GREYCstoration is an image regularization algorithm that processes an image by locally removing small variations of pixel intensities while preserving significant global image features, such as sharp edges and corners. The most direct application is denoising. By extension, it can also be used to inpaint or resize images. It is based on methods using nonlinear multi-valued diffusion PDEs (Partial Differential Equations) for image regularization. This kind of method generally outperforms basic image filtering techniques (such as convolution, median filtering, etc.) classically encountered in painting programs. Other image denoising plugins are available, but are not free, and the corresponding algorithms are kept secret.
V_Sim visualizes atomic structures such as crystals, grain boundaries, molecules, and so on It can work with files either in binary format or in plain text format. The rendering is done in pseudo-3D with colored spheres to represent the atoms. The user can interact through many functions to choose the view, the size of the atoms, their color, the background color, the type of fog, and more. Moreover, V_Sim allows you to export the view as images in GIF, PS, and other formats.
MyCGR implements the research of the thesis of Peggy Cénac regarding the use of CGR (Chaos Game Representation) to build a new family of tests for the structure of sequences. It can empirically check the level and power of the tests and apply them on DNA sequences. It can generalize the dinucleotide abundance profile to a CGR-based relative abundance profile and use this profile on DNA sequences to build taxonomy trees and to define CGR-trees.
Orfeo Toolbox (OTB) is a high resolution remote sensing image processing library. It contains a set of algorithmic components which allow the user to capitalize on methodological know how, and therefore use an incremental approach to profit from the results of methodological research. OTB is made of a set of basic elements (a C++ class API) and utilities (independent programs built upon the base API).
