| − | '''[http://www.wedesoft.demon.co.uk/hornetseye-api/ HornetsEye]''' also is an attempt to use the Mimas library and create a ''minimalistic'' and ''consistent'' real-time computer vision library.
| |
| − | * '''minimalistic''': The library is focused on real-time computer vision. Existing libraries are being made used of.
| |
| − | * '''consistent''':: A non-redundant set of data-types is used. Also the library tries to stay consistent with existing libraries.

| − | The [http://www.wedesoft.demon.co.uk/hornetseye-api/files/webcamapp-txt.html Linux webcam application] uses [[HornetsEye]], [http://rubyforge.org/projects/rmagick/ RMagick], and [http://rubyforge.org/projects/korundum/ qt4-ruby] (there also is a [http://www.wedesoft.demon.co.uk/hornetseye-api/files/vfwcamapp-txt.html Windows webcam] already).
| + | '''[http://www.wedesoft.demon.co.uk/hornetseye-api/ HornetsEye]''' is a Ruby-extension for developing video processing and real-time computer vision software under GNU/Linux offering interfaces to do image- and video-I/O with RMagick, Xine, firewire digital camera, and video for Linux. A new class of unprecedented solutions and a new way of working becomes conceivable when applying a dynamically typed, object-oriented language like Ruby to computer vision. |
