Regression Model for Speckled Data with Extremely Variability
A. D. C. Nascimento, J. M. Vasconcelos, R. J. Cintra +1
Synthetic aperture radar (SAR) is an efficient and widely used remote sensing tool. However, data extracted from SAR images are contaminated with speckle, which precludes the appli…
Detecting Changes in Fully Polarimetric SAR Imagery with Statistical Information Theory
Abraão D. C. Nascimento, Alejandro C. Frery, Renato J. Cintra
Images obtained from coherent illumination processes are contaminated with speckle. A prominent example of such imagery systems is the polarimetric synthetic aperture radar (PolSAR…
A new extended Cardioid model: an application to wind data
Fernanda V. Paula, Abraão D. C. Nascimento, Getúlio J. A. Amaral
The Cardioid distribution is a relevant model for circular data. However, this model is not suitable for scenarios were there is asymmetry or multimodality. In order to overcome th…
Closed-form mathematical expressions for the exponentiated Cauchy-Rayleigh distribution
Thiago VedoVatto, Abraao David Costa do Nascimento
The Cauchy-Rayleigh (CR) distribution has been successfully used to describe asymmetric and heavy-tail events from radar imagery. Employing such model to describe lifetime data may…
Bias Correction and Modified Profile Likelihood under the Wishart Complex Distribution
Abraão D. C. Nascimento, Alejandro C. Frery, Renato J. Cintra
This paper proposes improved methods for the maximum likelihood (ML) estimation of the equivalent number of looks . This parameter has a meaningful interpretation in the context…
Information Theory and Image Understanding: An Application to Polarimetric SAR Imagery
A. C. Frery, A. D. C. Nascimento, R. J. Cintra
This work presents a comprehensive examination of the use of information theory for understanding Polarimetric Synthetic Aperture Radar (PolSAR) images by means of contrast measure…
