Highlights of this release:

DNN module:

Integrated GSoC project with CUDA backend:

Intel® Inference Engine backend ( OpenVINO™ ): support for nGraph OpenVINO API (preview / experimental):

G-API module:

Enabled in-graph inference: 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:

(opencv_contrib) LOGOS features matching strategy:

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:
