OpenCVRelease 2.2 Nov2010

• OpenCV 2.2 is released

  • Teasers already far along AFTER this release:

    • Panoramic Stitching
    • Circular dots calibration patterns (they are more accurate)
    • Turning any picture into a calibration pattern

    • WAY more GPU support

In 2.2

Key release updates:

Key: = Done; = Ongoing, probably make it; = Behind; = Cut from list/will not make it.

1. Improved camera calibration (wide-angle lens support ...)

   • This is now the default, flags can be used to fix the new parameters of the ratio model

2. Reorganized documentation (that reflects the new OpenCV structure)

   • Documentation auto-generated for wiki -- include user feedback page for each function.

3. Google test support, sample tests (so that users can add new tests together with the new functionality)

   • Google test is integrated and works, but tests are not written in it yet

4. Active work Python support extended to the new C++ functionality & MLL

   • Need to look at pyopencv No, Vadim wrote a parser so that OpenCV now has a complete python interface and compatibility with numpy arrays

5. Android support in the build system, (and optionally iphone)

6. More bugfixes (reported in the bug tracker).

   • Exept Highgui issues. Some camera issues on linux, but we don't have these, so we can't fix yet
   • Python binding tickets -- some should be analyzed by James

7. Finish features2d interface for one to many image matching (in progress by Maria)

   • Add BRIEF descriptor from ROS (roscd brief_descriptor)

8. Include interface to PASCAL Visual Object Challenge (VOC) and bag of words matching done by Ken Chatfield

9. Include latent SVM detector done by Nizhny U (in progress, this depends on U folks, they are aware of tight schedule, agreed to ratify external API with us by Sep 20)

   • We need external API fixed and a sample written

   • test code ... (but fails on some platforms)

10. Add algorithmic/timing tests and documentation on features2d

    • Part of this awaits ratification (cmatch 1 image against multiple images)

11. Replace inclusions of old OpenCV headers by new ones (obtained after OpenCV restructuring) throughout the library to optimize building time.

    • Some tests still include old style headers ... plan to fix by release

12. 3 inline camera stereo.

    • Needs discussion with Kurt about when the camera is too far out of left<=>right image planes. Then there is a problem with scale factors

13. Updated FLANN (Fast Library for Approximate Nearest Neighbors -- scalable machine learning) is incorporated into OpenCV -- it handles small vectors better.

14. cout << cv::Mat. Supports output to opencv, python, numpy and matlab formats

15. Gary is adding documentation print out to the top of each and every sample program. T E D I O U S

• Release date is end of November

  • Release waas 3 weeks due to delay in completing python interface (for missing C functions but mainly for ML functions) and clean out all important bugs
