Piotr Kubaj	68e425f869	Add support for runtime CPU feature check on POWER on FreeBSD. 1. Code uses PPC_FEATURE_HAS_VSX, but it's not checked similarly to PPC_FEATURE2_ARCH_3_00 and PPC_FEATURE2_ARCH_3_00 for availability. FreeBSD has those macros in machine/cpu.h, but I went with the way chosen for PPC_FEATURE2_ARCH_3_00 and PPC_FEATURE2_ARCH_3_00. Other than that, FreeBSD also has sys/auxv.h and that's where elf_aux_info() is defined. 2. getauxval() is actually Linux-only, but code checked for __unix__. It won't work on all UNIX, so change it back to __linux__. Add another code variant strictly for FreeBSD. 3. Update comment. This commit adds code for FreeBSD, but recently there appeared support for powerpc64 in OpenBSD.	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
