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…
Contrast Measures based on the Complex Correlation Coefficient for PolSAR Imagery
Alejandro C. Frery, Renato J. Cintra, Abraão D. C. Nascimento
We derive contrast measures which involve the number of looks and the complex correlation coefficient between polarization channels in PolSAR imagery. Using asymptotic results whic…
