C++ image processing and machine learning library with using of SIMD: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2, AVX-512, VMX(Altivec) and VSX(Power7), NEON for ARM.

Last update: Jan 5, 2023

Overview

Introduction

The Simd Library is a free open source image processing and machine learning library, designed for C and C++ programmers. It provides many useful high performance algorithms for image processing such as: pixel format conversion, image scaling and filtration, extraction of statistic information from images, motion detection, object detection (HAAR and LBP classifier cascades) and classification, neural network.

The algorithms are optimized with using of different SIMD CPU extensions. In particular the library supports following CPU extensions: SSE, SSE2, SSE3, SSSE3, SSE4.1, SSE4.2, AVX, AVX2 and AVX-512 for x86/x64, VMX(Altivec) and VSX(Power7) for PowerPC (big-endian), NEON for ARM.

The Simd Library has C API and also contains useful C++ classes and functions to facilitate access to C API. The library supports dynamic and static linking, 32-bit and 64-bit Windows, Android and Linux, MSVS, G++ and Clang compilers, MSVS project and CMake build systems.

Library folder's structure

The Simd Library has next folder's structure:

simd/src/Simd/ - contains source codes of the library.
simd/src/Test/ - contains test framework of the library.
simd/src/Use/ - contains the use examples of the library.
simd/prj/vs2013/ - contains project files of Microsoft Visual Studio 2013.
simd/prj/vs2015/ - contains project files of Microsoft Visual Studio 2015.
simd/prj/vs2017w/ - contains project files of Microsoft Visual Studio 2017 (for Windows).
simd/prj/vs2017a/ - contains project files of Microsoft Visual Studio 2017 (for Android).
simd/prj/vs2019/ - contains project files of Microsoft Visual Studio 2019.
simd/prj/cmd/ - contains additional scripts needed for building of the library in Windows.
simd/prj/cmake/ - contains files of CMake build systems.
simd/prj/sh/ - contains additional scripts needed for building of the library in Linux.
simd/prj/txt/ - contains text files needed for building of the library.
simd/data/cascade/ - contains OpenCV cascades (HAAR and LBP).
simd/data/image/ - contains image samples.
simd/data/network/ - contains examples of trained networks.
simd/docs/ - contains documentation of the library.

The library building for Windows

To build the library and test application for Windows 32/64 you need to use Microsoft Visual Studio 2019 (or 2013/2015/2017). The project files are in the directory:

simd/prj/vs2015/

By default the library is built as a DLL (Dynamic Linked Library). You also may build it as a static library. To do this you must change appropriate property (Configuration Type) of Simd project and also uncomment #define SIMD_STATIC in file:

simd/src/Simd/SimdConfig.h

Also in order to build the library you can use CMake and MinGW:

cd .\prj\cmake
cmake . -DSIMD_TOOLCHAIN="your_toolchain\bin\g++" -DSIMD_TARGET="x86_64" -DCMAKE_BUILD_TYPE="Release" -G "MinGW Makefiles"
mingw32-make

The library building for Android

To build the library and test application for Android(x86, x64, ARM, ARM64) you need to use Microsoft Visual Studio 2017. The project files are in the directory:

simd/prj/vs2017a/

By default the library is built as a SO (Dynamic Library).

The library building for Linux

To build the library and test application for Linux 32/64 you need to use CMake build systems. Files of CMake build systems are placed in the directory:

simd/prj/cmake/

The library can be built for x86/x64, PowerPC(64, big-endian) and ARM(32/64) platforms with using of G++ or Clang compilers. With using of native compiler (g++) for current platform it is simple:

cd ./prj/cmake
cmake . -DSIMD_TOOLCHAIN="" -DSIMD_TARGET=""
make

To build the library for PowerPC(64, big-endian) and ARM(32/64) platforms you can also use toolchain for cross compilation. There is an example of using for PowerPC (64 bit, big-endian):

cd ./prj/cmake
cmake . -DSIMD_TOOLCHAIN="/your_toolchain/usr/bin/powerpc-linux-gnu-g++" -DSIMD_TARGET="ppc64" -DCMAKE_BUILD_TYPE="Release"
make

For ARM (32 bit):

cd ./prj/cmake
cmake . -DSIMD_TOOLCHAIN="/your_toolchain/usr/bin/arm-linux-gnueabihf-g++" -DSIMD_TARGET="arm" -DCMAKE_BUILD_TYPE="Release"
make

And for ARM (64 bit):

cd ./prj/cmake
cmake . -DSIMD_TOOLCHAIN="/your_toolchain/usr/bin/aarch64-linux-gnu-g++" -DSIMD_TARGET="aarch64" -DCMAKE_BUILD_TYPE="Release"
make

As result the library and the test application will be built in the current directory.

The library using

If you use the library from C code you must include:

#include "Simd/SimdLib.h"

And to use the library from C++ code you must include:

#include "Simd/SimdLib.hpp"

In order to use Simd::Detection you must include:

#include "Simd/SimdDetection.hpp"

In order to use Simd::Neural you must include:

#include "Simd/SimdNeural.hpp"

In order to use Simd::Motion you must include:

#include "Simd/SimdMotion.hpp"

Interaction with OpenCV

If you need use mutual conversion between Simd and OpenCV types you just have to define macro SIMD_OPENCV_ENABLE before including of Simd headers:

#include <opencv2/core/core.hpp>
#define SIMD_OPENCV_ENABLE
#include "Simd/SimdLib.hpp"

And you can convert next types:

cv::Point, cv::Size <--> Simd::Point.
cv::Rect <--> Simd::Rectangle.
cv::Mat <--> Simd::View.

