G-API Serialization routines
* Serialization backend in tests, initial version
* S11N/00: A Great Rename
- "Serialization" is too long and too error-prone to type,
so now it is renamed to "s11n" everywhere;
- Same applies to "SRLZ";
- Tests also renamed to start with 'S11N.*' (easier to run);
- Also updated copyright years in new files to 2020.
* S11N/01: Some basic interface segregation
- Moved some details (low-level functions) out of serialization.hpp;
- Introduced I::IStream and I::OStream interfaces;
- Implemented those via the existing [De]SerializationStream classes;
- Moved all operators to use interfaces instead of classes;
- Moved the htonl/ntohl handling out of operators (to the classes).
The implementation didn't change much, it is a subject to the further
refactoring
* S11N/02: Basic operator reorg, basic tests, vector support
- Reorganized operators on atomic types to follow >>/<< model
(put them closer in the code for the respective types);
- Introduce more operators for basic (scalar) types;
- Drop all vector s11n overloads -- replace with a generic
(template-based) one;
- Introduced a new test suite where low-level s11n functionality
is tested (for the basic types).
* S11N/03: Operators reorganization
- Sorted the Opaque types enum by complexity;
- Reorganized the existing operators for basic types, also ordered by
complexity;
- Organized operators in three groups (Basics, OpenCV, G-API);
- Added a generic serialization for variant<>;
- Reimplemented some of the existing operators (for OpenCV and G-API
data structures);
- Introduced new operators for cv::gimpl data types. These operators
(and so, the data structures) are not yet used in the graph
dump/reconstruction routine, it will be done as a next step.
* S11N/04: The Great Clean-up
- Drop the duplicates of GModel data structures from the
serialization, serialize the GModel data structures themselve
instead (hand-written code replaced with operators).
- Also removed usuned code for printing, etc.
* S11N/05: Internal API Clean-up
- Minimize the serialization API to just Streams and Operators;
- Refactor and fix the graph serialization (deconstruction and
reconstruction) routines, fix data addressing problems there;
- Move the serialization.[ch]pp files to the core G-API library
* S11N/06: Top-level API introduction
- !!!This is likely the most invasive commit in the series!!!
- Introduced a top-level API to serialize and deserialize a GComputation
- Extended the compiler to support both forms of a GComputation:
an expession based and a deserialized one. This has led to changes in
the cv::GComputation::Priv and in its dependent components (even the
transformation tests);
- Had to extend the kernel API (GKernel) with extra information on
operations (mainly `outMeta`) which was only available for expression
based graphs. Now the `outMeta` can be taken from kernels too (and for
the deserialized graphs it is the only way);
- Revisited the internal serialization API, had to expose previously
hidden entities (like `GSerialized`);
- Extended the serialized graph info with new details (object counter,
protocol). Added unordered_map generic serialization for that;
- Reworked the very first pipeline test to be "proper"; GREEN now, the rest
is to be reworked in the next iteration.
* S11N/07: Tests reworked
- Moved the sample pipeline tests w/serialization to
test the public API (`cv::gapi::serialize`, then
followed by `cv::gapi::deserialize<>`). All GREEN.
- As a consequence, dropped the "Serialization" test
backend as no longer necessary.
* S11N/08: Final touches
- Exposed the C++ native data types at Streams level;
- Switched the ByteMemoryIn/OutStreams to store data in `char`
internally (2x less memory for sample pipelines);
- Fixed and refactored Mat dumping to the stream;
- Renamed S11N pipeline tests to their new meaning.

- opencv_gapi module is linked with opencv_video module (optional dependency)
- kernels added to a new cv::gapi::video namespace and a brand new files created to provide gapi_video environment
- there are 2 different kernels as G-API should provide GMat AND GArray<GMat> implementation: cv::calcOptFlowPyrLK doesn't calculate pyramids if vector<Mat> is given so just the cast GMat -> GArray<GMat> wouldn't represent all the cv:: functionality
- tests to check both kernels (based on cv::video tests for cv::calcOpticalFlowPyrLK())
- tests for internal purposes added
- vectors<T> comparison in tests implemented
- new (and old too) common test structures refactored to avoid code copypasting
- "modules/gapi/test/common/gapi_video_tests_common.hpp" created to share some code snippets between perf and acc tests and avoid code copypasting
* 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)
G-API: add transformation logic to GCompiler
* Introduce transformation logic to GCOmpiler
* Remove partialOk() method
* Fix minor issues
* Refactor code according to code review
1. Re-design matchPatternToSubstitute logic
2. Update transformations order
3. Replace check_transformations pass with a
one time check in GCompiler ctor
* Revert unused nodes handling in pattern matching
* Address minor code review issues
* Address code review comments:
1) Fix some mistakes
2) Add new tests for endless loops
3) Update GCompiler's transformations logic
* Simplify GCompiler check for endless loops
1. Simplify transformations endless loops check:
- Original idea wasn't a full solution
- Need to develop a good method (heuristic?) to find loops
in general case (TODO)
2. Remove irrelevant Endless Loops tests
3. Add new "bad arg" tests and unit tests
* Update comments
* - headers in "infer/" and "infer/ie/" folders are included into gapi_ext_hdrs;
+ because of that a few #includes are required in the headers
- HAVE_INF_ENGINE flag check in headers "infer/ie.hpp" and "infer/ie/util.hpp" is deleted
* - the "ie/util.hpp" header is a private header now as it's used for tests; it's been moved to the scr directory to the place next to the implementation file "ie/giebackend.cpp"
- the path to this header in files "ie/giebackend.cpp" and "test/infer/gapi_infer_ie_test.cpp" is updated
- As it's private header now and explicitly depends on IE, the "HAVE_INF_ENGINE" flag check is returned
* G-API-NG/API: Introduced inference API and IE-based backend
- Very quick-n-dirty implementation
- OpenCV's own DNN module is not used
- No tests so far
* G-API-NG/IE: Refined IE backend, added more tests
* G-API-NG/IE: Fixed various CI warnings & build issues + tests
- Added tests on multi-dimensional own::Mat
- Added tests on GMatDesc with dimensions
- Documentation on infer.hpp
- Fixed more warnings + added a ROI list test
- Fix descr_of clash for vector<Mat> & standalone mode
- Fix build issue with gcc-4.8x
- Addressed review comments
