8d22ac200f core: workaround flipHoriz() alignment issues 2019-12-19 00:05:23 +00:00

ed7e4273cd Merge pull request #15555 from ChipKerchner:flipVectorize 
* Vectorize flipHoriz and flipVert functions.

* Change v_load_mirror_1 to use vec_revb for VSX

* Only use vec_revb in ISA3.0

* Removing vec_revb code since some of the older compilers don't fully support it.

* Use new v_reverse intrinsic and cleanup code.

* Ensure there are no alignment issues with copies

Merge pull request #14162 from alalek:eliminate_coverity_scan_issues 
core: eliminate coverity scan issues (#14162)

* core(hal): avoid using of r,g,b,a parameters in interleave/deinterleave

- static analysis tools blame on possible parameters reordering
- align AVX parameters with corresponding SSE/NEO/VSX/cpp code

* core: avoid "i,j" parameters in Matx methods

- static analysis tools blame on possible parameters reordering

* core: resolve coverity scan issues

c8e6ce304f Catch exceptions by const-reference 
Exceptions caught by value incur needless cost in C++, most of them can
be caught by const-reference, especially as nearly none are actually
used. This could allow compiler generate a slightly more efficient code.

46a668c565 Add multi-channel mask support to mean, meanStdDev and setTo 
This adds the possibility to use multi-channel masks for the functions
cv::mean, cv::meanStdDev and the method Mat::setTo. The tests have now a
probability to use multi-channel masks for operations that support them.
This also includes Mat::copyTo, which supported multi-channel masks
before, but there was no test confirming this.

a57718e1ac ICV2017u3 package update; 
- 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;

14b006e808 IPP_VERSION_X100 was changed to: 
IPP_VERSION_MAJOR * 100 + IPP_VERSION_MINOR*10 + IPP_VERSION_UPDATE
to manage changes between updates more easily.

IPP_DISABLE_BLOCK was added to ease tracking of disabled IPP functions;
