DROID (Digital Record Object Identification) is a
software tool to perform automated batch
identification of file formats. It is designed to
meet the fundamental requirement of any digital
repository to be able to identify the precise
format of all stored digital objects, and to link
that identification to a central registry of
technical information about that format and its
dependencies. It uses internal and external
signatures to identify and report the specific
file format versions of digital files. These
signatures are stored in an XML signature file,
generated from information recorded in the PRONOM
technical registry. New and updated signatures are
regularly added to PRONOM, and DROID can be
configured to automatically download updated
signature files from the PRONOM Web site via Web
services.

Gerbil consists of an interactive visualization tool targeted at multispectral and hyperspectral image data, and a toolbox of common algorithms, e.g. for segmentation. Multispectral imaging has been gaining popularity and has been gradually applied to many fields besides remote sensing. However, due to the high dimensionality of the data, both human observers and computers have difficulty interpreting this wealth of information. Gerbil facilitates the visualization of the relationship between spectral and topological information in a novel fashion. It puts emphasis on the spectral gradient, which is shown to provide enhanced information for many reflectance analysis tasks. It also includes a rich toolbox for evaluation of image segmentation and other algorithms in the multispectral domain. The parallel coordinates visualization technique is combined with hashing for a highly interactive visual connection between spectral distribution, spectral gradient, and topology.

Pymorph is a collection of pure Python implementations of many image morphology functions. It Includes basic operations such as erode, dilate, open, tophat opening, and watershed.

The STX ExecPipe library provides a convenient C++ interface to execute child programs connected via pipes. It is a front-end to the system calls fork(), pipe(), select(), and execv() and hides all the complexity of these low-level functions. It allows a program to build a sequence of connected children programs with the input and output of the pipe sequence redirected to a file, string, or file descriptor. The library also allows custom asynchronous data processing classes to be inserted into the pipe or placed at the source or sink of the sequence.

MibianLib is an options pricing library offering the ability to calculate the price, the implied volatility, the Greeks or the put-call parity of an option using the Garman-Kohlhagen, Black-Scholes, and Merton models.

TreeTagger for Java (TT4J) is a Java wrapper around the popular TreeTagger package by Helmut Schmid, a language independent part-of-speech tagger and lemmatizer. It was written with a focus on platform-independence and easy integration into applications.

dbus-cxx is a C++ wrapper for dbus that supports introspection and includes a proxy/adapter generator (dbus-cxx-xml2cpp). What differentiates dbus-cxx from other C++ wrappers is that dbus-cxx relies heavily on sigc++ and explicitly exposes the wrapped D-Bus C API.

txtorcon is a Twisted-based asynchronous Tor control protocol implementation.

Twisted is an event-driven networking engine written in Python, and Tor is an onion-routing
network designed to improve people’s privacy and security on the Internet.


It includes unit-tests with 96%+ coverage,
multiple examples, and documentation.

There are abstractions to track Tor configuration and
state (circuits,
streams),
launch private
instances,
support Hidden Service, and more.
