Comment (by bdubbs):
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:
