Tautomaton is a C++11 -template library for deterministic (DFA) and non-deterministic finite automata (NFA). It supports regular expressions and efficient input matching of multiple regexps simultaneously. The library comes with a somewhat grep-like command-line tool for showcasing these features.
The epler project's main intention is to provide a library with bindings to C++, and eventually C, Python and Fortran for manipulating, analyzing and visualizing large datasets. Building frontends on top of this isolated library is also planned.
It's a flexible software bundle and framework for face recognition, which enables users to log into computer automatically, perform face detection, recognition and tracking, and perform experiments. Other applications can be built on top of it.
