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.

38d0063c36 Do not use deprecated ReleaseCleared in protobuf library. 
This is to make code work with protobuf arenas for memory
management (ReleaseCleared is incompatible).
The cleaning of the memory is also simpler.

Update rotatedRectangleIntersection function to calculate near to origin

* Change type used in points function from RotatedRect

In the function that sets the points of a RotatedRect, the types

should be double in order to keep the precision when dealing with
RotatedRects that are defined far from the origin.

This commit solves the problem in some assertions from
rotatedRectangleIntersection when dealing with rectangles far from
origin.

* added proper type casts

* Update rotatedRectangleIntersection function to calculate near to origin

This commit changes the rotatedRectangleIntersection function in order
to calculate the intersection of two rectangles considering that they
are shifted near the coordinates origin (0, 0).

This commit solves the problem in some assertions from
rotatedRectangleIntersection when dealing with rectangles far from
origin.

* Revert type changes in types.cpp and adequate code to c++98

* Revert unnecessary casts on types.cpp

411fd2b761 Add Thickness parameter in drawMatches function 
This commit adds the feature of selecting the thickness
of the matches drawn by the drawMatches function.

In larger images, the default thickness of 1 pixel creates images
that are hard to visualize.

Merge pull request #20011 from Developer-Ecosystem-Engineering:3.4 
Improve performance on Arm64

* Improve performance on Apple silicon

This patch will
- Enable dot product intrinsics for macOS arm64 builds
- Enable for macOS arm64 builds
- Improve HAL primitives
  - reduction (sum, min, max, sad)
  - signmask
  - mul_expand
  - check_any / check_all

Results on a M1 Macbook Pro

* Updates to #20011 based on feedback

  - Removes Apple Silicon specific workarounds
  - Makes #ifdef sections smaller for v_mul_expand cases
  - Moves dot product optimization to compiler optimization check
  - Adds 4x4 matrix transpose optimization

* Remove dotprod and fix v_transpose

Based on the latest, we've removed dotprod entirely and will revisit in a future PR.

Added explicit cats with v_transpose4x4()

This should resolve all opens with this PR

* Remove commented out lines

Remove two extraneous comments

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.

This commit passes the parameter maxIters that represent
the maximum number of iterations, that can be passed to findFundamentalMat
to the method LMeDS.

This parameter were added to the function findFundamentalMat and
were passed just for the RANSAC method, but should be passed to
both methods to be consistent.
