Maksim Shabunin 6e9d0d9a0c Visual Studio 2015 warning and test fixes 2015-10-20 12:48:37 +03:00
Pavel Vlasov 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;
 2015-09-25 17:50:15 +03:00
Maksim Shabunin 771af4f32d Some changes to support mingw-w64 
- IPP is disabled by default when compiler is mingw (couldn't make it
work)
- fixed some warnings
- fixed some `__GNUC__` version checks (for correctness and convenience)
- removed UTF-8 BOM from hough.cpp (fixes #5253)

Scott Graybill 3d2c0ed97f Removed check on limits. A common use of HoughLines would be to restrict theta to be between a small negative number and a small positive number, e.g. -pi/16 to pi/16. This wasn't possible with the previous checks. 2015-03-13 17:04:13 -07:00
Vadim Pisarevsky be5c910358 Merge pull request #3443 from HelenWong:bug3363Fix 2014-12-02 09:14:36 +00:00
HelenWong e88bf2bc30 Updated Documentation (HoughCircles) 
Rewrite the note on HoughCircles documentation to make it more clear

Add note to clarify that the output vector of found circles is sorted by
descending order of centres accumulator values.

Also delete reductant lines on the HoughCircles documentation.

Added comments to hough circles function.

Added comments to icvhoughgradient

Misalignment in line 1183 corrected

 2014-11-07 17:52:16 +08:00
Pavel Vlasov 45958eaabc Implementation detector and selector for IPP and OpenCL; 
IPP can be switched on and off on runtime;

Optional implementation collector was added (switched off by default in CMake). Gathers data of implementation used in functions and report this info through performance TS;

TS modifications for implementations control;
