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…

Comparing Samples from the Distribution using a Geodesic Distance

Alejandro C. Frery, Juliana Gambini

The distribution is widely used for monopolarized SAR image modeling because it can characterize regions with different degree of texture accurately. It is indexed…

Parameter Estimation for the Single-Look Distribution

Débora Chan, Andrea Rey, Juliana Gambini +1

The statistical properties of Synthetic Aperture Radar (SAR) image texture reveals useful target characteristics. It is well-known that these images are affected by speckle, and pr…

The Geodesic Distance between Models and its Application to Region Discrimination

José Naranjo-Torres, Juliana Gambini, Alejandro C. Frery

The distribution is able to characterize different regions in monopolarized SAR imagery. It is indexed by three parameters: the number of looks (which can be esti…

Fast Cosine Transform to increase speed-up and efficiency of Karhunen-Loeve Transform for lossy image compression

Mario Mastriani, Juliana Gambini

In this work, we present a comparison between two techniques of image compression. In the first case, the image is divided in blocks which are collected according to zig-zag scan.…

Parameter Estimation in SAR Imagery using Stochastic Distances and Asymmetric Kernels

Juliana Gambini, Julia Cassetti, María Magdalena Lucini +1

In this paper we analyze several strategies for the estimation of the roughness parameter of the distribution. It has been shown that this distribution is able to…

Polarimetric SAR Image Segmentation with B-Splines and a New Statistical Model

Alejandro C. Frery, Julio Jacobo-Berlles, Juliana Gambini +1

We present an approach for polarimetric Synthetic Aperture Radar (SAR) image region boundary detection based on the use of B-Spline active contours and a new model for polarimetric…
