Vladislav Sovrasov	35a1ecef2a	core: fix infinite recursion in compare	8 years ago
Vadim Pisarevsky	4eda8efd42	resolves https://github.com/opencv/opencv/issues/7792	8 years ago
Maksim Shabunin	b04ed5956e	Fixed several issues found by static analysis in core module	8 years ago
Alexander Alekhin	4c7aa8645a	ocl: validate arguments in KernelArgs constructor - don't use undefined flag=0. It should be CONSTANT instead. - don't allow 'UMat* m=NULL' argument (except LOCAL/CONSTANT flags). This case is not handled well to provide NULL __global pointers. It is better to use '-D' macro defines instead (at least for performance)	8 years ago
Alexander Alekhin	cc09f5a7de	Merge pull request #7854 from alalek:backports_2016 (2.4) Backports from master branch (#7854)	8 years ago

Adil Ibragimov	8a4a1bb018	Several type of formal refactoring: 1. someMatrix.data -> someMatrix.prt() 2. someMatrix.data + someMatrix.step * lineIndex -> someMatrix.ptr( lineIndex ) 3. (SomeType*) someMatrix.data -> someMatrix.ptr<SomeType>() 4. someMatrix.data -> !someMatrix.empty() ( or !someMatrix.data -> someMatrix.empty() ) in logical expressions	11 years ago

Yury Gorbachev	61423a2d47	ARM NEON accelerated implementation of cv::addWeighted, cv::inRange and cv::compare functions. NOT verified on target platform, compilation passes with and without NEON.	11 years ago
Vadim Pisarevsky	5267ed46c7	1. disabled OpenCL acceleration for cv::multiply() (CV_32F), cv::divide (CV_32F), cv::convertScaleAbs (CV_32F) and cv::reduce (SUM, CV_32F), cv::reduce (MIN & MAX), cv::flip (3-channel case). 2. changed the number of test loops from 1 to 30 (except for cv::pow() test, which fails for yet unknown reason) 3. disabled IPP acceleration for 3-channel norms. 4. modified relativeNorm test function to handle very small values	11 years ago
