Non-local means (NLM) filter is one of the state-of-the-art denoising filters. It exploits the
presence of similar features in an image and averages those similar features to remove …

This work aims to improve the process of speckle noise reduction while preserving edges
and other relevant features through filter expansion from 2-D to 3-D. Despeckling is very …

The main goal of this work is a presentation of a new algorithm dedicated to cysts detection
in Optical Coherence Tomography (OCT) images. Considered in this paper OCT scans …

The ramp preserving 2D nonlinear complex-diffusion filter introduced by Gilboa et al.(2004)
was extended to 3D (Maduro et al., 2012). We propose a graphical processing unit …

Optical coherence tomography (OCT) is an important tool for analyzing small animal models
of ocular disease. As OCT image quality and downstream analysis are affected by speckle …

The diffusion tensor image (DTI) is clinically polluted by Rician noise, which can bring
serious impacts on tensor calculating, fiber tracking and other post-processing. To decrease …

In this paper we focus on the development and implementation of an implicit finite difference
method for solving a complex diffusion differential equation with applications to noise …
