Fast computation of entropies and mutual information for multispectral images
This paper describes the fast computation, and some applications, of entropies and mutual information for color and multispectral images. It is based on the compact coding and fast processing of multidimensional histograms for digital images.
متن کاملShannon Mutual Information Applied to Genetic Systems
Shannon information has, in the past, been applied to quantify the genetic diversity of many natural populations. Here, we apply the Shannon concept to consecutive generations of alleles as they evolve over time. We suppose a genetic system analogous to the discrete noisy channel of Shannon, where the signal emitted by the input (mother population) is a number of alleles that will form the next...
متن کاملShannon Meets Carnot: Mutual Information Via Thermodynamics
In this contribution, the Gaussian channel is represented as an equivalent thermal system allowing to express its input-output mutual information in terms of thermodynamic quantities. This thermodynamic description of the mutual information is based upon a generalization of the 2 thermodynamic law and provides an alternative proof to the Guo-Shamai-Verdú theorem, giving an intriguing connection...
متن کاملInformation-theoretic computation complexity
This paper attempts to describe, in nontechnical language, some of the concepts and methods of one school of thought regarding computational complexity. It applies the viewpoint of information theory to computers. This will first lead us to a definition of the degree of randomness of individual binary strings, and then to an informationtheoretic version of Giidel’s theorem on the limitations of...
متن کاملShannon Entropy and Mutual Information for Multivariate SkewElliptical Distributions
The entropy and mutual information index are important concepts developed by Shannon in the context of information theory. They have been widely studied in the case of the multivariate normal distribution. We first extend these tools to the full symmetric class of multivariate elliptical distributions and then to the more flexible families of multivariate skew-elliptical distributions. We study...
