FFTW++ is a C++ header class for the FFTW Fast Fourier Transform library that automates memory allocation, alignment, planning, and wisdom. In 2D and 3D, implicit dealiasing of convolutions substantially reduces memory usage and computation time. Wrappers for C, Python, and Fortran are included.
Gerbil consists of an interactive visualization tool targeted at multispectral and hyperspectral image data, and a toolbox of common algorithms, e.g. for segmentation. Multispectral imaging has been gaining popularity and has been gradually applied to many fields besides remote sensing. However, due to the high dimensionality of the data, both human observers and computers have difficulty interpreting this wealth of information. Gerbil facilitates the visualization of the relationship between spectral and topological information in a novel fashion. It puts emphasis on the spectral gradient, which is shown to provide enhanced information for many reflectance analysis tasks. It also includes a rich toolbox for evaluation of image segmentation and other algorithms in the multispectral domain. The parallel coordinates visualization technique is combined with hashing for a highly interactive visual connection between spectral distribution, spectral gradient, and topology.
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.
animbar lets you easily create your own animation on paper and transparancy. From a set of input images, two output images are computed that are printed, one on paper and one on transparency. By moving the transparency over the paper, a fascinating animation effect is created. This animation technique has been known for hundreds of years under names such as picket fence animation, barrier grid animation, and others.
Into is a cross-platform machine intelligence application framework written in C++. Into provides a different, fast way to build high-performance applications for image analysis, machine vision, pattern recognition, and artificial intelligence. It features a layered API and more than 20 fully interoperable plug-in modules for accessing image and data sources, powerful feature extractors, classifiers, neural networks, and much more. It also provides Ydin, an innovative execution engine that makes it easy to create dynamic programs that automatically run in parallel, enabling you to create more with less hassle, less code, and less time. Into uses Qt to let you create beautiful user interfaces for your applications with ease.
The Common Pipeline Library provides a highly robust set of functions for manipulating signals and images. It is primarily intended for the building of VLT instrument pipelines, but is also useful for generic data handling. It includes a number of useful low-level data types, medium-level data access methods, standard implementations of commonly-used signal processing and data reduction tasks, and dynamic loading of "recipes" for data processing.
