Alexander Alekhin	fadb25baf8	imgproc(warpAffine): avoid buffer indexes overflow in SIMD code	4 years ago
Yosshi999	7495a4722f	Merge pull request #18053 from Yosshi999:bit-exact-resizeNN Bit-exact Nearest Neighbor Resizing * bit exact resizeNN * change the value of method enum * add bitexact-nn to ResizeExactTest * test to compare with non-exact version * add perf for bit-exact resizenn * use cvFloor-equivalent * 1/3 scaling is not stable for floating calculation * stricter test * bugfix: broken data in case of 6 or 12bytes elements * bugfix: broken data in default pix_size * stricter threshold * use raw() for floor * use double instead of int * follow code reviews * fewer cases in perf test * center pixel convention	4 years ago
Alexander Alekhin	be17f532e1	imgproc(resize): fix resizeNNInvoker handling of generic pixel size	5 years ago
Alexander Alekhin	3a546aa380	imgproc: revert resize changes from PR 16497	5 years ago
keeper121	d84360e7f3	Merge pull request #16497 from keeper121:master * Fix NN resize with dimentions > 4 * add test check for nn resize with channels > 4 * Change types from float to double * Del unnecessary test file. Move nn test to test_imgwarp. Add 5 channels test only.	5 years ago
Alexander Alekhin	4733a19bab	Merge pull request #16194 from alalek:fix_16192 * imgproc(test): resize(LANCZOS4) reproducer 16192 * imgproc: fix resize LANCZOS4 coefficients generation	5 years ago
Alexander Alekhin	8a3c394d6a	don't use constructors for C API structures	6 years ago
Vadim Pisarevsky	b8b7ca7302	Rewite polar transforms (#11323 ) * Rewrite polar transformations - A new wrapPolar function encapsulate both linear and semi-log remap - Destination size is a parameter or calculated automatically to keep objects size between remapping - linearPolar and logPolar has been deprecated * Fix build warning and error in accuracy test * Fix function name to warpPolar * Explicitly specify the mapping mode, so we retain all the parameters as non-optional. Introduces WarpPolarMode enum to specify the mapping mode in flags * resolves performance warning on windows build * removed duplicated logPolar and linearPolar implementations	7 years ago
Alexander Alekhin	4a297a2443	ts: refactor OpenCV tests - removed tr1 usage (dropped in C++17) - moved includes of vector/map/iostream/limits into ts.hpp - require opencv_test + anonymous namespace (added compile check) - fixed norm() usage (must be from cvtest::norm for checks) and other conflict functions - added missing license headers	7 years ago
Vitaly Tuzov	51cb56ef2c	Implementation of bit-exact resize. Internal calls to linear resize updated to use bit-exact version. (#9468 )	7 years ago
vartenkov	3fbe1f8d64	Fix multichannel warping with BORDER_CONSTANT Warping a matrix with more than 4 channels using BORDER_CONSTANT and INTER_NEAREST, INTER_CUBIC or INTER_LANCZOS4 interpolation led to undefined behaviour. This commit changes the behavior of these methods to be similar to that of INTER_LINEAR. Changed the scope of some of the variables to more local. Modified some tests to be able to detect the error described.	8 years ago
