The Chemistry Development Kit (CDK) is a library of Java classes for chemo-, bioinformatics, computational chemistry, and chemometrics. It provides important algorithms like substructure search, SMILES, Gasteiger charges, QSAR descriptor calculation, 3D structure generation, 2D layout and rendering, many IO formats, atom typing, and more.
CVL is a library for image and data processing using graphics processing units (GPUs). It is suitable as a base for GPGPU applications. Cvtool is a general-purpose computer vision tool that is based on the CVL library. It works as a filter by reading streams of data from standard input and writing manipulated data and/or analysis results to standard output. Complex analysis tasks can easily be realized in scripts. Many image and video manipulation and analysis functions are included, as well as some advanced computer vision techniques.
unicap is a library to access different kinds of capture devices. Device drivers are loaded with a plugin system so that new drivers can be easily added. Currently, it has support for video-4-linux, video-4-linux-2, IIDC cameras, and video-to-firewire converters, and provides GTK widgets for live video display and access to device properties.
Eckbox is van Eck Phreaking tool that interprets a radio signal emanating from a computer's monitor to recreate the image (in black and white) that is displayed on it. It could be used as a valuable security tool for testing otherwise secure computers or for developing hardware and software to counter this type of remote shoulder-surfing. It is not intended to be used for illegal purposes, and includes information on the hardware required.
