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

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

MYLS	df5a7c8ee9	build again for OpenCL. I could not find the cause of the error: ``` C:\builds_ocv\precommit_opencl\opencv\modules\ts\src\ts_perf.cpp(361): error: The difference between expect_max and actual_max is 8445966.0000002384, which exceeds eps, where expect_max evaluates to 0.9999997615814209, actual_max evaluates to 8445967, and eps evaluates to 1.0000000000000001e-005. Argument "dst0" has unexpected maximal value ``` Hope this is a false alarm.	9 years ago

MYLS	7c92ee2e6e	Split `cvWriteRawData_Base64` into three functions The three new functions: ```cpp void cvStartWriteRawData_Base64(::CvFileStorage * fs, const char* name, int len, const char* dt); void cvWriteRawData_Base64(::CvFileStorage * fs, const void* _data, int len); void cvEndWriteRawData_Base64(::CvFileStorage * fs); ``` Test is also updated. (And it's remarkable that there is a bug in `cvWriteReadData`.)	9 years ago
MYLS	29921d055d	change the parameter to `CvMat` and `CvMatND` ```cpp cvWriteMat_Base64(::cv::FileStorage & fs, ::cv::String const & name, ::cv::Mat const & mat) ``` becomes: ```cpp CV_EXPORTS void cvWriteMat_Base64(::CvFileStorage* fs, const char* name, const ::CvMat* mat); CV_EXPORTS void cvWriteMatND_Base64(::CvFileStorage* fs, const char* name, const ::CvMatND* mat); ```	9 years ago

MYLS	7b1f7c8d8e	Add Base64 support for FileStorage 1. Add Base64 support for reading and writing XML\YML file.
