Pavel Rojtberg	27ae1578ac	BackgroundSubtractorMOG2Impl: only use OpenCL if input image is UMat	8 years ago
Dimitrios Katsaros	41431e11f5	Imgcodecs: Implemented simple tests for PAM format	8 years ago
Dimitrios Katsaros	4e513a3346	Imgcodecs: Fixed a bug with checkSignature in GdalDecoder In cases where the signaure string contains a terminating character, the std::string member function size returns a smaller value than the allocated string. In these cases, if you then try to use substr, you will get an out_of_range exception. This patch remedies the problem.	8 years ago
Dimitrios Katsaros	6172803012	imgcodecs: Implementation of PAM encoder/decoder This patch implements the PAM image format as defined at: http://netpbm.sourceforge.net/doc/pam.html The PAM format provides a generic means for storing 2 dimensional information. This is useful for opencv since there are cases where data gets translated into non standardized formats, which makes it difficult to store and load this information.	8 years ago
Vladislav Sovrasov	dfe4519c07	Add QR decomposition to HAL	8 years ago
mschoeneck	9e61a28b2e	Improve canny (#7227 ) * Improve Canny by using _mm_movemask_epi8 to find next pixel magnitude greater than lower threshold. Added parallelized finalPass to Canny with variable gradients. Little changes in finalPass. * Some things fixed	8 years ago
Sergey Alexandrov	765dd30981	Add support for GpuMat in InputArray::isContinuous()	8 years ago
Tomoaki Teshima	903789f7af	use universal intrinsic for FP16 * use v_float16x4 (universal intrinsic) instead of raw SSE/NEON implementation * define v_load_f16/v_store_f16 since v_load can't be distinguished when short pointer passed * brush up implementation on old compiler (guard correctly) * add test for v_load_f16 and round trip conversion of v_float16x4 * fix conversion error	8 years ago

Tomoaki Teshima	7fef96be1e	add 64F intrinsic in HAL NEON * use universal intrinsic for accumulate series using float/double * accumulate, accumulateSquare, accumulateProduct and accumulateWeighted * add v_cvt_f64_high in both SSE/NEON * add test for conversion v_cvt_f64_high in test_intrin.cpp * improve some existing universal intrinsic by using new instructions in Aarch64 * add workaround for Android build in intrin_neon.hpp	8 years ago
Matthew Self	7de2e1e795	Improve perfomance of median calculation in LMedS algorithm * Use `nth_element()` to find the median instead of `sort()` in `LMeDSPointSetRegistrator::run()` * Improves performance of this part of LMedS from `n log(n)` to `n` by avoiding doing a full sort. * Makes LMedS 2x faster for 100 points, 4x faster for 5,000 points in `EstimateAffine2D()`. * LMedS is now never more than 2x slower than RANSAC and is faster in some cases.	8 years ago
Matthew Self	9678d48e1a	2-channel interleaved load/store for universal intrinsics (float only) * Added 2-channel ops to match existing 3-channel and 4-channel ops * v_load_deinterleave() and v_store_interleave() * Implements float32x4 only on SSE (but all types on NEON and CPP) * Includes tests * Will be used to vectorize 2D functions, such as estimateAffine2D()	8 years ago
mrquorr	a88bf4e5aa	test added, only if HAVE_GDCM is on	8 years ago
Vadim Pisarevsky	40b870704e	add 2 extra methods to ml::TrainData (#7169 ) * expose 2 extra methods from ml::TrainData: getNames() and getVarSymbolFlags(). The first one returns text labels from CSV (if the data has been loaded from CSV); the second one returns a matrix of boolean values; its n-th element is 1 iff the corresponding column in the CSV uses symbolic names, not numbers. * check that the dynamic_cast succeeds	8 years ago
Vadim Pisarevsky	5ddd25313f	Add Grana's connected components algorithm for 8-way connectivity. (#6823 ) * Add Grana's connected components algorithm for 8-way connectivity. That algorithm is faster than Wu's one (currently implemented in opencv). For more details see https://github.com/prittt/YACCLAB. * New functions signature and distance transform compatibility * Add tests to imgproc/test/test_connectedcomponents.cpp * Change of test_connectedcomponents.cpp for c++98 support	8 years ago

Morrison	ca318e7099	handle images with alpha better UIImages with alpha were ending up with garbage pixels in background (random memory values). Need to initialize matrix pixels before drawing UIImage with alpha on it. Note: didn’t fix Grayscale image with alpha stripping alpha in UIImage -> Mat conversion.	8 years ago
