Add option for NMS for boxes with different labels
* DetectionModel impl
* Add option for NMS for boxes with different labels
In the detect function in modules/dnn/include/opencv2/dnn/dnn.hpp, whose implementation can be found at modules/dnn/src/model.cpp, the Non Max Suppression (NMS) is applied only for objects of the same label. Thus, a flag
was added with the purpose to allow developers to choose if they want to keep the default implementation or wether they would like NMS to be applied to all the boxes, regardless of label.
The flag is called nmsDifferentLabels, and is given a default value of false, which applies the current default implementation, thus allowing existing projects to update opencv without disruption
Solves issue opencv#18832
* Change return type of set & Add default constr
* Add assertions due to default constructor
The test has race condition, which is addressed by the patch.
The race is next:
Master thread is calling execute (effectively blocked, waiting for
callback to be called)
"Async" thread picks up the callback
Call the callback
Then sets the variables in test
After call back is called, master thread is unblocked and may check
the variables (set in point 4 by the "async" thread) earlier then they
actually changed
Changes:
callback should be called as the last step (after flag variables are
set), as it effectively unblock the master thread
fixes#18974
- explicitly declared default constructor
- made initilizer_list constructor to accept the list by copy
-- as it is more canonical (and as copying the initializer_list does
not force copy of the list items)
-- current version anyway does not do what it is intended to
- Suppressed FFMPEG + h264, h265 as it does not pass tests with CI configuration.
- Suppressed MediaFoundation backend as it always returns zero for now.
[G-API]: kmeans() Standard Kernel Implementation
* cv::gapi::kmeans kernel implementation
- 4 overloads:
- standard GMat - for any dimensionality
- GMat without bestLabels initialization
- GArray<Point2f> - for 2D
- GArray<Point3f> - for 3D
- Accuracy tests:
- for every input - 2 tests
1) without initializing. In this case, no comparison with cv::kmeans is done as kmeans uses random auto-initialization
2) with initialization
- in both cases, only 1 attempt is done as after first attempt kmeans initializes bestLabels randomly
* Addressing comments

[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

Set queue size = 1 to Copy island right after the desync.
In this case, Copy won't read more data from a "last_written"
container than required, while feeding the desynchronized path.
Sometimes Copy don't get fused into an island and behaves
on its own -- in this case, it reads more data in advance
so the slow (desync) part actually processes some data in-sync
(more than actually required)
- cv::gapi::serialize bypasses compile arguments which have no S11N specialization with serialize/deserialize callbacks for underlying types
- cv::gapi::deserialize can accept arbitraty number of serialized compile args in a stream but will return only those which are requested by user via template parameter pack if they are presented in the stream. If some or all of them are not presented cv::gapi::deserialize will ignore and return only those which are presented
- cv::gapi::deserialize can accept only types which can be deserialized (have S11N<T> specialization with the user callbacks)
- Added cv::gapi::s11n::detail::has_S11N_spec<T> trait to separate compile arguments which have S11N<T> specialization with the user callbacks
- desync() is a new (and for now, the only one) intrinsic
which splits the graph execution into asynchronous parts
when running in Streaming mode;
- desync() makes no effect when compiling in Traditional mode;
- Added tests on desync() working in various scenarios;
- Extended GStreamingExecutor to support desync(); also extended
GStreamingCompiled() with a new version of pull() returning a
vector of optional values;
- Fixed various issues with storing the type information & proper
construction callbacks for GArray<> and GOpaque;
- Introduced a new infer(Roi,GMat) overload with a sample;

Fixes two errors when building with the options WITH_CUDA=ON and BUILD_CUDA_STUBS=ON on a machine without CUDA.
In the cudaarithm module, make sure cuda_runtime.h only gets included when CUDA is installed.
In the stitching module, don't assume that cuda is present just because cudaarithm and cudawarping are present (as is the case when building with the above options).

A running GMainLoop processes many events on the GLib/GStreamer
world. While some things may work without it, many others wont.
Examples of these are signals, timers and many other source
events. The problem becomes more concerning by the fact that
some GStreamer elements rely on signals to work.
This commit allows the user to specify an OpenCV option to
start a main loop, if needed. Since the loop blocks, this is
done in a separate thread.

* refactor: remove missed macros for libavcodec and libavformat
* refactor: remove unused _opencv_ffmpeg_free function
* build: add FFMPEG libraries versions checks
- Add verbose message about what FFMPEG libraries are missing.
- Add minimal versions check set to libav 9.20 release (default ubuntu 14.04) and FFMPEG 1.1.16 release.
If the check is failed CMake produces user-friendly message instead of build error.
* fix: libavcodec version guard for AVDISCARD_NONINTRA
* fix: libav check of libavcodec version guard for AVDISCARD_NONINTRA
* fix: version check for AV_CODEC_FLAG_GLOBAL_HEADER
* fix: missing FFMPEG libraries output
[G-API]: Fluid Core kernels performance tests
* Add performance tests for a list of Fluid Core kernels
* Update gapi_core_perf_tests_fluid.cpp
Addressing a comment
- 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

* Possibility to set more than one tree for the hierarchical KMeans (default is still 1 tree).
This particularly improves NN retrieval results with binary vectors, allowing better quality
compared to LSH for similar processing time when speed is the criterium.
* Add explanations on the FLANN's hierarchical KMeans for binary data.
* Fix trees parsing behavior in hierarchical_clustering_index:
Before, when maxCheck was reached in the first descent of a tree, time was still wasted parsing
the next trees till their best leaf, just to skip the points stored there.
Now we can choose either to keep this behavior, and so we skip parsing other trees after reaching
maxCheck, or we choose to do one descent in each tree, even if in one tree we reach maxCheck.
* Apply the same change to kdtree.
As each leaf contains only 1 point (unlike hierarchical_clustering), difference is visible if trees > maxCheck
* Add the new explore_all_trees parameters to miniflann
* Adapt the FlannBasedMatcher read_write test to the additional search parameter
* Adapt java tests to the additional parameter in SearchParams
* Fix the ABI dumps failure on SearchParams interface change
* Support of ctor calling another ctor of the class is only fully supported from C+11
DNN: OpenCL/slice update

- more unique names
- inline code of copy functions
* dnn(ocl/slice): prefer to spawn more work groups
- even in case with 1D copy
- perf improvement up to 2x of kernel time (due to changed configuration 128x1x1 => 128x32x1)
* dnn(ocl/slice): cache kernel exec info
* Implement ASIFT in C++
* '>>' should be '> >' within a nested template
* add a sample for asift usage
* bugfix empty keypoints cause crash
* simpler initialization for mask
* suppress the number of lines
* correct tex document
* type casting
