascade processes
Oriol Pont, Jose M. D. Delgado, Antonio Turiel +1
Multiplicative cascades are often used to represent the structure of multiscaling variables in many physical systems, specially turbulent flows. In processes of this kind, these va…
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…
Understanding multifractality: reconstructing images from edges
Antonio Turiel, Angela del Pozo
It has been recently proven that natural images exhibit scaling properties analogue to those of turbulent flows. These properties allow regarding each image as a multifractal objec…
