Rvision 0.6.0
New features
We now have a changelog (yes, I know, finally).
A large portion of the code base has been rewritten for improving performance
and facilitating code maintenance (hopefully).
In-place operations have been reworked to allow for saving results in target
images for more flexibility while maintaining performance.
GPU support has been added wherever possible. Stupid-fast mode enabled on
compatible hardware :-)
An experimental dynamic queuing system operating on a separate thread has been
introduced to allow for reading frames in parallel with image processing on the
main R thread.
New, hopefully more useful vignettes have been added.
More OpenCV functions are now accessible through Rvision (e.g., histogram
equalization).
