Alexander Alekhin	acc8589083	core: clarify documentation of cv::Mat::deallocate() method	8 years ago
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

Pascal Thomet	309c962169	core/bufferpool.hpp: let msvc accept a non virtual protected destructor BufferPoolController has a non virtual protected destructor (which is legitimate) However, Visual Studio sees this as a bug, if you enable more warnings, like below ``` add_compile_options(/W3) # level 3 warnings add_compile_options(/we4265) # warning about missing virtual destructors ``` This is a proposition in order to silence this warning. See https://github.com/ivsgroup/boost_warnings_minimal_demo for a demo of the same problem with boost/exception.hpp	8 years ago

Vadim Pisarevsky	8b3d6603d5	another round of dnn optimization (#9011 ) * another round of dnn optimization: * increased malloc alignment across OpenCV from 16 to 64 bytes to make it AVX2 and even AVX-512 friendly * improved SIMD optimization of pooling layer, optimized average pooling * cleaned up convolution layer implementation * made activation layer "attacheable" to all other layers, including fully connected and addition layer. * fixed bug in the fusion algorithm: "LayerData::consumers" should not be cleared, because it desctibes the topology. * greatly optimized permutation layer, which improved SSD performance * parallelized element-wise binary/ternary/... ops (sum, prod, max) * also, added missing copyrights to many of the layer implementation files * temporarily disabled (again) the check for intermediate blobs consistency; fixed warnings from various builders	8 years ago
