GPGPU means General Purpose computation on Graphics Processing Units. On this page a few basic programs and libraries are presented that show how the GPU can be used for computer vision tasks like edge detection.


The following hardware and software is needed to run the programs:

  • A graphics card (and driver) that supports OpenGL 2.0
  • The OpenGL Utility Toolkit (GLUT)
  • C for Graphics (Cg)
  • C++ (e.g. Visual C++ 8.0)
