VisionLab is a set of Visual C++ components for basic computer vision. The components allow rapid development of fully featured motion detection applications for the security industry with almost zero lines of program code. It includes Canny edge detection, Adaptive Threshold, Hough Lines, and Contour Finder components. VisionLab also includes video capturing components based on both Video For Windows(VFW), and DirectShow, so no additional components are needed in order to start building motion detection applications. Free for non-commercial use.
