- AlgART are free software Java libraries, supporting generalized smart arrays and matrices with elements of any types (1 bit, 8/16/32/64-bit integers, 32/64-bit floating point values and any other Java types), including a wide set of of 2D-, 3D- and multidimensional image processing and other algorithms, working with arrays and matrices.
- The libraries use 63-bit addressing of array elements (all indexes and length are represented by 64-bit long type). So, it's theoretically possible to create and process arrays and matrices containing up to 2^63-1 (~10^19) elements of any primitive or non-primitive types, if OS and hardware can provide necessary amount of memory or disk space.
- Memory model concept allows storing AlgART arrays in different schemes, from simple Java arrays to mapped disk files; all necessary data transfers are performed automatically while every access to an element or a block of elements.
- Most of algorithms are based on wide usage of lazy evaluations. Typical operations, like elementwise summing or geometrical matrix transformations, are implemented via lazy views of the source array or matrix.
- For example, you can take a multidimensional matrix, rotate it (or perform any other affine or projective transform), and then extract a submatrix from the result. All these operations will be performed virtually (not requiring time), and actual calculations will be performed only at the moment of accessing elements, usually while copying the resulting matrix to a newly created one. Moreover, in many cases the libraries will "understand" itself, that the user wants to perform rotation or another transform, and will split the matrix into suitable rectangular blocks (fitting in RAM) and choose the best algorithm for this task at the moment of copying operation.
- The libraries contain a wide set of image processing algorithms over matrices: linear filtering, mathematical morphology, rank operations, spectral transformation (FFT), etc.
- There is also skeletonization and measuring of binary images.
- BRL-CAD includes an interactive geometry editor, parallel ray-tracing support for rendering and geometric analysis, path-tracing for realistic image synthesis, network distributed framebuffer support, image-processing and signal-processing tools.
- Castle Game Engine
- Castle Game Engine is a cross-platform 3D and 2D game engine for Object Pascal (FPC and Lazarus). - It supports many formats for game assets, including X3D, VRML, Collada, Spine JSON, MD3 and others. - Many graphic effects are possible, including bump mapping, shadows, shaders, mirrors, screen effects. - Animation, collision detection, 3D sound and more features are available. - An extensible system of 3D objects can be used, with out-of-the-box levels, items, intelligent creatures and more. - The engine is portable -- for desktop, mobile, web plugin. The engine is also used to develop view3dscene - a full-featured X3D / VRML browser and a viewer for many other 3D and 2D game formats.
- Chafa is a command-line utility that converts all kinds of images, including animated GIFs, into ANSI/Unicode character output that can be displayed in a terminal. It is highly configurable, with support for alpha transparency and multiple color modes and color spaces, combining selectable ranges of Unicode characters to produce the desired output. The core functionality is provided by a C library with a public, well-documented API.
- Multiplatform raster graphical editor enabling simultaneous drawing between users. Project including several sub projects as server, painting framework, network library, desktop application and protocol design and documentation.
- DataMelt (DMelt) is an environment for numeric computation, statistical analysis, data mining, and graphical data visualization on the Java platform. This Java multiplatform program is integrated with a number of scripting languages: Jython (Python), Groovy, JRuby, BeanShell. DMelt can be used to plot functions and data in 2D and 3D, perform statistical tests, data mining, numeric computations, function minimization, linear algebra, solving systems of linear and differential equations. Linear, non-linear and symbolic regression are also available. Neural networks and various data-manipulation methods are integrated using powerful Java API. Elements of symbolic computations using Octave/Matlab scripting are supported.
- FLIF is a novel lossless image format which outperforms existing image formats in terms of compression ratio. It works well on any kind of image (photographic, line art, computer graphics, etc.) and also supports animations. FLIF images (or animations) can be progressively decoded, which makes the format potentially very suitable for responsive web design. This is the reference implementation of FLIF, which includes a command-line tool (flif) to convert between FLIF and PNG/PNM/PAM, a decoding library (libflif_dec), an encoding library (libflif_enc), some scripts (gif2flif, apng2flif, raw2flif, ...), and a simple image/animation viewer (viewflif).
- Farbfeld Utilities
- A simple format for dealing with pictures, which is 16-bits per channel RGBA. These program can convert to/from other format and make various effects with them; some also make up new pictures.
- FractGen is a simple Qt-based fractal generator program for Mandelbrot fractals. The image size is only limited by virtual memory. It is possible to zoom into images. Image parameters can be saved in XML files and loaded from XML files. Calculated images can be exported as PNG files. The intention of this program is to generate graphics to be post-processed by other image tools, e.g. in order to generate nice screen backgrounds or book covers.
- G'MIC is a full-featured free software framework for image processing, distributed under the CeCILL license. It provides several different user interfaces to convert / manipulate / filter / visualize generic image datasets, ranging from 1d scalar signals to 3d+t sequences of multi-spectral volumetric images, thus including 2d color images.
- A command-line interface gmic, to use the G'MIC image processing features from a shell. In this setting, G'MIC may be seen as a friendly companion to the ImageMagick or GraphicsMagick software suites.
- A small, portable, thread-safe and multi-threaded, C++ image processing library libgmic, to be linked to third-party applications. Its simple API allows programmers to add all G'MIC features in their own software without much efforts (a C API is available as well).
- A plug-in gmic_gimp, to bring G'MIC capabilities to the image retouching software GIMP. More than 450 filters are already available, sorted by category (Artistic, Black & white, Colors, Contours, Deformations, Degradations, Details, Film emulation, Frames, Layers, Light & shadows, Patterns, Rendering, Repair, Sequences, etc.).
- A web service G'MIC Online, to allow users applying image processing algorithms on their images, directly from a web browser.
- A Qt-based interface ZArt, for real-time processing of video streaming coming from webcams or video files.
