Knotter is a highly configurable interlace designer. Interlace patterns are a kind of design historically used as a decorations in many places and by different cultures (some examples are Celtic knotworks and Islamic interlaces). Knotter aims to allow its user to design such patterns in an intuitive way and to provide easy ways to integrate the result into external general-purpose graphic software. For this purpose, designs created within Knotter can be saved in a custom human-readable format and exported as Scalable Vector Graphics and in a wide number of raster image formats.
Hypercube is a graph visualization tool for drawing DOT (graphviz), GML, GraphML, GXL and simple text-based graph representations as SVG and EPS images. It comes with a Qt-based GUI application and a Qt-independent commandline tool. Hypercube uses a simulated annealing algorithm to lay out the graph, which can be easily parameterized to achieve the desired look.
Ostinato is a network packet and traffic generator and analyzer with a friendly GUI. It aims to be "Wireshark in Reverse" and thus become complementary to Wireshark. It features custom packet crafting with editing of any field for several protocols: Ethernet, 802.3, LLC SNAP, VLAN (with Q-in-Q), ARP, IPv4, IPv6, IP-in-IP a.k.a IP Tunneling, TCP, UDP, ICMPv4, ICMPv6, IGMP, MLD, HTTP, SIP, RTSP, NNTP, etc. It is useful for both functional and performance testing.
HeldenViewer makes it possible to search for, download, and view Youtube videos in a very easy to use fashion. An important feature is the concept of adding authors as favorites, in order to be notified at the next start of HeldenViewer if the author has uploaded a new video. You will no longer be interrupted by any commercials. Much like the Youtube platform, you can watch the videos while downloading and use your favorite videoplayer to do this. The only restriction is that the video player must be able to play .flv files, e.g. VideoLanClient.
YAGF is a graphical frontend for the cuneiform and tesseract OCR tools. It lets you open already scanned image files or obtain new images via XSane (scanning results are automatically passed to YAGF). Once you have a scanned image you can prepare it for recognition, select particular image areas for recognition, set the recognition language and so on. Recognized text is displayed in an editor window where it can be spell-checked, corrected, saved to disk, or copied to clipboard. YAGF also provides some facilities for a multi-page recognition.
QPass is a password manager application. It enables you to store your confidential data encrypted. All entries are stored in a single-file database encrypted using the AES-256 algorithm. Each entry can contain a name, URL, username, password, and description. QPass can also generate random passwords based on mouse movements.
AstroAviBrowser is a small tool for astronomy imaging capture/processing. It allows you to open a video file, select the good frames, and save the new sequence in a new avi file using raw or lossless codecs. You may also de-bayer your frames and separate RGB plans. It's a kind of "AviRaw" for Linux.
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.
animbar lets you easily create your own animation on paper and transparancy. From a set of input images, two output images are computed that are printed, one on paper and one on transparency. By moving the transparency over the paper, a fascinating animation effect is created. This animation technique has been known for hundreds of years under names such as picket fence animation, barrier grid animation, and others.
