What is OpenCV?

What is OpenCV?

• Open source computer vision library in C/C++. Wrappers are provided for languages including Python.
• Optimized and intended for real-time applications.

What is it used for?

• Image data manipulation
• Image and video I/O
• Matrix and vector manipulation and linear algebra routines (products, solvers, eigenvalues, SVD).
• Basic image processing (filtering, edge detection, corner detection, sampling and interpolation, color conversion, morphological operations, histograms, image pyramids).
• Structural analysis (connected components, contour processing, distance transform, various moments, template matching, Hough transform, polygonal approximation, line fitting, ellipse fitting, Delaunay triangulation).
• Motion analysis (optical flow, motion segmentation, tracking).
• Object recognition (eigen-methods, HMM).
