Darwin Wallet enables blind and visually impaired users to quickly recognize paper money. It uses the phone's camera to detect currency denominations for U.S., U.K., Canadian, European Union, and Australian bills. Simply hold the bill in front of the phone's camera, and the app will speak its value. The app uses the phone's camera and OpenCV (via Android NDK) to analyze and identify the currency image.
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.
OpenALPR is an automated license plate recognition library that analyzes images and identifies license plates. The output is the text representation of any license plate characters found in the image. It uses OpenCV computer vision libraries to recognize and analyze the plate images, and the Tesseract OCR library and a specially trained character set to recognize characters.
Qt-based library with functionality to create highly efficient and fully graphical applications, oriented to computer vision, image processing, and scientific computation. The library features an homogeneous and well documented object-oriented API, with wrapping methods for high performance functionality from libraries such as OpenCV, GSL, CGAL, IPP, BLAS, LAPACK, or Octave library.
Screwdriver++ is a package with various tools for the C++ programmer in Unix environments. It contains classes for time measurement, image and file manipulation, and arbitrary precision arithmetics. Timer is a class for measuring time intervals with millisecond accuracy. Image is a class that uses OpenCv to manipulate images. File is a class to manipilate file input and output in various formats. Number is a class to manipulate arbitrary precision arithmetics.
SecureCam is a video surveillance system with a nice GUI. It supports multiple camera and video file inputs. It detects motion in input video using fast algorithms. Alarm notification is provided by email, alarm sound, and video recording. Currently, only a Windows installer is provided, but the source can be compiled on Linux.
SysopView shows information in a visually attractive way, like computers in movies do. The idea is that it can show information relevant to system administrators non-comprehensible for non-technical personnel, while still looking attractive even if you don't know what is shown. The current version can show nagios status data, webcam streams (mjpeg, jpeg, and video4Linux), and VNC, has a built-in terminal emulator in which regular text applications can be run, can sniff the network (including remotely) and dissect streams and show pictures which are sniffed, can show external bitmaps (from, for example, mrtg and rrdtool), and can scroll text (currently showing output of rssfeeds).
Trusion is a physical intrusion system that uses users' Webcams to detect motion, which serves as an indicator to start recording video. Optionally, users can choose to have the program upload the videos to an FTP server in the unfortunate event your computer gets stolen or the perpetrator manages to delete the user's local video files. This is a very new project that is enthusiastically welcoming new contributors and their ideas. This project was build using Qt and OpenCV.
