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.	2021-09-01 13:00:21 +03:00

Francesco Petrogalli	d29c7e7871	Merge pull request #20392 from fpetrogalli:aarch64-semihosting ... AArch64 semihosting * [ts] Disable filesystem support in the TS module. Because of this change, all the tests loading data will file, but tat least the core module can be tested with the following line: opencv_test_core --gtest_filter=-"*Core_InputOutput*:*Core_globbing.accuracy*" * [aarch64] Build OpenCV for AArch64 semihosting. This patch provide a toolchain file that allows to build the library for semihosting applications [1]. Minimal changes have been applied to the code to be able to compile with a baremetal toolchain. [1] https://developer.arm.com/documentation/100863/latest The option `CV_SEMIHOSTING` is used to guard the bits in the code that are specific to the target. To build the code: cmake ../opencv/ \ -DCMAKE_TOOLCHAIN_FILE=../opencv/platforms/semihosting/aarch64-semihosting.toolchain.cmake \ -DSEMIHOSTING_TOOLCHAIN_PATH=/path/to/baremetal-toolchain/bin/ \ -DBUILD_EXAMPLES=ON -GNinja A barematel toolchain for targeting aarch64 semihosting can be found at [2], under `aarch64-none-elf`. [2] https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-a/downloads The folder `samples/semihosting` provides two example semihosting applications. The two binaries can be executed on the host platform with: qemu-aarch64 ./bin/example_semihosting_histogram qemu-aarch64 ./bin/example_semihosting_norm Similarly, the test and perf executables of the modules can be run with: qemu-aarch64 ./bin/opecv_[test|perf]_<module> Notice that filesystem support is disabled by the toolchain file, hence some of the test that depend on filesystem support will fail. * [semihosting] Remove blank like at the end of file. [NFC] The spurious blankline was reported by https://pullrequest.opencv.org/buildbot/builders/precommit_docs/builds/31158. * [semihosting] Make the raw pixel file generation OS independent. Use the facilities provided by Cmake to generate the header file instead of a shell script, so that the build doesn't fail on systems that do not have a unix shell. * [semihosting] Rename variable for semihosting compilation. * [semihosting] Move the cmake configuration to a variable file. * [semihosting] Make the guard macro private for the core module. * [semihosting] Remove space. [NFC] * [semihosting] Improve comment with information about semihosting. [NFC] * [semihosting] Update license statement on top of sourvce file. [NFC] * [semihosting] Replace BM_SUFFIX with SEMIHOSTING_SUFFIX. [NFC] * [semihosting] Remove double space. [NFC] * [semihosting] Add some text output to the sample applications. * [semihosting] Remove duplicate entry in cmake configuration. [NFCI] * [semihosting] Replace `long` with `int` in sample apps. [NFCI] * [semihosting] Use `configure_file` to create the random pixels. [NFCI] * [semihosting][bugfix] Fix name of cmakedefine variable. * [semihosting][samples] Use CV_8UC1 for grayscale images. [NFCI] * [semihosting] Add readme file. * [semihosting] Remove blank like at the end of README. [NFC] This fixes the failure at https://pullrequest.opencv.org/buildbot/builders/precommit_docs/builds/31272.	2021-07-21 18:46:05 +03:00

HattrickGenerator	115e471515	Merge pull request #19967 from HattrickGenerator:master ... * Adding functions rbegin() and rend() functions to matrix class. This is important to be more standard compliant with C++ and an ever increasing number of people using standard algorithms for better code readability- and maintainability. The functions are copy pated from their counterparts (even though they should probably call the counterparts but this gave me some troube). They return iterators using std::reverse_iterators Follow up of an open feature request: https://github.com/opencv/opencv/issues/4641 * Fix rbegin() and rend() and provide tests for them * Removing unnecessary whitespaces * Adding rbegin and rend to Mat_ class with the right parameters so we don't need to repeat the template argument. An instantiating cv::Mat_<int> for example can call it's rbegin() function and doesn't need rbegin<int>() with this convience addition. Follows what is done for forward iterators * static cast the vector size (return size_t) to an int (that is required for opencv mat constructor) Co-authored-by: Stefan <stefan.gerl@tum.de>	2021-05-20 19:21:34 +00:00

Clement Courbet	da555a2c9b	Optimize opencv dft by vectorizing radix2 and radix3. ... This is useful for non power-of-two sizes when WITH_IPP is not an option. This shows consistent improvement over openCV benchmarks, and we measure even larger improvements on our internal workloads. For example, for 320x480, `32FC*`, we can see a ~5% improvement}, as `320=2^6*5` and `480=2^5*3*5`, so the improved radix3 version is used. `64FC*` is flat as expected, as we do not specialize the functors for `double` in this change. ``` dft::Size_MatType_FlagsType_NzeroRows::(320x480, 32FC1, 0, false) 1.239 1.153 1.07 dft::Size_MatType_FlagsType_NzeroRows::(320x480, 32FC1, 0, true) 0.991
