* 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
* Fix according to review
* Addition of OpenVINO backends and Computation target devices
* Fix on backend after review
* Fixes after review
* Remove extra white space
* Removed Repeated Varaibles
* Fixed centering issue with make_cicle_pattern and make_acircle_pattern()
* Fixed issue where asymmetric circles were not at 45 degree angles. Also fixed support for inch measurement by converting parsing to usage of floating points for page size
* Fixed copy-paste error from experimental workspace
- OpenCL kernel cleanup processing is asynchronous and can be called even after forced clFinish()
- buffers are released later in asynchronous mode
- silence these false positive cases for asynchronous cleanup
* add the HH4 mode
* option to display disparity with a color map
* display current settings in the title bar
* don't close app when wanting to take screenshots
