Overview

What is OpenCV?

OpenCV is “Open Source Computer Vision Library”. OpenCV is developed by Intel and many opensource developers. This library include many useful function for computer vision, such as object-detection.

OpenCV is developed at sourceforge.net

What is Ruby/OpenCV?

Ruby/OpenCV is manual Wrapper of OpenCV (not use SWIG). This library seem to be Ruby.

  • object-oriented

  • support Garbage Collection by Ruby

Ruby/OpenCV is developed rubyforge.org/projects/opencv (Official) and blueruby.mydns.jp/pages/opencv (Japanese)
