Engauge Digitizer is digitizing software that converts an image showing a graph or map into numbers. The image file can come from a scanner, digital camera, or screenshot. The numbers can be read on the screen, and written or copied to a spreadsheet. Highlights for beginners include an intuitive interface and extensive context-sensitive documentation. Highlights for experts include compensation for image distortion, cartesian and polar coordinates, linear and logarithmic coordinates, automatic scanning, graphical previews, and browser help.
CGAL, the Computational Geometry Algorithms Library, is a large C++ library of geometric data structures and algorithms such as Delaunay triangulations, mesh generation, Boolean operations on polygons, and various geometry processing algorithms. CGAL is used in various areas: computer graphics, scientific visualization, computer aided design and modeling, geographic information systems, molecular biology, medical imaging, robotics and motion planning, and numerical methods.
Madagascar is a software package for multidimensional data analysis and reproducible computational experiments. Its mission is to provide a convenient and powerful environment and a convenient technology transfer tool for researchers working with digital image and data processing in geophysics and related fields. Technology developed using the Madagascar project management system is transferred in the form of recorded processing histories, which become "computational recipes" to be verified, exchanged, and modified by users of the system.
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.
Brook for GPUs is a compiler and runtime implementation of the Brook stream programming language for modern graphics hardware. The goals for this project are to demonstrate general purpose programing on GPUs, to provide a useful tool for developers who want to run applications on GPUs, and to research the stream language programming model, streaming applications, and system implementations.
libagf is a fast, innovative implementation of adaptive or variable-bandwidth kernel-based estimators for statistical classification, PDF estimation, and interpolation/non-linear regression. It is written in C++ and includes simple, command line executables as well as easy-to-use libraries.
Wykobi is an efficient, robust, and simple to use multi-platform 2D/3D computational geometry library. Wykobi provides a concise, predictable, and deterministic interface for geometric primitives and complex geometric routines using and conforming to the ISO/IEC 14882:2003 C++ language specification. The design and structure of Wykobi lends itself to easy and seamless integration into projects of any scale that require a robust yet efficient 2D/3D computational geometry back-end.
Multipurpose Versatile Test Harness (MVTH) is a rapid prototyping and testing platform designed for computer vision algorithms. It benefits from the speed and low-level control of the C language while allowing for iterative tweaking and visualization during a running session (similar to Matlab). The end result is a core infrastructure that supports plugins and allows the rapid testing of ideas and comparisons of incremental improvements with results generated during previous plugin reloads. Plugins with machine/computer vision algorithms, image processing routines, and code for using particle filters (a statistical sampling approach) are included.
