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.
The Helix DNA Producer is a multi-format media-encoding engine for creating streaming broadcasts, on-demand streaming content, and downloadable audio video files. It supports RealAudio, RealVideo, and Ogg Vorbis, and includes many input and output filters, variable bitrate encoding support, option for two-pass encoding, audio gain control, and Firewire support.
The GNU Compact Disc Input and Control library encapsulates CD-ROM reading and control for applications wishing to be oblivious to the OS- and device-dependent properties of a CD-ROM. It provides an API for access to SCSI-MMC (multimedia commands) and support for CD image types like BIN/CUE, cdrdao's TOC, and Nero's NRG, which gives applications using the library the ability to read disc images as though they were CDs. ISO-9660 filesystem support is included, as are utility programs for displaying CD and CD-ROM drive information, reading the blocks of a CD, and extracting files from an ISO-9660 filesytem image. cdparanoia is also included.
OpenVIP is a flexible video-processing tool for Unix and Windows. It consists of two parts: the OpenVIP core, which is written in C/C++, and a Python GUI editor based on the timeline concept. The library can be used by other multimedia applications and is easily extensible with custom plugins (I/O formats, filters, transitions or more general modules).
VXL is a set of portable C++ libraries designed for computer vision research and implementation. Numerics, imaging, and geometry are provided by stand-alone core libraries, with easy to use APIs and sophisticated processing algorithms. Other libraries provide stereo, video, structure from motion, probability modeling, GUI design, classification, robust estimation, feature tracking, topology, 3d imaging, and much more. It is written and used by an international team from academia and industry.
