[G-API]: findContours() and boundingRect() Standard Kernels Implementation
* Add findContours() standard kernel
- API and documentation provided:
- as OpenCV provides two overloads whether to calculate hierarchy or not, but they differ by only the output in sight of G-API, two different G-API functions and kernels implemented
- G-API Imgproc documentation divided into more parts according to imgproc module parts
- some typos connected with division into parts corrected
- `GArray<GArray<U>>` overload for `get_out` function provided to coonvert correctly into `vector<vector<U>>`
- OCV backend supported
- accuracy tests provided
* Add boundingRect() standard kernel
- API and documentation provided:
- GOpaque<Rect> used as an output
- as OpenCV provides two possibilities whether to take a gray-scale image or a set of 2D points (`Point2i` or `Point2f` supported), three different overloads of a single G-API function and three kernels implemented
- for a gray-scale image the overload via `GMat`
- for a set of `Point2i` - the one via GArray<`Point2i`>
- set of `Point2f` -> GArray<`Point2f`>
- OCV backend supported
- accuracy tests provided
- comparison function for Rects provided
- some typos in `gapi_tests_common` corrected
* Fix precommit windows warnings
* - Addressing comments:
- split tests
- Fix Windows warnings
* Static_cast for warnings
* - Remove randomness
- Fix unnecessary precision losses
* - Forgot reference for RNG
* addressing comments
* equalizeHist -> no group
* `const` addedin new functions
* Address suggestions:
- Hierarchical -> H
- added cv::GMatDesc::isVectorPoins()
- added support of giving a set of points to boundingRect()
* Addressing comments
- IoU comparison function added for Rects
- isPointsVector moved from a GMatDesc method to a separate function in imgproc.hpp
- enums instead of int
- typos corrected
* Addressing comments
- findContours: Point offset -> GOpaque<Point>
- removed "straight" comparison for Rects, IoU available only
- changed vectors initialization -> fix Debug test run
- Some typos
* added comment for later upgrades
* Fix not to corrupt docs by FIXME
* Addressing commens
- overload without offset added (as a temporary workaround)
- checkMetaForFindingContours -> validateFindingContoursMeta
- added ostream overload for enums used in tests
[G-API]: morphologyEx() Standard Kernel Implementation
* cv::gapi::morphologyEx() kernel
- implemented (without separate 3x3 version)
- tests added: check only different operations, not kernels/borders
* Address comments: add `const` where needed
* Replaced fundamental tyeps -> enums where needed
- added operator<< overload for cv::MorphTypes for tests output
GAPI: Addition new Color conversion kernels to CPU backend.
* Add BGR2RGB kernel to CPU backend
* Add BGR2I420 and RGB2I420 kernels to CPU backend
* Add I4202BGR and I4202RGB kernels to CPU backend
G-API: Laplacian and bilateralFilter standard kernels
* Added Laplacian kernel and tests
* Added: Laplacian kernel, Bilateral kernel (CPU, GPU); Performance and accuracy tests for this kernels
* Changed tolerance for GPU test
* boner
* Some changes with alignment; Tests's parameters are the same as for OCV
* Cut tests
* Compressed tests
* Minor changes (rsrt bb)
* Returned types
- cv::gapi::goodFeaturesToTrack() kernel is implemented
- tests (for exact check with cv::goodFeaturesToTrack() and for internal cases) are implemented
- a custom comparison function for vectors and a custom test fixture implemented
- some posiible issues as wrong/inexact sorting of two compared vectors are
not taken into account
- initializations of an input Mat using a picture from opencv_extra implemented (function from gapi_streaming_test used)
> Size parameter is changed from int to cv::Size type to allow rectangle kernels
> Kernel creation code is adopted for different kernel sizes to not create only white images on the output
