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.
The LTI-Lib is an object oriented library with algorithms and data structures frequently used in image processing and computer vision. It was developed at the RWTH-Aachen University as a part of many research projects on computer vision dealing with robotics, object recognition, sign language, and gesture recognition. It provides an object oriented C++ library that includes fast algorithms, which can be used in real applications.
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.
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.
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.
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.
CellProfiler is a system for analyzing cell images. It is designed for biologists without training in computer vision or programming to make quantitative measurements of cells in thousands of images automatically. It is implemented using Matlab, but compiled standalone versions are available.
