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…
On the Use of Lee's Protocol for Speckle-Reducing Techniques
Elsa E. Moschetti, M. Gabriela Palacio, Mery Picco +2
This paper presents two new MAP (Maximum a Posteriori) filters for speckle noise reduction and a Monte Carlo procedure for the assessment of their performance. In order to quantita…
Assessment of SAR Image Filtering using Adaptive Stack Filters
Maria E. Buemi, Marta Mejail, Julio Jacobo +2
Stack filters are a special case of non-linear filters. They have a good performance for filtering images with different types of noise while preserving edges and details. A stack…
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…
Deconvolution of vibroacoustic images using a simulation model based on a three dimensional point spread function
Talita Perciano, Matthew Urban, Nelson D. A. Mascarenhas +3
Vibro-acoustography (VA) is a medical imaging method based on the difference-frequency generation produced by the mixture of two focused ultrasound beams. VA has been applied to di…
Stochastic particle packing with specified granulometry and porosity
A. C. Frery, L. Rivarola-Duarte, V. Carrilho Leão Ramos +2
This work presents a technique for particle size generation and placement in arbitrary closed domains. Its main application is the simulation of granular media described by disks.…
