WebbAfter normalization, we calculate the entropy: H = − ∫ 0 1 p ( x) log ( p ( x)) d x ∼ − ∑ i p i log ( p i) ⋅ 1 N. As N → ∞ this gives an entropy which is solely related to the distribution shape and does not depend on N. For small N, the difference will depend on how good the Riemann sum approximates the integrals for given N.

The main conclusion of this study is that the encoding of coherent secondary flow structures can be achieved by an optimal number of binary digits (or bits) corresponding to an optimal wavelet scale.

WebbL' entropie de Shannon, due à Claude Shannon, est une fonction mathématique qui, intuitivement, correspond à la quantité d' information contenue ou délivrée par une source d'information. Cette source peut être un texte écrit dans une langue donnée, un signal électrique ou encore un fichier informatique quelconque (collection d'octets). WebbFormally, entropy is defined as follows: If X X is a discrete random variable with distribution P (X = xi) = pi P ( X = x i) = p i, then the entropy of X X is H (X) = −∑ ipilogpi. H ( X) = − ∑ i p i log p i.
