G++ and VSIPL++ is a commercial software development environment and toolkit for developing high-performance signal and image-processing applications.

…Code Forge IDE is an Integrated Development Environment for Unix/Linux that provides full project management and a complete edit/compile/debug cycle support for over 30 programming languages. Its advanced project management features allow it to scale from simple to extremely large and mixed-language as well as multi-user projects. Total integration between the built-in advanced source editor, debugger, revision control and difference tools provide the programmer with unprecedented control over the development process. A CodeForge IDE license includes 12 months of technical support and software upgrades. This period may be extended by purchasing an additional 12 months of priority technical support…This is a commercial product.

The Open Web Application Security Project (OWASP) is dedicated to finding and fighting the causes of insecure software. Everything here is free and open source. The OWASP Foundation is a 501c3 not-for-profit charitable organization that ensures the ongoing availability and support for our work. Participation in OWASP is free and open to all.

Fast Artificial Neural Network Library is a free open source neural network library, which implements multilayer artificial neural networks in C with support for both fully connected and sparsely connected networks. Cross-platform execution in both fixed and floating point is supported. It includes a framework for easy handling of training data sets. It is easy to use, versatile, well documented, and fast. PHP, C++, .NET, Ada, Python, Delphi, Octave, Ruby, Pure Data and Mathematica bindings are available. A reference manual accompanies the library with examples and recommendations on how to use the library. A graphical user interface is also available for the library. Features include:

• Multilayer Artificial Neural Network Library in C.
• Back propagation training (RPROP, Quickprop, Batch and Incremental).
• Evolving topology training which dynamically builds and trains the ANN (Cascade2).
• Easy to use (create, train and run an ANN with just three function calls).
• Fast (up to 150 times faster execution than other libraries).
• Versatile (possible to adjust many parameters and features on-the-fly).
• Well documented (An easy to use reference manual, a 50+ page university report describing the implementation considerations etc. and an introduction article).
• Cross-platform (configure script for linux and unix, dll files for windows, project files for MSVC++ and Borland compilers are also reported to work).
• Several different activation functions implemented (including stepwise linear functions for that extra bit of speed).
• Easy to save and load entire ANNs.
• Several easy to use examples (simple train example and simple test example).
• Can use both floating point and fixed point numbers (actually both float, double and int are available).
• Cache optimized (for that extra bit of speed).
• Open source (licensed under LGPL).
• Framework for easy handling of training data sets.
• Graphical Interface.
• C++ Bindings.
• PERL Bindings.
• PHP Extension.
• Python Bindings.
• Delphi Bindings.
• .NET Bindings.
• Mathematica Extension.
• Octave Extension.
• Squeak Smalltalk bindings.
• Pure Data Bindings.
• RPM package.
• Debian package.

…The Lemur Toolkit is designed to facilitate research in language modeling and information retrieval, where IR is broadly interpreted to include such technologies as ad hoc and distributed retrieval, cross-language IR, summarization, filtering, and classification. The toolkit supports indexing of large-scale text databases, the construction of simple language models for documents, queries, or sub collections, and the implementation of retrieval systems based on language models as well as a variety of other retrieval models. The system is written in the C and C++ languages, and is designed as a research system to run under Unix operating systems, although it can also run under Windows.

The toolkit is being developed as part of the Lemur Project, a collaboration between the Computer Science Department at the University of Massachusetts and the School of Computer Science at Carnegie Mellon University…

OGRE is an open source real time 3D rendering engine. OGRE is packed with features to make your development life easier, whether you’re making games, architectural visualization, simulations, or anything else which requires a top-notch 3D rendering solution.

FLTK (pronounced “fulltick”) is a cross-platform C++ GUI toolkit for UNIX®/Linux® (X11), Microsoft® Windows®, and MacOS® X. FLTK provides modern GUI functionality without the bloat and supports 3D graphics via OpenGL® and its built-in GLUT emulation. FLTK is designed to be small and modular enough to be statically linked, but works fine as a shared library. FLTK also includes an excellent UI builder called FLUID that can be used to create applications in minutes. FLTK is provided under the terms of the GNU Library Public License, Version 2 with exceptions that allow for static linking.

The Python Imaging Library (PIL) adds image processing capabilities to your Python interpreter. This library supports many file formats, and provides powerful image processing and graphics capabilities. Browse also other Phyton libraries.

CL-GD is a library for Common Lisp which provides an interface to the GD Graphics Library for the dynamic creation of images. It is based on UFFI and should thus be portable to all CL implementations supported by UFFI. A version which also works with CLISP is available from CLISP (in tgz). Also, beginning from version 0.5.0/0.5.1, CL-GD contains initial code to support CLISP and OpenMCL via CFFI. CL-GD comes with a BSD-style license so you can basically do with it whatever you want.
