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.

ffd010767f Only use fma functions when CV_FMA3 is set. 
In practice, processors offering AVX2/AVX512 also FMA, that is why it got unnoticed.

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.

because it does not increase the reference count overall. Clarify that

taken.

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.

c8268e65fd Fix potential NaN in cv::norm. 
There can be an int overflow.
cv::norm( InputArray _src, int normType, InputArray _mask ) is fine,
not cv::norm( InputArray _src1, InputArray _src2, int normType, InputArray _mask ).

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)

This pull request is in the response to Issue  #19526. I have fixed the problem with the cube root calculation of 2*R. The Issue was in the usage of pow function with negative values of R, but if it is calculated for only positive values of R then changing x0 according to the parity of R, the Issue is resolved. Kindly consider it, Thanks!

* add cv::cubeRoot(double)

cbfd38bd41 core: rework code locality 
- to reduce binaries size of FFmpeg Windows wrapper
- MinGW linker doesn't support -ffunction-sections (used for FFmpeg Windows wrapper)
- move code to improve locality with its used dependencies
- move UMat::dot() to matmul.dispatch.cpp (Mat::dot() is already there)
- move UMat::inv() to lapack.cpp
- move UMat::mul() to arithm.cpp
- move UMat:eye() to matrix_operations.cpp (near setIdentity() implementation)
- move normalize(): convert_scale.cpp => norm.cpp
- move convertAndUnrollScalar(): arithm.cpp => copy.cpp
- move scalarToRawData(): array.cpp => copy.cpp
- move transpose(): matrix_operations.cpp => matrix_transform.cpp
- move flip(), rotate(): copy.cpp => matrix_transform.cpp (rotate90 uses flip and transpose)
- add 'OPENCV_CORE_EXCLUDE_C_API' CMake variable to exclude compilation of C-API functions from the core module
- matrix_wrap.cpp: add compile-time checks for CUDA/OpenGL calls
- the steps above allow to reduce FFmpeg wrapper size for ~1.5Mb (initial size of OpenCV part is about 3Mb)

backport is done to improve merge experience (less conflicts)

Merge pull request #19521 from zchrissirhcz:3.4-fix-core-module-android-arm64-build 
* fix core module android arm64 build

* fix core module android build when neon is off

When building for Android ARM platform, cmake with
`-D CV_DISABLE_OPTIMIZATION=ON`, the expected behavior is
not using ARM NEON, using naive computation instead.

This commit fix the un-expected compile error for neon intrinsincs.

Merge pull request #19486 from fpetrogalli:dotprod_fast-3.4 
* [hal][neon] Optimize the v_dotprod_fast intrinsics for aarch64.

On Armv8 in AArch64 execution mode, we can skip the sequence

   v<op>_<ty>(vget_high_<ty>(x), vget_high_<ty>(y))

in favour of

   v<op>_high_<ty>(x, y)

This has better changes for recent compilers to use less data movement
operations and better register allocation. See for example:

   https://godbolt.org/z/bPq7vd

* [hal][neon] Fix build failure on armv7.

* [hal][neon] Address review comments in PR.

PR: https://github.com/opencv/opencv/pull/19486

* [hal][neon] Define macro to check for the AArch64 execution state of Armv8.

* [hal][neon] Fix macro definition for AArch64.

The fix is needed to prevent warnings when building for Armv7.

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.

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.
