| |
| − | After installation you can use '''HornetsEye''' without having to compile or link anything! You can even develop computer vision
| |
| − | algorithms on the command-line using Interactive Ruby (irb). HornetsEye offers image file-I/O, video input, access to webcams and
| |
| − | framegrabbers, access to firewire digital cameras, edge detection, corner detection, user-defined filters. It thightly integrates
| |
| − | with existing Ruby extensions.
| |
| − |
| |
| − | '''HornetsEye''' is maybe the first free software project providing a '''solid platform for implementing real-time computer vision software'''
| |
| − | in a scripting language. The platform potentially could be used in '''robotic applications''', '''industrial automation''' as well
| |
| − | as in '''microscopy''' and the '''life sciences'''.
| |
| − |
| |
| − | The logo was created using [http://gimp.org/ GIMP] and it shows a honeycomb structure as you would find on an insect's compound eye. A hornet is capable of navigating and detecting objects with the limited resolution of its [http://en.wikipedia.org/wiki/Compound_eye compound eyes].

| |
| − | ==Webcam==
| |
| − | 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).
| |

| |
| − | See [http://www.wedesoft.demon.co.uk/hornetseye-api/files/inputgrey-txt.html Hornetseye homepage] for more examples.
| |
| − |
| |
| − | ==Phase Correlation==
| |
| − | The [http://www.wedesoft.demon.co.uk/hornetseye-api/files/phasecorrelation-txt.html phase correlation example] is an implementation of the [http://en.wikipedia.org/wiki/Phase_correlation phase correlation] for aligning images.
| |
| − | The code depends on [[HornetsEye]], [http://rubyforge.org/projects/rmagick/ RMagick] and [http://rubyforge.org/projects/narray/ NArray-fftw3].
