    * Persistence (storing and loading structured data to/from XML, YAML or JSON)
      in the core module has been completely reimplemented.
    * OpenCV is now C++11 library and requires C++11-compliant compiler.
      Thanks to the extended C++11 standard library, we could get rid of hand-crafted
      cv::String and cv::Ptr. Now cv::String == std::string and cv::Ptr is a thin
      wrapper on top of std::shared_ptr. Also, on Linux/BSD for cv::parallel_for_
      we now use std::thread's instead of pthreads.

      efficient image processing, based on lazy evaluation and on-fly construction.
    * Performance improvements
      A few hundreds of basic kernels in OpenCV have been rewritten using so-called
      "wide universal intrinsics". Those intrinsics map to SSE2, SSE4, AVX2, NEON or
      VSX intrinsics, depending on the target platform and the compile flags.
    * QR code detector and decoder have been added to opencv/objdetect module.
    * The popular Kinect Fusion algorithm has been implemented, optimized for CPU and
      GPU (OpenCL), and integrated into opencv_contrib/rgbd module.
    * Very efficient and yet high-quality DIS dense optical flow algorithm has been
      moved from opencv_contrib to opencv, video module. See the example.
    * The slower TV L1 optical flow algorithm has been moved to opencv_contrib.

    - A lot of new functionality has been introduced during Google
      Summer of Code 2015:

      Reconstruction” – opencv_contrib/ccalib module
      (Baisheng Lai, Bo Li)

