Marvin is an extensible image processing framework for Java. It provides features to manipulate images, to manipulate captured video frames, and to process images with multi-threading. Its features can be extended via plug-ins. Plug-ins can be integrated with the graphical user interface, and their plug-in performance can be analyzed. Every image processing algorithm is developed as a plug-in that can be plugged into the MarvinEditor, an image manipulation program that uses plug-ins developed using Marvin, or into third-party applications. Currently there are 55 plug-ins available.
Fix8 is a modern open source C++ FIX framework featuring complete schema driven customisation, high performance, and fast application development. The system is comprised of a compiler for generating C++ message and field encoders, decoders, and instantiation tables, a runtime library to support the generated code and framework, and a set of complete client/server test applications. For the same message, Fix8 encodes 3.2 times faster and decodes 2.3 times faster than Quickfix, an average of 2.7 times. In other words, it reduces encode latency by 69% and reduces decode latency by 56%.
Dr. Geo is an interactive geometry program that is distributed as a universal portable application. It allows one to create a geometric sketch and manipulate it according to its constraints. It is usable at home or at school, in primary or secondary education. It is simple and effective with extended features including scripting and programming.
GNU libmicrohttpd is a small C library for embedding HTTP server functionality into other applications. It is reentrant, fast, supports HTTP 1.1, and permits listening on multiple ports. The API is simple and still powerful enough to allow programmers to use the entire HTTP feature set. SSL/TLS support is available as an option.
c++-gtk-utils is a lightweight library containing a number of classes and functions for programming GTK+ programs using C++ in POSIX environments where the user does not want to use a full-on wrapper such as gtkmm or wxWidgets. It provides classes for managing the lifetimes of GTK+ widgets and windows that will make GTK+ exception safe, functions to make single instance programs where restarting will bring up the existing instance, smart pointer classes for memory management, thread-safe signal/slot classes with automatic disconnection, classes for using std iostreams with files opened with Unix file descriptors, functions for connecting a callback object and a Unix file descriptor to the main loop with provision for automatic disconnection, classes and functions for inter-thread communication, some convenience pthread wrapper classes., a class encapsulating anonymous Unix pipes, a class to reassemble UTF-8 sent over pipes and sockets, and classes for printing Postscript files and plain text using the GTK+ print system.
DDMSence (pronounced "dee-dee-em-Essence") is the only Java library that fully supports the DoD Discovery Metadata Specification (DDMS). It provides a complete implementation of the DDMS specification using any DDMS version between 2.0 and 5.0. Validation is performed according to both the schema and the specification, and custom validation rules can be defined with ISO Schematron.
