OpenCV (Open Source Computer Vision Library) is a library of programming functions mainly for real-time computer vision. [2] Originally developed by Intel, it was later supported by Willow Garage, then Itseez (which was later acquired by Intel [3]).
VXL, the Vision-something-Library, is a large collection of open source C++ libraries for computer vision.The idea of the naming is to replace X with one of many letters to obtain the smaller library names, i.e. G (VGL) is a geometry library, N (VNL) is a numerics library, I (VIL) is an image processing library, etc.
A C++ implementation is available on GitHub, which has also been ported to OpenCV and included in the Camera Calibration and 3D Reconstruction module (SolvePnP function). [ 12 ] Using RANSAC
For example, if we have two three-by-three matrices, the first a kernel, and the second an image piece, convolution is the process of flipping both the rows and columns of the kernel and multiplying locally similar entries and summing.
The library was tested successfully with OpenCV 2.4.10. BGSLibrary includes the original LBP implementation for motion detection [12] as well as a new LBP operator variant combined with Markov Random Fields [13] with improved recognition rates and robustness. dlib, an open source C++ library: implementation. scikit-image, an open source Python ...

Cascade classifiers are available in OpenCV, with pre-trained cascades for frontal faces and upper body. Training a new cascade in OpenCV is also possible with either haar_training or train_cascades methods. This can be used for rapid object detection of more specific targets, including non-human objects with Haar-like features. The process ...
Users will find many similarities between the two libraries, for example what is beginShape() in Processing is ofBeginShape() in openFrameworks. The openFrameworks wiki includes an article for people coming to openFrameworks from Processing. [12] Another similar project is Cinder, which is also a C++ library framework for creative programming ...
