annie is a C++ API (library) for neural network training and execution. It can be linked to both Windows and Linux applications. Support for multi-layer perceptron networks, radial-basis networks, and Hopfield Networks is present. It can also be interfaced with Matlab's Neural Network toolbox.
libperceptronnetwork is a library that models a multilayer feedforward perceptron network, a well-known and understood type of neural network. It can be used for a large number of recognition and categorization tasks. Besides providing the standard propagation and backpropagation algorithms, the library also provides variations to the backpropagation algorithm, such as optional weight-decay, momentum-term and optimal-tolerance methods. It comes with a handy programmers reference manual and two examples.
libGMUVision is framework for realtime computer vision applications that is designed to allow easier access to Firewire IIDC digital video cameras. It provides a set of C++ bindings for libdc1394 and Qt widgets for building graphical applications that process video streams in real time. A small sample application (Koriander Lite, based on the Coriander project) is included.
myBeasties is a highly flexible evolutionary programming module. It is designed to be extendable and customisable for maximum use by the Perl developer. Many species of genotypes can be evolved, and these can be used to build phenotypes of any size or complexity. These can be as simple as a list or as large as a whole class of objects.
