Two-dimensional dispersion entropy: An information-theoretic method for irregularity analysis of images

作者：

Highlights：

• The two-dimensional dispersion entropy (DispEn2D) is herein introduced.

• DispEn2D allows to analyze irregularity of images.

• DispEn2D performance is analyzed on different datasets.

• DispEn2D shows better results than other entropy-based irregularity measures.

• DispEn2D shows promising results for texture analysis.
