handle huge matrices correctly (#11505)

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

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)

332588fcee Fix bug: non-maximum suppression for hough circle
The non-maximum suppression in the Hough accumulator incorrectly ignores maxima that extend over more than one cell, i.e. two neighboring cells both have the same accumulator value. This maximum is dropped completely instead of picking at least one of the entries. This frequently results in obvious circles being missed.

The behavior is now changed to be the same as for hough_lines.

- Optimizations set change. Now IPP integrations will provide code for SSE42, AVX2 and AVX512 (SKX) CPUs only. For HW below SSE42 IPP code is disabled.
- Performance regressions fixes for IPP code paths;
- cv::boxFilter integration improvement;
- cv::filter2D integration improvement;

[GSOC] Speeding-up AKAZE, part #2 (#8951)

* feature2d: instrument more functions used in AKAZE

* rework Compute_Determinant_Hessian_Response

* this takes 84% of time of Feature_Detection
* run everything in parallel
* compute Scharr kernels just once
* compute sigma more efficiently
* allocate all matrices in evolution without zeroing

* features2d: add one bigger image to tests

* now test have images: 600x768, 900x600 and 1385x700 to cover different resolutions

* explicitly zero Lx and Ly

* add Lflow and Lstep to evolution as in original AKAZE code

* reworked computing keypoints orientation

integrated faster function from https://github.com/h2suzuki/fast_akaze

* use standard fastAtan2 instead of getAngle

* compute keypoints orientation in parallel

* fix visual studio warnings

* replace some wrapped functions with direct calls to OpenCV functions

* improved readability for people familiar with opencv
* do not same image twice in base level

* rework diffusity stencil

* use one pass stencil for diffusity from https://github.com/h2suzuki/fast_akaze
* improve locality in Create_Scale_Space

* always compute determinat od hessian and spacial derivatives

* this needs to be computed always as we need derivatives while computing descriptors
* fixed tests of AKAZE with KAZE descriptors which have been affected by this

Currently it computes all first and second order derivatives together and the determiant of the hessian. For descriptors it would be enough to compute just first order derivates, but it is not probably worth it optimize for scenario where descriptors and keypoints are computed separately, since it is already very inefficient. When computing keypoint and descriptors together it is faster to do it the current way (preserves locality).

* parallelize non linear diffusion computation

* do multiplication right in the nlp diffusity kernel

* rework kfactor computation

* get rid of sharing buffers when creating scale space pyramid, the performace impact is neglegible

* features2d: initialize TBB scheduler in perf tests

* ensures more stable output
* more reasonable profiles, since the first call of parallel_for_ is not getting big performace hit

* compute_kfactor: interleave finding of maximum and computing distance

* no need to go twice through the data

* start to use UMats in AKAZE to leverage OpenCl in the future

* fixed bug that prevented computing determinant for scale pyramid of size 1 (just the base image)
* all descriptors now support writing to uninitialized memory
* use InputArray and OutputArray for input image and descriptors, allows to make use UMAt that user passes to us

* enable use of all existing ocl paths in AKAZE

* all parts that uses ocl-enabled functions should use ocl by now

* imgproc: fix dispatching of IPP version when OCL is disabled

* when OCL is disabled IPP version should be always prefered (even when the dst is UMat)

* get rid of copy in DeterminantHessian response

* this slows CPU version considerably
* do no run in parallel when running with OCL

* store derivations as UMat in pyramid

* enables OCL path computing of determint hessian
* will allow to compute descriptors on GPU in the future

* port diffusivity to OCL

* diffusivity itself is not a blocker, but this saves us downloading and uploading derivations

* implement kernel for nonlinear scalar diffusion step

* download the pyramid from GPU just once

we don't want to downlaod matrices ad hoc from gpu when the function in AKAZE needs it. There is a HUGE mapping overhead and without shared memory support a LOT of unnecessary transfers.

This maps/downloads matrices just once.

* fix bug with uninitialized values in non linear diffusion

* this was causing spurious segfaults in stitching tests due to propagation of NaNs
* added new test, which checks for NaNs (added new debug asserts for NaNs)
* valgrind now says everything is ok

* add nonlinear diffusion step OCL implementation

* Lt in pyramid changed to UMat, it will be downlaoded from GPU along with Lx, Ly
* fix bug in pm_g2 kernel. OpenCV mangles dimensions passed to OpenCL, so we need to check for boundaries in each OCL kernel.

* port computing of determinant to OCL

* computing of determinant is not a blocker, but with this change we don't need to download all spatial derivatives to CPU, we only download determinant
* make Ldet in the pyramid UMat, download it from CPU together with the other parts of the pyramid
* add profiling macros

* fix visual studio warning

* instrument non_linear_diffusion

* remove changes I have made to TEvolution

* TEvolution is used only in KAZE now

* Revert "features2d: initialize TBB scheduler in perf tests"

This reverts commit ba81e2a711.
