This release features n-dimensional connected component analysis, n-dimensional histograms and weighted histograms, maps and warps with n-dimensional elements, summed area tables (integrals), opt-out range checks for histograms/maps/warps/unmask, and uniform random number generators (floating-point as well as integer). While HornetsEye is still compatible with Ruby-1.8.6 it can now be compiled for Ruby 1.9.1p243!... read more

The core of the HornetsEye library was rewritten. The new core features a much more versatile type system, extended element selectors, array views, and tensor operations. Maps, warps, and masks now work on single elements as well as sub-arrays. A conversion to OpenCV::CvMat and back was implemented. Furthermore a GNUplot example was added.... read more

The framerate of the V4L2 was improved. Fast generation of index-arrays was added. Allocated memory is not cleared by default any more for increased performance. Compiled methods are cached so they don't need to be compiled again. Furthermore weighted histograms, Fast Fourier Transforms, and an implementation of the Mean Shift algorithm where added.... read more

Now Hornetseye also runs on MS Windows. Currently Hornetseye for Windows is pretty basic since it does not have Video-I/O and cannot yet display images without the help of Qt4. If you are still interested you can already download a big package with installers for Ruby, HornetsEye, Qt4, and a lot more.

This is the first release of HornetsEye appearing on SourceForge. HornetsEye tries to bring existing functionality of GPL software related to computer vision together in Ruby. HornetsEye aims at giving you a strong basis for developing real-time computer vision algorithms. This project shows that it is possible to make use of the flexibility of a dynamically typed language like Ruby without sacrificing runtime efficiency.... read more
