- Update to version 4.0.0
* A lot of C API from OpenCV 1.x has been removed. The affected modules are
objdetect, photo, video, videoio, imgcodecs, calib3d.
* 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.
* DNN improvements
* Completely new module opencv_gapi has been added. It is the engine for very
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.

OSX 10.11 (Visual Studio 2015 and XCode 7.1.1)

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 (http://github.com/itseez/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: http://docs.opencv.org/master/
+ 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.
- Reduce build-compare noise
opencv-build-compare.patch
- Remove BuildRequirement for python-sphinx in SLE12, since it's
not available there and it's not a mandatory requirement.
- Reduce differences between two spec files
- Use pkgconfig for ffmpeg BuildRequires
- Update improve-sphinx-search.diff for new python-Sphinx(1.3.1)
* now that sphinx-build disallow executing without arguments and
give you "Insufficient arguments" error, use "sphinx-build -h"
instead
* the default usages output ie. sphinx-build(or --help) no longer
are standard error but standard output, drop OUTPUT_QUIET and
add OUTPUT_VARIABLE throws the output to SPHINX_OUTPUT as well
- support gcc 5 (i.e. gcc versions without minor version):
opencv-gcc5.patch
- Update to OpenCV 2.4.11 - can't find NEWS or Changelog
merely collecting bug fixes while 3.0 is in the making, 2.4.11
didn't even make it on their web page, it's only on download
server
- remove opencv-underlinking.patch as obsolete
- remove upstream patch bomb_commit_gstreamer-1x-support.patch
- commenting out opencv-pkgconfig.patch - possibly it requires a rebase,
but the problem it tries to solve is unclear
- Add specific buildrequires for libpng15, so that we are
building against the system provided libpng.
- Update to OpenCV 2.4.9
More info at:
http://opencv.org/opencv-2-4-9-is-out.html

* bomb_commit_gstreamer-1x-support.patch

- Update to OpenCV 2.4.4
More info at:

The brief list of changes:
* OpenCV Java bindings are ported from Android to desktop Java!
Actually any JVM language will work, see Tutorial for details,
and Java or Scala code samples.
* Android application framework, samples, tutorials, and OpenCV
Manager are improved.
* Optimizations for the new NVIDIA Kepler architecture, CARMA
platform support and other new optimizations in CUDA.
* OpenCL module now builds successfully with various SDKs (from
AMD, NVIDIA, Intel and Apple) and runs well on different GPUs
(AMD, NVidia, Intel HD4000). A lot of new functionality has been
added, tons of bugs fixed, performance of many functions has
been significantly improved.
* 100+ reported problems have been resolved since 2.4.3, thanks
everybody who participated!
- Drop the buildrequire for libxine
- Update to OpenCV 2.4.3

The nicely formatted changelog can be seen here:
http://code.opencv.org/projects/opencv/wiki/ChangeLog;
here are the highlights:
* 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
functional.
* 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
framework.
* About 130 bugs have been fixed since 2.4.2.
* Since 2.4.3rc we fixed several more problems, in particular some
compile problems with iOS 6 SDK.
