Rostislav Vasilikhin	4b75be801e	initial version of Lab2RGB_f tetrahedral interpolation written RGB2Lab_f added, bugs fixed, moved to float several bugs fixed LUT fixed, no switch in tetraInterpolate() temporary code; to be removed and rewritten before refactoring extra interpolations removed, some things to do left added Lab2RGB_b +XYZ version, etc. basic version is done, to be sped up tetra refactored interpolations: LUT for weights, refactor., etc. address arithm optimized initial version of vectorized code added (not compiling now) compilation fixed, now segfaults a lot of fixes, vectorization temp. disabled fixed trilinear shift size, max error dropped from 19 to 10 fixed several bugs (255 vs 256, signed vs unsigned, bIdx) minor changes packed: address arithmetics fixed shorter code experiments with pure integer calculations Lab2RGB max error decreased to 2; need to clean the code ready for vectorization; need cleaning vectorized, to be debugged precision fixed, max error is 2 Lab->XYZ shortened minor fixes Lab2RGB_f version fixed, to be completely rewritten using _b code RGB2Lab_f vectorized minors moved to separate file refactored Lab2RGB to float and int versions minor fix Lab2RGB_f vectorized minor refactoring Lab2RGBint refactored: process methods, vectorize by 4 pix Lab2RGB_f int version is done cleanup extra code code copied to color.cpp fixed blue idx bug optimizations enabled when testing; mulFracConst introduced divConst -> mulFracConst calc min time in perf instead of avg minors process() slightly sped up Lab2RGB_f: disabled int version reinterpret added, minor fixes in names some warnings fixed changes transferred to color.cpp RGB2Lab_f code (and trilinear interpolation code) moved to rgb2lab_faster whitespace shift negative fixed more warnings fixed "constant condition" warnings fixed, little speed up minor changes test_photo decolor fixed changes copied to test_lab.cpp idx bounds checking in LUT init several fixes WIP: softfloat almost integrated test_lab partially rewritten to SoftFloat color.cpp rewritten to SoftFloat test_lab.cpp: accuracy code added several fixes RGB2Lab_b testing fixed splineBuild() rewritten to SoftFloat accuracy control improved rounding fixed Luv <=> RGB: rewritten to SoftFloat OCL cvtColor Lab and Lut rewritten to SoftFloat minor fixes refactored to new SoftFloat interface round() -> cvRound, etc. fixed OCL tests softfloat.cpp: internal functions made static, unused ones removed meaningful constants extra lines removed unused function removed unfinished work it works, need to fix TODOs refactoring; more calls rewritten mulFracConst removed constants made bit exact; minors changes moved to color.cpp fixed 1 bug and 4 warnings OCL: fixed constants pow(x, _1_3f) replaced by cubeRoot(x) fixed compilation on MSVC32 magic constants explained file with internal accuracy&speed tests moved to lab_tetra branch	8 years ago

Alexander Alekhin	71517a910a	build: fix errors for MSVS2010-2013, reduce default softfloat scope	8 years ago
Rostislav Vasilikhin	c6a3a18894	SoftFloat integrated (#8668 ) * everything is put into softfloat.cpp and softfloat.hpp * WIP: try to integrate softfloat into OpenCV * extra functions removed * softfloat made stateless * CV_EXPORTS added * operators fixed * exp added, log: WIP * log32 fixed * shorter names; a lot of TODOs * log64 rewritten * cbrt32 added * minors, refactoring * "inline" -> "CV_INLINE" * cast to bool warnings fixed * several warnings fixed * fixed warning about unsigned unary minus * fixed warnings on type cast * inline -> CV_INLINE * special cases processing added (NaNs, Infs, etc.) * constants for NaN and Inf added * more macros and helper functions added * added (or fixed) tests for pow32, pow64, cbrt32 * exp-like functions fixed * minor changes * fixed random number generation for tests * tests for exp32 and exp64: values are compared to SoftFloat-based naive implementation * minor warning fix * pow(f, i) 32/64: special cases handling added * unused functions removed * refactoring is in progress (not compiling) * CV_inline added * unions {uint_t, float_t} removed * tests compilation fixed * static const members -> static methods returning const * reinterpret_cast * warning fixed * const-ness fixed * all FP calculations (even compile-time) are done in SoftFloat + minor fixes * pow(f, i) removed from interface (can cause incorrect cast) to internals of pow(f, f), tests fixed * CV_INLINE -> inline * internal constants moved to .cpp file * toInt_minMag() methods merged into toInt() methods * macros moved to .cpp file * refactoring: types renamed to softfloat and softdouble; explicit constructors, etc. * toFloat(), toDouble() -> operator float(), operator double() * removed f32/f64 prefixes from functions names * toType() methods removed, round() and trunc() functions added * minor change * minors * MSVC: warnings fixed * added int cvRound(), cvFloor, cvCeil, cvTrunc, saturate_cast<T>() * typo fixed * type cast fixed	8 years ago
