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

David Geldreich	6a4bfc0863	Stream default to Stream::Null() when no default in function prototype this corrects bug #16592 where a Stream is created at each GpuMat::load(arr,stream) call a correct solution would have been to add a default to GpuMat::load but due to circular dependence between Stream and GpuMat, this is not possible add test_cuda_upload_download_stream to test_cuda.py	4 years ago
CSBVision	ec32061f5f	Update __init__.py to support symbolic links Currently, the LOADER_DIR is set as os.path.dirname(os.path.abspath(__file__)). This does not point to the true library path if the cv2 folder is symlinked into the Python package directory such that importing cv2 under Python fails. The proposed change only resolves symbolic links correctly by calling os.path.realpath(__file__) first and does not change anything if __file__ contains no symbolic link.	4 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
