QuantLib is a cross-platform, quantitative finance C++ library for modeling, pricing, trading, and risk management in real-life. It is also wrapped as Python/Ruby/Scheme modules. Extensions for Excel, R, and Mathematica are available. Other such extensions are under consideration. QuantLib offers tools that are useful both for practical implementation and for advanced modeling. It features market conventions, yield curve models, solvers, PDEs, Monte Carlo (low-discrepancy included), exotic options, VAR, and so on.
Autopano-SIFT is a helper program for panorama image generation. It automatically generates control point information for a number of image files for use with the hugin panorama generation software. To do this, it utilizes the SIFT (Scale-Invariant Feature Transform) algorithm, a sophisticated image feature matching algorithm.
Visual Paradigm for UML is a Unified Modeling Language (UML) design tool that supports all UML diagrams, SysML diagrams, and entity relationship diagrams. Visual Paradigm for UML provides extensive use case modeling features, including full function UML use case diagram, flow of events editor, use case/actor grid, and activity diagram generation. Visual Paradigm for UML produces system documentation in PDF, HTML, and MS Word formats. A developer can design system documentation with the template designer. A system analyst can estimate the consequences of changes with impact analysis diagrams, such as matrix and analysis diagram. Visual Paradigm for UML generates Java code.
SDE for Eclipse is a UML modeling environment tightly integrated with Eclipse IDE. It lets you draw all types of UML diagrams (use case diagrams, class diagrams, component diagrams, etc.) in Eclipse, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams. It features the latest UML notation support, a Rational Rose importer, an XMI importer, Microsoft Visio integration, HTML/PDF documentation generators, and plug-in and template support.
The scale-invariant feature transform is an algorithm to identify and locate interesting points within an image. For all such points, a descriptive signature is extracted. The signatures can be stored and matched among multiple images, allowing for a large number of interesting applications, such as aligning overlapping images and identifying objects or motion within image sequences. libsift is used by the autopano-sift program to create panorama images.
Waveblend is a focus enhancing tool. It implements an image fusion algorithm to combine many images to one, using the images most in focus at each point; the resulting image is in focus everywhere. It uses the complex dual-tree two dimensional discrete wavelet transform algorithm, with a number of pre- and post-processing steps.
iBookshelf is an application for cataloging your book collection and designing bookshelves based on this data. It supports ISBN entry using a CueCat, a standard barcode scanner, or manual entry. Book data is automatically fetched from Amazon Web services. Manual book entry is possible for non-catalogued books. Bookshelf design is done graphically with the Cairo drawing library, and is based on the most efficient book order.
