Phys. Rev. Lett. 73, 814–817 (1994)Statistics of natural images: Scaling in the woodsReceived 23 March 1994; published in the issue dated 8 August 1994 We study the statistics of an ensemble of images taken in the woods. Distributions of local quantities such as contrast are scale invariant and have nearly exponential tails. Power spectra exhibit scaling with a nontrivial exponent. These data limit the information content of natural images and point to the importance of gain-control strategies in visual processing. © 1994 The American Physical Society URL:
