handle huge matrices correctly (#11505)
* make sure that the matrix with more than INT_MAX elements is marked as non-continuous, and thus all the pixel-wise functions process it correctly (i.e. row-by-row, not as a single row, where integer overflow may occur when computing the total number of elements)

Rewite polar transforms (#11323)
* Rewrite polar transformations

- A new wrapPolar function encapsulate both linear and semi-log remap
- Destination size is a parameter or calculated automatically to keep objects size between remapping
- linearPolar and logPolar has been deprecated

* Fix build warning and error in accuracy test

* Fix function name to warpPolar

* Explicitly specify the mapping mode, so we retain all the parameters as non-optional.

Introduces WarpPolarMode enum to specify the mapping mode in flags

* resolves performance warning on windows build

* removed duplicated logPolar and linearPolar implementations

592f8d8c1b Merge pull request #10232 from TomBecker-BD:hough-many-circles
Hough many circles (#10232)

* Add Hui's optimization. Merge with latest changes in OpenCV.

* Use conditional compilation instead of a runtime flag.

* Whitespace.

* Create the sequence for the nonzero edge pixels only if using that approach.

* Improve performance for finding very large numbers of circles

* Return the circles with the larger accumulator values first, as per API documentation.
Use a separate step to check distance between circles. Allows circles to be sorted by strength first. Avoids locking in EstimateRadius which was slowing it down.
Return centers only if maxRadius == 0 as per API documentation.

* Sort the circles so results are deterministic. Otherwise the order of circles with the same strength depends on parallel processing completion order.

* Add test for HoughCircles.

* Add beads test.

* Wrap the non-zero points structure in a common interface so the code can use either a vector or a matrix.

* Remove the special case for skipping the radius search if maxRadius==0.

* Add performance tests.

* Use NULL instead of nullptr.
OpenCV should compile with C++98 compiler.

* Put test suite name first.
Use different test suite names for each test to avoid an error from the test runner.

* Address build bot errors and warnings.

* Skip radius search if maxRadius < 0.

* Dynamically switch to NZPointList when it will be faster than NZPointSet.

* Fix compile error: missing 'typename' prior to dependent type name.

* Fix compile error: missing 'typename' prior to dependent type name.
This time fix it the non C++ 11 way.

* Fix compile error: no type named 'const_reference' in 'class cv::NZPointList'

* Disable ManySmallCircles tests. Failing on Mac.

* Change beads image to JPEG for smaller file size.
Try enabling the ManySmallCircles tests again.

* Remove ManySmallCircles tests. They are failing on the Mac build.

* Fix expectations to check all circles.

* Changing case on a case-insensitive file system
Step 1: remove the old file names

* Changing case on a case-insensitive file system
Step 2: add them back with the new names

* Fix cmpAccum function to be strictly weak ordered.

* Add tests for many small circles.

* imgproc(perf): fix HoughCircles tests

* imgproc(houghCircles): refactor code

- simplify NZPointList
- drop broken (de-synchronization of 'current'/'mi' fields) NZPointSet iterator
- NZPointSet iterator is replaced to direct area scan
- use SIMD intrinsics
- avoid std exceptions (build for embedded systems)

5b41599911 Fix pointPolygonTest for large coordinate values (#10222)

- move test code to test_contours.cpp, and make it C++98 compliant

* Hopefully fix compiler error by using push_back instead of emplace_back

3fbe1f8d64 Fix multichannel warping with BORDER_CONSTANT
Warping a matrix with more than 4 channels using BORDER_CONSTANT and
INTER_NEAREST, INTER_CUBIC or INTER_LANCZOS4 interpolation led to
undefined behaviour. This commit changes the behavior of these methods
to be similar to that of INTER_LINEAR. Changed the scope of some of the
variables to more local. Modified some tests to be able to detect the
error described.

b72d196753 optimization for warpAffine and warpPerspective
Add new ocl kernels for warpAffine and warpPerspective,
The average performance improvemnt is about 30%. The new
ocl kernels require CV_8UC1 format and support nearest
neighbor and bilinear interpolation.

Change contour test images to be very wide (#7464)

* Change contour test images to be very wide (#7409, #7458)

Unfortunately, slows down the tests.

* Decrease the number of contour test cases, in order to (at least partially) offset the test run duration increase caused by making the test images wider

* Don't test with very wide images on 32-bit architectures
