Intel OpenCV Library

• Intel Open Source Computer Vision Library
• It implements some popular algorithms of Image
  Processing and Computer Vision by C and C.
• This library is mainly aimed at real time
  computer vision.
• Support
• Miscrosoft Visual Studio 6.0 (OpenCV beta 3)
• Miscrosoft Visual Studio .NET 2003 (OpenCV beta
  3)
• Borland C BuilderX (OpenCV beta 4)
