Merge pull request #19842 from gasparitiago:3.4
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

the test_imgproc accuracy requirements on that test and fix indentation on
the latter.

* 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

c1cdb2416a imgproc(resize): improve 8u3 HResize vector exit calc
Actually, we can do this in constant time. xofs always
contains same or increasing offset values. We can instead
find the most extreme value used and never attempt to load it.

Similarly, we can note for all dx >= 0 and dx < (dwidth - cn)
where xofs[dx] + cn < xofs[dwidth-cn] implies dx < (dwidth - cn).

Thus, we can use this to control our loop termination optimally.

This fixes #16137 with little or no performance impact. I have
also added a debug check as a sanity check.

* Handle det == 0 in findCircle3pts.

Issue 16051 shows a case where findCircle3pts returns NaN for the
center coordinates and radius due to dividing by a determinant of 0. In
this case, the points are colinear, so the longest distance between any
2 points is the diameter of the minimum enclosing circle.

* imgproc: Prevent 1B overrun of 8C3 SIMD optimization

The fourth value read via v_load_q is essentially ignored,
but can cause trouble if it happens to cross page boundaries.

The final few iterations may attempt to read the most extreme
elements of S, which will read 1B beyond the array in most
aligment cases. Dynamically compute the stop. This could be
hoised from the loop, but will require a more extensive change.

Likewise, cleanup the iteration increment statements to make
it more obvious they do channel count (3) elements per pass.

This should resolve #16137

* resize: HResizeLinear reduce duplicate work

There appears to be a 2x unroll of the HResizeLinear against k,
however the k value is only incremented by 1 during the unroll. This
results in k - 1 duplicate passes when k > 1.

Likewise, the final pass may not respect the work done by the vector
loop. Start it with the offset returned by the vector op if
implemented. Note, no vector ops are implemented today.

The performance is most noticable on a linear downscale. A set of
performance tests are added to characterize this.  The performance
improvement is 10-50% depending on the scaling.

* imgproc: vectorize HResizeLinear

Performance is mostly gated by the gather operations
for x inputs.

Likewise, provide a 2x unroll against k, this reduces the
number of alpha gathers by 1/2 for larger k.

While not a 4x improvement, it still performs substantially
better under P9 for a 1.4x improvement. P8 baseline is
1.05-1.10x due to reduced VSX instruction set.

For float types, this results in a more modest
1.2x improvement.

* Update U8 processing for non-bitexact linear resize

* core: hal: vsx: improve v_load_expand_q

With a little help, we can do this quickly without gprs on
all VSX enabled targets.

* resize: Fix cn == 3 step per feedback

Per feedback, ensure we don't overrun. This was caught via the
failure observed in Test_TensorFlow.inception_accuracy.
