Vincent Rabaud	057c3da82a	Allow Matx static function to work with Vec.	3 years ago
Vadim Levin	ccebbbc0ac	feature: submodule or a class scope for exported classes All classes are registered in the scope that corresponds to C++ namespace or exported class. Example: `cv::ml::Boost` is exported as `cv.ml.Boost` `cv::SimpleBlobDetector::Params` is exported as `cv.SimpleBlobDetector.Params` For backward compatibility all classes are registered in the global module with their mangling name containing scope information. Example: `cv::ml::Boost` has `cv.ml_Boost` alias to `cv.ml.Boost` type	3 years ago

Yuriy Chernyshov	d1b533d399	Disable -Wreturn-type-c-linkage under clang-cl clang-cl defines both __clang__ and _MSC_VER, yet uses `#pragma GCC` to disable certain diagnostics. At the time `-Wreturn-type-c-linkage` was reported by clang-cl. This PR fixes this behavior by reordering defines.	3 years ago
Vadim Levin	eca2d92791	fix: submodules creation and registration - Add special case handling when submodule has the same name as parent - `PyDict_SetItemString` doesn't steal reference, so reference count should be explicitly decremented to transfer object life-time ownership - Add sanity checks for module registration input	3 years ago

Vincent Rabaud	6b4ea68bc7	Solve Rect overflow issues. Fow now, it is possible to define valid rectangle for which some functions overflow (e.g. br(), ares() ...). This patch fixes the intersection operator so that it works with any rectangle.	3 years ago

Vadim Levin	16b9514543	feat: update conversion logic for `std::vector<T>` in Python bindings `PyObject` to `std::vector<T>` conversion logic: - If user passed Numpy Array - If array is planar and T is a primitive type (doesn't require constructor call) that matches with the element type of array, then copy element one by one with the respect of the step between array elements. If compiler is lucky (or brave enough) copy loop can be vectorized. For classes that require constructor calls this path is not possible, because we can't begin an object lifetime without hacks. - Otherwise fall-back to general case - Otherwise - execute the general case: If PyObject corresponds to Sequence protocol - iterate over the sequence elements and invoke the appropriate `pyopencv_to` function. `std::vector<T>` to `PyObject*` conversion logic: - If `std::vector<T>` is empty - return empty tuple. - If `T` has a corresponding `Mat` `DataType` than return Numpy array instance of the matching `dtype` e.g. `std::vector<cv::Rect>` is returned as `np.ndarray` of shape `Nx4` and `dtype=int`. This branch helps to optimize further evaluations in user code. - Otherwise - execute the general case: Construct a tuple of length N = `std::vector::size` and insert elements one by one. Unnecessary functions were removed and code was rearranged to allow compiler select the appropriate conversion function specialization.	3 years ago
