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

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
GAPI (fluid): optimization of Separable filter (#13221)
* GAPI (fluid): Separable filter: performance test
* GAPI (fluid): enable all performance tests
* GAPI: separable filters: alternative code for Sobel
* GAPI (fluid): hide unused old code for Sobel filter
* GAPI (fluid): especial code for Sobel if U8 into S16
* GAPI (fluid): back to old code for Sobel
* GAPI (fluid): run_sepfilter3x3_impl() with CPU dispatcher
* GAPI (fluid): run_sepfilter3x3_impl(): fix compiler warnings
* GAPI (fluid): new engine for separable filters (but Sobel)
* GAPI (fluid): new performance engine for Sobel
* GAPI (fluid): Sepfilters performance: fixed compilation error
* 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: 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
G-API GPU-OpenCL backend (#13008)
* gpu/ocl backend core
* accuracy tests added and adjusted + license headers
* GPU perf. tests added; almost all adjusted to pass
* all tests adjusted and passed - ready for pull request
* missing license headers
* fix warning (workaround RGB2Gray)
* fix c++ magic
* precompiled header
* white spaces
* try to fix warning and blur test
* try to fix Blur perf tests
* more alignments with the latest cpu backend
* more gapi tests refactoring + 1 more UB issue fix + more informative tolerance exceed reports
* white space fix
* try workaround for SumTest
* GAPI_EXPORTS instead CV_EXPORTS
G-API: Introduce new `reshape()` API (#12990)
* Moved initFluidUnits, initLineConsumption, calcLatency, calcSkew to separate functions
* Added Fluid::View::allocate method (moved allocation logic from constructor)
* Changed util::zip to util::indexed, utilized collectInputMeta in GFluidExecutable constructor
* Added makeReshape method to FluidExecutable
* Removed m_outputRoi from GFluidExecutable
* Added reshape feature
* Added switch of resize mapper if agent ratio was changed
* Added more TODOs and renamed a function
* G-API reshape(): add missing `override` specifiers
Fix warnings on all platforms
* Renamed Sobel operator GAPI kernel to match with OpenCV naming rules
* Fixed perf tests
* Small refactoring to check CI issue
* Refactored alignment for kernel wrappers in imgproc.hpp
Several Resize optimizations count on fetching multiple input lines at
once to do interpolation more efficiently.
At the moment, Fluid backend supports only LPI=1 for Resize kernels.
This patch introduces scheduling support for Resizes with LPI>1 and
covers these cases with new tests.
The support is initially written by Ruslan Garnov.
