Branch: CURRENT, Version: 3.3.0, Package name: opencv-3.3.0, Maintainer: anthony.mallet

OpenCV means Intel(R) Open Source Computer Vision Library. It is a
collection of C functions and a few C++ classes that implement many
popular Image Processing and Computer Vision algorithms.

OpenCV provides cross-platform middle-to-high level API that includes
about 300 C functions and a few C++ classes. Also there are Python
bindings to OpenCV. OpenCV has no strict dependencies on external
libraries, though it can use some (such as libjpeg, ffmpeg, GTK+ etc.)

OpenCV provides transparent interface to Intel(R) Integrated Performance
Primitives (IPP). That is, it loads automatically IPP libraries optimized
for specific processor at runtime, if they are available.

Log message:
Update graphics/opencv to 3.3.0.
Sync opencv-contrib-face too.

Main changes:

- DNN module from opencv_contrib was promoted to the main repository,
  improved and accelerated it a lot. An external BLAS implementation is
  not needed anymore. For GPU there is experimental DNN acceleration using
  Halide (http://halide-lang.org).
- OpenCV can now be built as C++ 11 library using the flag ENABLE_CXX11.
  Some cool features for C++ 11 programmers have been added.
- We've also enabled quite a few AVX/AVX2 and SSE4.x optimizations in
  the default build of OpenCV thanks to the feature called 'dynamic
  dispatching'. The DNN module also has some AVX/AVX2 optimizations.
- Intel Media SDK can now be utilized by our videoio module to do
  hardware-accelerated video encoding/decoding. MPEG1/2, as well as
  H.264 are supported.
- Embedded into OpenCV Intel IPP subset has been upgraded from 2015.12
  to 2017.2 version, resulting in ~15% speed improvement in our core &
  imgproc perf tests.

Highlights:

     * Results from 11 GSoC 2016 projects have been submitted to the
       library, 9 of them have been integrated already, 2 still pending
       (the numbers below are the id's of the Pull Requests in opencv or
       opencv_contrib repository):
          + Ambroise Moreau (Delia Passalacqua) - sinusoidal patterns for
            structured light and phase unwrapping module (711)
          + Alexander Bokov (Maksim Shabunin) - DIS optical flow
            (excellent dense optical flow algorithm that is both
            significantly better and significantly faster than Farneback's
            algorithm - our baseline), and learning-based color constancy
            algorithms implementation (689, 708, 722, 736, 745, 747)
          + Tyan Vladimir (Antonella Cascitelli) - CNN based tracking
            algorithm (GOTURN) (718, 899)
          + Vladislav Samsonov (Ethan Rublee) - PCAFlow and Global Patch
            Collider algorithms implementation (710, 752)
          + Jo o Cartucho (Vincent Rabaud) - Multi-language OpenCV
            Tutorials in Python, C++ and Java (7041)
          + Jiri Horner (Bo Li) - New camera model and parallel processing
            for stitching pipeline (6933)
          + Vitaliy Lyudvichenko (Anatoly Baksheev) - Optimizations and
            improvements of dnn module (707, 750)
          + Iric Wu (Vadim Pisarevsky) - Base64 and JSON support for file
            storage (6697, 6949, 7088). Use names like
            `"myfilestorage.xml?base64"` when writing file storage to
            store big chunks of numerical data in base64-encoded form.
          + Edgar Riba (Manuele Tamburrano, Stefano Fabri) - tiny_dnn
            improvements and integration (720: pending)
          + Yida Wang (Manuele Tamburrano, Stefano Fabri) - Quantization
            and semantic saliency detection with tiny_dnn
          + Anguelos Nicolaou (Lluis Gomez) - Word-spotting CNN based
            algorithm (761: pending)
