Ultrasound imaging suffers from severe artifacts caused by speckle noise. The paper
introduces an algorithm for speckle noise reduction in breast cancer ultrasound images …

This paper presents a new image abstraction approach, aiming to improve typical image
related pattern recognition tasks such as segmentation, tracking, and classification. The …

Synthetic aperture radar (SAR) is an active imaging system that can achieve high
resolutions both in range and azimuth. Speckle noise is one of the most critical disturbances …

We address the issue of adapting optical images-based edge detection techniques for use
in Polarimetric Synthetic Aperture Radar (PolSAR) imagery. We modify the gravitational …

In a context of markets globalization, early, reliable and timely estimations of crop yields at
regional to global scale are clearly needed for managing large agricultural lands …

In this work, a new nonlocal means filter for single-look speckled data using the Shannon
and Renyi entropies is proposed. The measure of similarity between a central window and …

This article introduces a continuous probability distribution as an approximation to the
distribution for amplitude synthetic aperture radar (SAR) imagery modeling. Called …

Abstract Synthetic Aperture Sonar (SAS) is a sensor that was designed for hydrographic
survey of the seabed. It detects small targets, enabling high geometric resolution images …

The paper addresses structural decomposition of images by using a family of non-linear and
non-convex objective functions. These functions rely on ℓ p quasi-norm estimation costs in a …

New deblocking artifact, or blocking artifact reduction, algorithms based on nonlinear
adaptive soft-threshold anisotropic filter in wavelet are proposed. Our deblocking algorithm …
