* Changes that can potentially break compatibility:
+ image filtering functions throws exception on empty input
(voting results)
- Packaging changes:
* Stop mangling CMake diagnostic output, no dependency versions
end up in the packages anyway, drop opencv-build-compare.patch
* Set empty OPENCV_DOWNLOAD_TRIES_LIST, skip downloads even when
network is available during builds (e.g. local build).
* Drop upstream GLES patches:
+ 0001-Do-not-include-glx.h-when-using-GLES.patch
+ opencv-gles.patch - Disable Python 2 bindings for Tumbleweed. - Drop Jasper (i.e jpeg2k) support (boo#1130404, boo#1144260)
JasPer is unmaintained, CVEs are not being addressed (some issues
received patches submitted to the upstream github project, but are
not being merged, other CVEs are considered unfixable). openSUSE
follows other distros in dropping JasPer now (much later than
most others, incl. Debian). - Add webp build dependency to use system libwebp instead of bundled
one.
- Enable dispatch of AVX512 optimized code. - Update to 4.2.0
* DNN module:
+ Integrated GSoC project with CUDA backend: #14827
+ Intel® Inference Engine backend ( OpenVINO™ ):
- support for nGraph OpenVINO API (preview / experimental): #15537
* G-API module:
+ Enabled in-graph inference: #15090. Now G-API can express more
complex hybrid CV/DL algorithms;
- Intel® Inference Engine backend is the only available now,
support for DNN module will be added in the future releases.
+ Extended execution model with streaming support: #15216. Decoding,
image processing, inference, and post-processing are now pipelined
efficiently when processing a video stream with G-API.
+ Added tutorials covering these new features: Face analytics
pipeline and a sample Face beautification algorithm.
* Performance improvements:
+ SIMD intrinsics: StereoBM/StereoSGBM algorithms, resize, integral,
flip, accumulate with mask, HOG, demosaic, moments
+ Muti-threading: pyrDown
* And many other great patches from OpenCV community:
+ VideoCapture: video stream extraction (demuxing) through
FFmpeg backend.
+ VideoCapture: waitAny() API for camera input multiplexing
(Video4Linux through poll() calls).
+ (opencv_contrib) new algorithm Rapid Frequency Selective
Reconstruction (FSR): #2296 + tutorial.
+ (opencv_contrib) RIC method for sparse match interpolation: #2367.
+ (opencv_contrib) LOGOS features matching strategy: #2383.
* Breaking changes:
+ Disabled constructors for legacy C API structures.
+ Implementation of Thread Local Storage (TLS) has been improved to
release data from terminated threads. API has been changed.
+ Don't define unsafe CV_XADD implementation by default.
+ Python conversion rules of passed arguments will be updated in
next releases: #15915. - Limit build parallelism with limit_build, some ARM and PPC workers
have a high SMP/memory ratio and run out of memory otherwise.
- Apply memory constraints (3GB) to all architectures, avoid being
scheduled on very weak workers. - Update to 4.1.2
* DNN module:
+ Intel Inference Engine backend (OpenVINO):
- 2019R3 has been supported
- Support modern IE Core API
- New approach for custom layers management. Now all the OpenCV
layers fallbacks are implemented as IE custom layers which
helps to improve efficiency due less graph partitioning.
- High-level API which introduces dnn::Model class and set of
task-specific classes such dnn::ClassificationModel,
dnn::DetectionModel, dnn::SegmentationModel. It supports
automatic pre- and post-processing for deep learning networks.
* Performance improvements and platforms support:
+ MSA SIMD implementation has been contributed for MIPS platforms:

- 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.

- 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 (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= …”
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. opencv-qt5-doc h01-ch2c 1738840022
