Rvision 0.8.0

Full Changelog: https://github.com/swarm-lab/Rvision/compare/v0.7.0…v0.8.0

New features

  • Add camera calibration functions and tutorial.
  • Add mask to ECC and minMaxLoc functions.
  • Add line detection with probabilistic Hough transform.
  • Add goodFeaturesToTrack function (finds the most prominent corners in an image).

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).
