Convex processing is a quick and efficient library to implement algorithms based on convex analysis. Some specific fields are addressed, such as general image processing and tomography. The graphical interface allows users to play with some reconstruction algorithms in tomography and denoising. For developers, the API is simple, several examples of use are provided, and all important parts are covered by unit tests. This software is intended to help people play, understand, and improve those algorithms.
iMorph is cross platform 3D image analysis software. It permits the morphological characterization of porous media, and more precisely cellular materials. The first step of the analysis is a macroscopical characterization of the different phases. It allows porosity, tortuosity, and specific surface measurement. The anisotropy is also quantified at the sample scale. In a second step, the software gives a morphological study at the pore scale. Automatic methods for cell extraction give access to shape analysis, classification, and orientation. Moreover, it permits a local voxel classification in order to identify local shape such as shell, plates, and rods. Finally, the software gives a topological description by generating the graphs of both the solid and fluid phase. The human interface is intuitive and can be used by a non-expert of image processing. 3D visualization uses OpenGL libraries and allows interaction with segmented objects. An XML samples database is used to store results belonging to a region of interest in the media.
Fiji is an image processing package. It can be described as a distribution of ImageJ together with Java, Java 3D, and a lot of plugins organized into a coherent menu structure. Fiji compares to ImageJ as Ubuntu compares to Linux. The main focus of Fiji is to assist research in life sciences. For users, Fiji is easy to install and has an automatic update function, bundles a lot of plugins and offers comprehensive documentation. Developers may access the source code of all internals, libraries, and plugins, which eases the development and scripting of plugins.
Animmerger stitches 2D images together into either a static image or an animation, while attempting to preserve a global frame of reference (static background). That is, for a movie that follows an actor around (and the background scrolls to follow them), it creates a movie that has a fixed background, and the camera moves around in the scene. The most obvious application of animmerger is in automatic map stitching for 2D video games, but there are many general purposes for which the program can be used. Its color quantization and dithering algorithm set is particularly advanced.
