Merge pull request #15214 from jumostedu:matchtemplmask
* imgproc: templmatch: Add support for mask for all methods

Add support for masked template matching. Fix/scrub old implementation
for masked matching, as it did partly not even really do a meaningful
masking, and only supported limited template matching methods.

Add documentation including formulas for masked matching.

* imgproc: test: Add tests for masked template matching

Test accuracy by comparing to naive implementation for one point.
Test compatibility/correctness by comparing results without mask and
with all ones mask.
All tests are done for all methods, all supported depths, and for 1 and
3 channels.

* imgproc: test: templmatch: Add test for crossCorr

Add a test for the crossCorr function in templmatch.cpp. crossCorr() had
to be added to exported functions to be testable.

This test can maybe help to identify the problem with template matching
on MacOSX.

* fix: Fixed wrong evaluations of the MatExpr on Clang

* fix: removed crossCorr from public interface.

If it should be exported, it should be done as separate PR.

Merge pull request #13869 from chacha21:LineVirtualIterator
* LineVirtualIterator

Proposal of LineVirtualIterator, an alternative to "LineIterator not attached to any mat".
This is basically the same implementation, replacing the address difference by a single "offset" variable. elemsize becomes irrelevant and considered to be 1. "step" is thus equal to size.width since no stride is expected.

* Update drawing.cpp

fixed warning

* improvement of LineVirtualIterator

instead of being too conservative, the new implementation gets rid of "offset/step" and only keeps a "Point currentPos" up to date.

left_to_right is renamed to forceLeftToRight as suggested (even for the old LineIterator)

assert() replaced by CV_Assert() (even for the old LineIterator)

* fixed implementation

+fixed last commit so that LineVirtualIterator gives at least the same results as LineIterator

+added a new constructor that does not require any Size, so that no clipping is done and iteration occurs from pt1 to pt2. This is done by adding a spatial offset to pt1 and pt2 so that the same implementation is used, the size being in that case the spatial size between pt1 and pt2

* Update imgproc.hpp

fixed warnings

* Update drawing.cpp

fixed whitespace

* Update drawing.cpp

trailing whitespace

* Update imgproc.hpp

+added a new constructor that takes a Rect rather than a Size. It computes the line pt1->pt2 that clips that rect.
Yet again, this is still based on the same implementation, thanks to the Size and the currentPosOffset that can artifically consider the origin of the rect at (0,0)

* revert changes

revert changes on  original LineIterator implementation, that will be superseded by the new LineVirtualIterator anyway

* added test of LineVirtualIterator

* More tests

* refactoring

Use C++11 chained constructors
Improved code style

* improve test

Added offset as random test data.

* fixed order of initialization

* merged LineIterator and VirtualLineIterator

* merged LineIterator & VirtualLineIterator

* merged LineIterator & VirtualLineIterator

* merged LineIterator & VirtualLineIterator

* made LineIterator::operator ++() more efficient

added one perfectly predictable check; in theory, since ptmode is set in the end of the constructor in the header file, the compiler can figure out that it's always true/false and eliminate the check from the inline `LineIterator::operator++()` completely

* optimized Line() function

in the most common case (CV_8UC3) eliminated the check from the loop

* improved version of HoughCircles (HOUGH_GRADIENT_ALT method)

* trying to fix build problems on Windows

* fixed typo

* * fixed warnings on Windows
* make use of param2. make it minCos2 (minimal value of squared cosine between the gradient at the pixel edge and the vector connecting it with circle center). with minCos2=0.85 we can detect some more eyes :)

* * added description of HOUGH_GRADIENT_ALT
* cleaned up the implementation; added comments, replaced built-in numeic constants with symbolic constants
* rewrote circle_popcount() to use built-in popcount() if possible
* modified some of HoughCircles tests to use method parameter instead of the built-in loop

* fixed warnings on Windows

00e8c7810f LineIterator witout a Mat (#13843)
* LineIterator witout a Mat

cv::LineIterator can be used without being attached to any cv::Mat, it only needs the size and type of data. An alternative constructor has been defined for that.
In that case, a LineIterator can no more be dereferenced with the * operator, but pos() still returns valid pixel positions.
It can be useful when LineIterator is just used to compute positions of pixels on a line, without requiring to build a Mat just for that.
Use case : with a dataset that would represent a huge image, pixel positions can be pre-computed before querying the dataset API.

* Update imgproc.hpp

removed trailing spaces

* Update drawing.cpp

fixed warning
