G-API: Tutorial: Face beautification algorithm implementation
* Introduce a tutorial on face beautification algorithm
- small typo issue in render_ocv.cpp
* Addressing comments rgarnov smirnov-alexey
* Eltwise::DIV support in Halide backend

Add checks for empty operands in Matrix expressions that don't check properly
* Starting to add checks for empty operands in Matrix expressions that
don't check properly.
* Adding checks and delcarations for checker functions
* Fix signatures and add checks for each class of Matrix Expr operation
* Make it catch the right exception
* Don't expose helper functions to public API
* G-API: Added G-API Overview slides & its source code
- Sample code snippets are moved to separate files;
- Introduced a separate benchmark to measure Fluid/OpenCV
performance;
- Added notes on API changes (it is still a 4.0, not a 4.2 talk!)
- Added a "Metropolis" beamer download-n-build script.
* G-API: Addressed review issues on G-API overview slides
* imgproc: Prevent 1B overrun of 8C3 SIMD optimization
The fourth value read via v_load_q is essentially ignored,
but can cause trouble if it happens to cross page boundaries.
The final few iterations may attempt to read the most extreme
elements of S, which will read 1B beyond the array in most
aligment cases. Dynamically compute the stop. This could be
hoised from the loop, but will require a more extensive change.
Likewise, cleanup the iteration increment statements to make
it more obvious they do channel count (3) elements per pass.
This should resolve#16137
* imgproc(resize): extra check
dnn(eltwise): fix handling of different number of channels
* dnn(test): reproducer for Eltwise layer issue from PR16063

cuda4dnn(resize): process multiple channels each iteration
* resize bilinear: process multiple chans. per iter.
* remove unused headers
* correct dispatch logic
* resize_nn: process multiple chans. per iter.
* resize: HResizeLinear reduce duplicate work
There appears to be a 2x unroll of the HResizeLinear against k,
however the k value is only incremented by 1 during the unroll. This
results in k - 1 duplicate passes when k > 1.
Likewise, the final pass may not respect the work done by the vector
loop. Start it with the offset returned by the vector op if
implemented. Note, no vector ops are implemented today.
The performance is most noticable on a linear downscale. A set of
performance tests are added to characterize this. The performance
improvement is 10-50% depending on the scaling.
* imgproc: vectorize HResizeLinear
Performance is mostly gated by the gather operations
for x inputs.
Likewise, provide a 2x unroll against k, this reduces the
number of alpha gathers by 1/2 for larger k.
While not a 4x improvement, it still performs substantially
better under P9 for a 1.4x improvement. P8 baseline is
1.05-1.10x due to reduced VSX instruction set.
For float types, this results in a more modest
1.2x improvement.
* Update U8 processing for non-bitexact linear resize
* core: hal: vsx: improve v_load_expand_q
With a little help, we can do this quickly without gprs on
all VSX enabled targets.
* resize: Fix cn == 3 step per feedback
Per feedback, ensure we don't overrun. This was caught via the
failure observed in Test_TensorFlow.inception_accuracy.

Introducing the sample of Face Beautification algorithm implemented via Graph-API
* Introducing the sample of Face Beautification algorithm implemented via Graph-API
- 'gapi/samples/face_beautification.cpp' added
- FIXME added in 'gcpukernel.hpp'
* INF_ENGINE fix
- preprocessing clauses added not to run the sample without Inference Engine
* INF_ENGINE fix 2
- warnings removed
* Fixes
- checking IE version cut as there is no dependency
- some alignments fixed
- the comment about preprocessing commands fixed
* ie::backend() issue fix (according to dmatveev)
- as the sample needs the cv::gapi::ie::backend() to be defined regardless of having IE or not, there is its throw-error definition in `giebackend.cpp` now (by dmatveev)
- for the same reason, #includes in `giebackend.hpp` are fixed
- HAVE_INF_ENGINE check is removed from the sample
Implement Camera Multiplexing API
* IdideoCapture + two wrong function

Clarify stereoRectify() doc
The function stereoRectify() takes as input a coordinate transform between two cameras. It is ambiguous how it goes. I clarified that it goes from the second camera to the first.
* Use FlsAlloc/FlsFree/FlsGetValue/FlsSetValue instead of TlsAlloc/TlsFree/TlsGetValue/TlsSetValue to implment TLS value cleanup when thread has been terminated on Windows Vista and above
* Fix 32-bit build
* Fixed calling convention of cleanup callback
* WINAPI changed to NTAPI
* Use proper guard macro

