Vadim Levin	390957fec4	fix: NumPy array allocation error message in vector conversion	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

Pavel Rojtberg	6c1a433c4c	python: also catch general c++ exceptions they might be thrown from third-party code (notably Ogre in the ovis module). While Linux is kind enough to print them, they cause instant termination on Windows. Arguably, they do not origin from OpenCV itself, but still this helps understanding what went wrong when calling an OpenCV function.	4 years ago

Vadim Levin	1d8c73cf6c	feature: Added `explicit` support to header parser - It is safe to remove `explicit` keyword for constructors with 1 argument, because it is C++ specific keyword and does not affect any of the generated binding.	5 years ago
Zach Lowry	0aa5391c4b	Use argument value for 'mat' in call to format for vector_mat and vector_mat_template The hard-coded string value "Mat" was used in the two format strings for vector_mat and vector_mat_template, preventing UMat arguments to functions that have these types from working correctly. as noted in #12231.	5 years ago

Vadim Levin	31289d2f32	Merge pull request #15915 from VadimLevin:dev/norm_fix Fix implicit conversion from array to scalar in python bindings * Fix wrong conversion behavior for primitive types - Introduce ArgTypeInfo namedtuple instead of plain tuple. If strict conversion parameter for type is set to true, it is handled like object argument in PyArg_ParseTupleAndKeywords and converted to concrete type with the appropriate pyopencv_to function call. - Remove deadcode and unused variables. - Fix implicit conversion from numpy array with 1 element to scalar - Fix narrowing conversion to size_t type. * Fix wrong conversion behavior for primitive types - Introduce ArgTypeInfo namedtuple instead of plain tuple.

Better handling will be added as a standalone patch * Add descriptor specialization for size_t * Add check for signed to unsigned integer conversion safety - If signed integer is positive it can be safely converted to unsigned - Add check for plain python 2 objects - Add check for numpy scalars - Add simple type_traits implementation for better code style * Resolve type "overflow" false negative in safe casting check - Move type_traits to separate header * Add copyright message to type_traits.hpp * Limit conversion scope for integral numpy types - Made canBeSafelyCasted specialized only for size_t, so type_traits header became unused and was removed. - Added clarification about descriptor pointer	5 years ago

I have tried to fix it by adding "#include <cmath>" before the line "#include <Python.h>" but then the build has failed with the error: "C:/PROGRA~1/MINGW-~1/X86_64~1.0-P/mingw64/lib/gcc/x86_64-w64-mingw32/7.2.0/include/c++/math.h:91:12:: error: 'std::_hypot' has not been declared".