      + “Stereo correspondence improvements” – opencv_contrib/stereo
      module (Mircea Paul Muresan, Sergei Nosov)
      + “Structured-Light System Calibration” –
      opencv_contrib/structured_light (Roberta Ravanelli,
      Delia Passalacqua, Stefano Fabri, Claudia Rapuano)
      + “Chessboard+ArUco for camera calibration” –
      opencv_contrib/aruco (Sergio Garrido, Prasanna, Gary Bradski)
      + “Implementation of universal interface for deep neural
      network frameworks” – opencv_contrib/dnn module
      (Vitaliy Lyudvichenko, Anatoly Baksheev)
      + “Recent advances in edge-aware filtering, improved SGBM
      stereo algorithm” – opencv/calib3d and opencv_contrib/ximgproc
      (Alexander Bokov, Maksim Shabunin)
      + “Improved ICF detector, waldboost implementation” –
      opencv_contrib/xobjdetect (Vlad Shakhuro, Alexander Bovyrin)
      + “Multi-target TLD tracking” – opencv_contrib/tracking module
      (Vladimir Tyan, Antonella Cascitelli)
      + “3D pose estimation using CNNs” – opencv_contrib/cnn_3dobj
      (Yida Wang, Manuele Tamburrano, Stefano Fabri)
    - Many great contributions made by the community, such as:
      + Support for HDF5 format
      + New/Improved optical flow algorithms
      + Multiple new image processing algorithms for filtering,
      segmentation and feature detection
      + Superpixel segmentation and much more
    - IPPICV is now based on IPP 9.0.1, which should make OpenCV
      even faster on modern Intel chips
    - opencv_contrib modules can now be included into the
      opencv2.framework for iOS
    - Newest operating systems are supported: Windows 10 and
      OSX 10.11 (Visual Studio 2015 and XCode 7.1.1)
    - Interoperability between T-API and OpenCL, OpenGL, DirectX and
      Video Acceleration API on Linux, as well as Android 5 camera.
    - HAL (Hardware Acceleration Layer) module functionality has been
      moved into corresponding basic modules; the HAL replacement
      mechanism has been implemented along with the examples
  - Removed improve-sphinx-search.diff, opencv-altivec-vector.patch,
    opencv-pkgconfig.patch and opencv-samples.patch, fixed upstream.
  - Fixed opencv-qt5-sobump.diff, opencv-build-compare.patch,
    opencv-gcc5.patch and opencv-gles.patch.
  - Version OpenCV 3.0.0
    + ~1500 patches, submitted as PR @ github. All our patches go
      the same route.
    + opencv_contrib (
      repository has been added. A lot of new functionality is there
      already! opencv_contrib is only compatible with 3.0/master,
      not 2.4. Clone the repository and use “cmake …
    - D OPENCV_EXTRA_MODULES_PATH=<path_to opencv_contrib/modules> …”
      to build opencv and opencv_contrib together.
    + a subset of Intel IPP (IPPCV) is given to us and our users free
      of charge, free of licensing fees, for commercial and
      non-commerical use. It’s used by default in x86 and x64 builds
      on Windows, Linux and Mac.
    + T-API (transparent API) has been introduced, this is transparent
      GPU acceleration layer using OpenCL. It does not add any
      compile-time or runtime dependency of OpenCL. When OpenCL is
      available, it’s detected and used, but it can be disabled at
      compile time or at runtime. It covers ~100 OpenCV functions.
      This work has been done by contract and with generous support
      from AMD and Intel companies.
    + ~40 OpenCV functions have been accelerated using NEON intrinsics
      and because these are mostly basic functions, some higher-level
      functions got accelerated as well.
    + There is also new OpenCV HAL layer that will simplifies creation
      of NEON-optimized code and that should form a base for the
      open-source and proprietary OpenCV accelerators.
    + The documentation is now in Doxygen:
    + We cleaned up API of many high-level algorithms from features2d,
      calib3d, objdetect etc. They now follow the uniform
      “abstract interface – hidden implementation” pattern and make
      extensive use of smart pointers (Ptr<>).
    + Greatly improved and extended Python & Java bindings (also,
      see below on the Python bindings), newly introduced Matlab
      bindings (still in alpha stage).
    + Improved Android support – now OpenCV Manager is in Java and
      supports both 2.4 and 3.0.
    + Greatly improved WinRT support, including video capturing and
      multi-threading capabilities. Thanks for Microsoft team for this!
    + Big thanks to Google who funded several successive GSoC programs
      and let OpenCV in. The results of many successful GSoC 2013 and
      2014 projects have been integrated in opencv 3.0 and
      opencv_contrib (earlier results are also available in
      OpenCV 2.4.x). We can name:
    - text detection
    - many computational photography algorithms (HDR, inpainting,
      edge-aware filters, superpixels, …)
    - tracking and optical flow algorithms
    - new features, including line descriptors, KAZE/AKAZE
    - general use optimization (hill climbing, linear programming)
    - greatly improved Python support, including Python 3.0 support,
      many new tutorials & samples on how to use OpenCV with Python.
    - 2d shape matching module and 3d surface matching module
    - RGB-D module
    - VTK-based 3D visualization module
    - etc.
    + Besides Google, we enjoyed (and hope that you will enjoy too)
      many useful contributions from community, like:
    - biologically inspired vision module
    - DAISY features, LATCH descriptor, improved BRIEF
    - image registration module
    - etc.

    * A lot of good stuff from the Google Summer of Code 2012 has been
      integrated; this was a very productive summer!
    * Significantly improved and optimized Android and iOS ports.
    * Greatly extended GPU (i.e. CUDA-based) module.
    * The brand new ocl (OpenCL-based) module that unleashes GPU power
      also for AMD and Intel GPU users. It’s not included into the
      binary package, since there are different SDKs, and it’s not
      turned on by default. You need to run CMake and turn on
      “WITH_OPENCL”. Also, please note that this is very first version
      of the module, so it may be not very stable and not very
    * Much better performance on many-core systems out of the box. You
      do not need TBB anymore on MacOSX, iOS and Windows. BTW, the
      binary package for Windows is now built without TBB support.
      Libraries and DLLs for Visual Studio 2010 use the Concurrency
    * About 130 bugs have been fixed since 2.4.2.
