Statistical Properties of the Entropy from Ordinal Patterns
Eduarda T. C. Chagas, Alejandro. C. Frery, Juliana Gambini +3
The ultimate purpose of the statistical analysis of ordinal patterns is to characterize the distribution of the features they induce. In particular, knowing the joint distribution…
Speckle Reduction in Polarimetric SAR Imagery with Stochastic Distances and Nonlocal Means
Leonardo Torres, Sidnei J. S. Sant'Anna, Corina C. Freitas +1
This paper presents a technique for reducing speckle in Polarimetric Synthetic Aperture Radar (PolSAR) imagery using Nonlocal Means and a statistical test based on stochastic diver…
Polarimetric SAR Image Smoothing with Stochastic Distances
Leonardo Torres, Antonio C. Medeiros, Alejandro C. Frery
Polarimetric Synthetic Aperture Radar (PolSAR) images are establishing as an important source of information in remote sensing applications. The most complete format this type of i…
Generalized Statistical Complexity of SAR Imagery
Eliana S. de Almeida, Antonio Carlos de Medeiros, Osvaldo A. Rosso +1
A new generalized Statistical Complexity Measure (SCM) was proposed by Rosso et al in 2010. It is a functional that captures the notions of order/disorder and of distance to an equ…
Speckle Reduction using Stochastic Distances
Leonardo Torres, Tamer Cavalcante, Alejandro C. Frery
This paper presents a new approach for filter design based on stochastic distances and tests between distributions. A window is defined around each pixel, samples are compared and…
