* test coding style
[G-API]: Relocation of operators' overloads
* Relocates overloaded operators for `cv::GMat` and `cv::GScalar` to `cv::` namespace
- adds test to check usage of operators compilation
* Add tests for all the operators
* Address comments
Bit exact gaussian blur for 16bit unsigned int
* bit-exact gaussian kernel for CV_16U
* SIMD optimization
* template GaussianBlurFixedPoint
* remove template specialization
* simd support for h3N121 uint16
* test for u16 gaussian blur
* remove unnecessary comments
* fix return type of raw()
* add typedef of native internal type in fixedpoint
* update return type of raw()
* Universal Build for Big Sur
* Refactor MacOS/iOS build to only ever build one architecture at a time + improve code readability
* Workaround for CMake issue 20989
Bit-exact Nearest Neighbor Resizing
* bit exact resizeNN
* change the value of method enum
* add bitexact-nn to ResizeExactTest
* test to compare with non-exact version
* add perf for bit-exact resizenn
* use cvFloor-equivalent
* 1/3 scaling is not stable for floating calculation
* stricter test
* bugfix: broken data in case of 6 or 12bytes elements
* bugfix: broken data in default pix_size
* stricter threshold
* use raw() for floor
* use double instead of int
* follow code reviews
* fewer cases in perf test
* center pixel convention
* Fix ONNX loading in issues opencv#17516, opencv#17531
* Add tests for Linear and Matmul layers
* Disable tests for IE versions lower than 20.4
* Skip unstable tests with OpenCL FP16 on Intel GPU
* Add correct test filtering for OpenCL FP16 tests
[GSoC] Add siamrpnpp.py
* Updated base branch with siamrpnpp.py
* Addition of Parsers
* Merged to using few ONNX files, Changes to Parsers, Links to Repo
* Deleted whitespace
* Adjusting flake8 error
* Fixes according to review
