Multiscale two-dimensional permutation entropy to analyze encrypted images

Chaos. 2023 Jan;33(1):013112. doi: 10.1063/5.0130538.

Abstract

Multiscale versions of weighted (and non-weighted) permutation entropy for two dimensions are considered in order to compare and analyze the results when different experiments are conducted. We propose the application of these measures to analyze encrypted images with different security levels and encryption methods.
