G-API external backend development (#13943)
* Moved HostCtor and ConstVal from gapi_priv.hpp to objref.hpp
* Added gmodel_priv.hpp, added export of symbols from gmodel.hpp
* Added export of binInArg and bindOutArg
* Renamed gapi_priv.*pp -> gorigin.*pp
* Added a fixme on collecting exports inside one class
Allow nodes produced after some operation to be
"unused": not being an output and not being used
as inputs to other operations
Add fluid test to cover this case
* Add Sobel kernel which returns both dx and dy
* Splice dx and dy and extend add_border function
Also change some tests parameters
* Add borderValue parameter in test
* Introduces fluid kernel for sobelxy
Adds tests (basic and performance) on new backend
* Introduces BufHelper struct for some arithmetic
GAPI: Add normalize kernel in G-API (#13721)
* Add normalize kernel in G-API
In addition add several tests on new kernel
* Fix indentations and normalize test structure
* Move normalize kernel from imgproc to core
Set default parameter ddepth to -1
* Fix alignment
* Return vector of MetaArg instead of MatDesc and fix test with ADL check
* Fix construction of vector
* Change names and tests according to review
Also add GAPI_EXPORTS prefix for two ostream operators
* Add version of descr_of function taking vector of Mat
* Overload descr_of function for cv::Mat
* Add template function instead of copypasting and change tests a little
More fixes for G-API tests (#13251)
* scalar comparator and more fixes for tests
* add weighted aligned
* white space
* more white space
* Add weighted test accuracy check enabled

* clean up and warnings fix
* more warnings
* white space
* new blank line at the EOF removed
* HAVE_OPENCL guard
* remove unnecessary ocl API call
* remove sum test workaround
* check if opencl activated
* fix std::str warning
* CPU fall back for symm7x7
* gpu test kernel draft
* adjust have opencl guard
* more guards
* one more attempt to adjust guards
* empty stub files and kernel source files creation in the test directory
* try to force auto generation
* one more attempt to force build
* remove symm7x7 custom from gapi module
* looks like that this version works properly on Win desktop
* clean up
* more clean up
* address some suggestions from Dmitry's review
* const kernel coefficients
* CV_Error in kernel + try to fix cpu fallback
* CV_Error_ instead CV_Error
* everything in one gapi_gpu_test.cpp
* fix warning
* remove kernel generation, add kernel string
* avoid generated code and ocl internal namespace
* fix misprint
* c_str
* Added caching of agents execution sequence
* Merged linesRead() and nextWindow() methods on FluidAgent in one method
* Added caching of input lines for fluid::View
* Added caching of output lines for fluid::Buffer
* Fixed GAPI_Assert to work in standalone mode
G-API: Doxygen class reference
* G-API Doxygen documentation: covered cv::GComputation
* G-API Doxygen documentation: added sections on compile arguments
* G-API Doxygen documentation: restructuring & more text
* Added new sections (organized API reference into it);
* Documented GCompiled, compile args, backends, etc.
* G-API Doxygen documentation: documented GKernelPackage and added group for meta
* G-API: First steps with tutorial
* G-API Tutorial: First iteration
* G-API port of anisotropic image segmentation tutorial;
* Currently works via OpenCV only;
* Some new kernels have been required.
* G-API Tutorial: added chapters on execution code, inspection, and profiling
* G-API Tutorial: make Fluid kernel headers public
For some reason, these headers were not moved to the public
headers subtree during the initial development. Somehow it even
worked for the existing workloads.
* G-API Tutorial: Fix a couple of issues found during the work
* Introduced Phase & Sqrt kernels, OCV & Fluid versions
* Extended GKernelPackage to allow kernel removal & policies on include()
All the above stuff needs to be tested, tests will be added later
* G-API Tutorial: added chapter on running Fluid backend
* G-API Tutorial: fix a number of issues in the text
* G-API Tutorial - some final updates
- Fixed post-merge issues after Sobel kernel renaming;
- Simplified G-API code a little bit;
- Put a conclusion note in text.
* G-API Tutorial - fix build issues in test/perf targets
Public headers were refactored but tests suites were not updated in time
* G-API Tutorial: Added tests & reference docs on new kernels
* Phase
* Sqrt
* G-API Tutorial: added link to the tutorial from the main module doc
* G-API Tutorial: Added tests on new GKernelPackage functionality
* G-API Tutorial: Extended InRange tests to cover 32F
* G-API Tutorial: Misc fixes
* Avoid building examples when gapi module is not there
* Added a volatile API disclaimer to G-API root documentation page
* G-API Tutorial: Fix perf tests build issue
This change came from master where Fluid kernels are still used
incorrectly.
* G-API Tutorial: Fixed channels support in Sqrt/Phase fluid kernels
Extended tests to cover this case
* G-API Tutorial: Fix text problems found on team review