* Change v_load_mirror_1 to use vec_revb for VSX
* Only use vec_revb in ISA3.0
* Removing vec_revb code since some of the older compilers don't fully support it.
* Use new v_reverse intrinsic and cleanup code.
* Ensure there are no alignment issues with copies
* Doc bugfix
The documentation page StereoBinaryBM and StereoBinarySGBM says that it returns a disparity that is scaled multiplied by 16. This scaling must be undone before calling reprojectImageTo3D, otherwise the results are wrong. The function reprojectImageTo3D() could do this scaling internally, maybe, but at least the documentation must explain that this has to be done.
* calib3d: update reprojectImageTo3D documentation
* calib3d: add StereoBM/StereoSGBM into notes list
- move TLS & instrumentation code out of core/utility.hpp
- (*) TLSData lost .gather() method (to dispose thread data on thread termination)
- use TLSDataAccumulator for reliable collecting of thread data
- prefer using of .detachData() + .cleanupDetachedData() instead of .gather() method
(*) API is broken: replace TLSData => TLSDataAccumulator if gather required
(objects disposal on threads termination is not available in accumulator mode)
Fixing bug with comparison of v_int64x2 or v_uint64x2
* Casting v_uint64x2 to v_float64x2 and comparing does NOT work in all cases. Rewrite using epi64 instructions - faster too.
* Fix bad merge.
* Fix equal comparsion for non-SSE4.1. Add test cases for v_int64x2 comparisons.
* Try to fix merge conflict.
* Only test v_int64x2 comparisons if CV_SIMD_64F
* Fix compiler warning.
* G-API: Doxygen documentatation for Async API
* G-API: Doxygen documentatation for Async API
- renamed local variable (reading parameter async) async ->
asyncNumReq in object_detection DNN sample
to avoid Doxygen erroneous linking the sample to cv::gapi::wip::async
documentation
* G-API-NG/Streaming: Introduced a Streaming API
Now a GComputation can be compiled in a special "streaming" way
and then "played" on a video stream.
Currently only VideoCapture is supported as an input source.
* G-API-NG/Streaming: added threading & real streaming
* G-API-NG/Streaming: Added tests & docs on Copy kernel
- Added very simple pipeline tests, not all data types are covered yet
(in fact, only GMat is tested now);
- Started testing non-OCV backends in the streaming mode;
- Added required fixes to Fluid backend, likely it works OK now;
- Added required fixes to OCL backend, and now it is likely broken
- Also added a UMat-based (OCL) version of Copy kernel
* G-API-NG/Streaming: Added own concurrent queue class
- Used only if TBB is not available
* G-API-NG/Streaming: Fixing various issues
- Added missing header to CMakeLists.txt
- Fixed various CI issues and warnings
* G-API-NG/Streaming: Fixed a compile-time GScalar queue deadlock
- GStreamingExecutor blindly created island's input queues for
compile-time (value-initialized) GScalars which didn't have any
producers, making island actor threads wait there forever
* G-API-NG/Streaming: Dropped own version of Copy kernel
One was added into master already
* G-API-NG/Streaming: Addressed GArray<T> review comments
- Added tests on mov()
- Removed unnecessary changes in garray.hpp
* G-API-NG/Streaming: Added Doxygen comments to new public APIs
Also fixed some other comments in the code
* G-API-NG/Streaming: Removed debug info, added some comments & renamed vars
* G-API-NG/Streaming: Fixed own-vs-cv abstraction leak
- Now every island is triggered with own:: (instead of cv::)
data objects as inputs;
- Changes in Fluid backend required to support cv::Mat/Scalar were
reverted;
* G-API-NG/Streaming: use holds_alternative<> instead of index/index_of test
- Also fixed regression test comments
- Also added metadata check comments for GStreamingCompiled
* G-API-NG/Streaming: Made start()/stop() more robust
- Fixed various possible deadlocks
- Unified the shutdown code
- Added more tests covering different corner cases on start/stop
* G-API-NG/Streaming: Finally fixed Windows crashes
In fact the problem hasn't been Windows-only.
Island thread popped data from queues without preserving the Cmd
objects and without taking the ownership over data acquired so when
islands started to process the data, this data may be already freed.
Linux version worked only by occasion.
* G-API-NG/Streaming: Fixed (I hope so) Windows warnings
* G-API-NG/Streaming: fixed typos in internal comments
- Also added some more explanation on Streaming/OpenCL status
* G-API-NG/Streaming: Added more unit tests on streaming
- Various start()/stop()/setSource() call flow combinations
* G-API-NG/Streaming: Added tests on own concurrent bounded queue
* G-API-NG/Streaming: Added more tests on various data types, + more
- Vector/Scalar passed as input;
- Vector/Scalar passed in-between islands;
- Some more assertions;
- Also fixed a deadlock problem when inputs are mixed (1 constant, 1 stream)
* G-API-NG/Streaming: Added tests on output data types handling
- Vector
- Scalar
* G-API-NG/Streaming: Fixed test issues with IE + Windows warnings
* G-API-NG/Streaming: Decoupled G-API from videoio
- Now the core G-API doesn't use a cv::VideoCapture directly,
it comes in via an abstract interface;
- Polished a little bit the setSource()/start()/stop() semantics,
now setSource() is mandatory before ANY call to start().
* G-API-NG/Streaming: Fix STANDALONE build (errors brought by render)
If an aravis camera is software triggered, a trigger needs to be explicitly sent using `arv_camera_software_trigger`, otherwise the camera will not grab any frames.
* New v_reverse HAL intrinsic for reversing the ordering of a vector
* Fix conflict.
* Try to resolve conflict again.
* Try one more time.
* Add _MM_SHUFFLE. Remove non-vectorize code in SSE2. Fix copy and paste issue with NEON.
* Change v_uint16x8 SSE2 version to use shuffles
* Adding support for vectorized masking for uchar/ushort.
* Fixing bug where mask was zeroing the dst. Improved the way to calculate
the mask and tweaked for further performance improvements.
* Fixing mask comparison test.
* Restricting to one channel.
* Adding support for 3 channels, switch old approach to start using HAL's
v_select.
