[G-API]: Performance tests for fitLine and findContours
* Perf.Test for findContours(H)
* Perf.Test for fitLine(2D.3D;Mat,vector<Point2i/2f/2d/3i/3f/3d>)
* Reducing the template specializations number
* Applying comments
Conv1D and Pool1D for CUDA backend
* CUDA-independent changes
* Add Conv1D and Pool1D for CUDA backend
* CUDA-independent changes
* Fix typo
* fix comment
* Update fix
* make changes more correct for pooling layer
* Minor fixes for review
* Split skip blocks
* [ts][summary.py] Extend `-o` to support tabs separated output.
* [ts][summary.py] Improve TABS sepatated output.
There is no need to print TAB at the beginning and at the end of each
row in the table.
Cosmetic change: using python list comprehension instead of for loop
to process a single row.
- migrate GStreamer backed
- migrate FFmpeg backend (with switch on legacy API)
- cv_videoio_capture_retrieve_cb_t uses Mat type instead of number of channels
[G-API]: Performance tests for boundingRect
* Update boundingRect() tests with the changes from fitLine() PR
* Add performance tests for boundingRect
* Applying comment about g_type_of_t
* Addressing comments
* Addressing comment: replace cmp_f by CompareF in perf.tests + add the default constructor for CompareF
* Fix typo
G-API: Support GFrame for ONNX infer
* Added GFrame for ONNX
* Cut test
* Removed IE from assert
* Review comments
* Added const/bbot rstrt
* View instead unique_ptr in func. sig.
* Added extractMat function, ONNXCompiled contains exMat - cv::Mat with non processed input data
* Added meta check for inferList2
* implements https://github.com/opencv/opencv/issues/19147
* CAUTION: this PR will only functions safely in the
4+ branches that already include PR 19029
* CAUTION: this PR requires thread-safe startup of the alloc.cpp
translation unit as implemented in PR 19029