Test Framework

The test suite is needed for testing of correctness of work of the library and also for its performance testing. There is a set of tests for every function from API of the library. There is an example of test application using:

./Test -m=a -tt=1 -f=Sobel -ot=log.txt

Where next parameters were used:

-m=a - a auto checking mode which includes performance testing (only for library built in Release mode). In this case different implementations of each functions will be compared between themselves (for example a scalar implementation and implementations with using of different SIMD instructions such as SSE2, AVX2, and other). Also it can be -m=c (creation of test data for cross-platform testing), -m=v (cross-platform testing with using of early prepared test data) and -m=s (running of special tests).
-tt=1 - a number of test threads.
-fi=Sobel - an include filter. In current case will be tested only functions which contain word 'Sobel' in their names. If you miss this parameter then full testing will be performed. You can use several filters - function name has to satisfy at least one of them.
-ot=log.txt - a file name with test report (in TEXT file format). The test's report also will be output to console.

Also you can use parameters:

-help or -? in order to print help message.
-r=../.. to set project root directory.
-pa=1 to print alignment statistics.
-c=512 a number of channels in test image for performance testing.
-h=1080 a height of test image for performance testing.
-w=1920 a width of test image for performance testing.
-oh=log.html - a file name with test report (in HTML file format).
-s=sample.avi a video source (See Simd::Motion test).
-o=output.avi an annotated video output (See Simd::Motion test).
-wt=1 a thread number used to parallelize algorithms.
-fe=Abs an exclude filter to exclude some tests.
-mt=100 a minimal test execution time (in milliseconds).
-lc=1 to litter CPU cache between test runs.

Comments

Test.exe crashes

I'm looking forward trying SIMD library for video conversions, so installed simd.4.2.73.zip, VS2017, Windows SDK 8.1, loaded the vs2017w project file, selected x64 & release and hit Build. This ran successfully, be it rather slow (never used VS so have no reference) and it looks like all files are made. I have not actually used the dll but did try Test.exe and notice it crashes after the 4th line. I also tried running "Test -m=a -tt=1 -f=Sobel -ot=log.txt" which gives me an error that Sobel is not found, and without that filter it also crashes after a few lines. I'm now left wondering if I made an error building the library. Windows 7/64.

SimdYuv420pToBgr with different YUV & RGB image sizes

Hi!

Still loving this library, it is really impressive coding..

I need to display YUV420P images as thumbnails on screen, which means they need to be converted to RGB and resized. Because this is HD video, speed is essential. Currently I first resize each of the YUV planes, and then convert to RGB. However this means an additional memory write of the (smaller) YUV image. This can be avoiding by dropping the demand that for SimdYuv420pToBgr both images must have same size. Can this be added? As speed is important, a simple pixel drop can be used (although if it can be added efficiently, a basic (bi)lineair interpolation would be great).

Thanks for considering.

Premultiplication & vice versa

Very happy with the added alpha support, your code is much faster than my "SIMD" attempts :)

I would very much like a function to convert a BGRA bitmap to premultiplied and vice versa. This would complete the alpha support in Simd.

PS: To convert a straight alpha color value bitmap to premultiplied format, multiply its R, G, and B values by A. To convert premultiplied to straight, divide R, G, and B by A. Keep in mind alpha can be 0, and values can never exceed 255.

MSVC, Intel, GCC and MinGW are fine with this, although. What could be the reason and it is possible to fix it for Clang?

Object Measurement

The SIMD library is great, but I'm not shure how I do some object measurement (e.g. finding the centre point of an object). Maybe you could list me just the functions to use: This would be very helpful.

Cmake fails with SimdVersion.h

After fighting through making cmake work on MinGw, I gradually come to understand how this all works, with this thread being the golden helper: https://github.com/glfw/glfw/issues/843#issuecomment-250316815

Whilst I can compile without MSYS only using the stock MinGW install, I'm interested in getting it to work with "Msys Makefiles" or "Unix Makefiles" I always end up with: Skip updating of file ""C:/Users/Bonfire/Desktop/winVAI/Projects/suite/pkg/Simd/prj/cmake/../..\src\Simd\SimdVersion.h"" because there are not any changes.

Everything else seems to work, make -j8 posts many compiled files, but it always files at this one: /SimdLib.cpp: In function 'const char* SimdVersion()': C:/Users/Bonfire/Desktop/winVAI/Projects/suite/pkg/Simd/src/Simd/SimdLib.cpp:79:12: error: 'SIMD_VERSION' was not declared in this scope return SIMD_VERSION; ^~~~~~~~~~~~

Is there a way to fix this?

Bug in SimdResizeMethodNearest resizer

Calling SimdResizerRunwith SimdResizeMethodNearestgives spill on the right of the resized image. E.g. if I have two YUV420P images of 1920*1080 and copy one to the first quadrant of the other (0, 0, 960, 540), there is spill to the right. See image. This does not happen with SimdResizeMethodAreaor SimdResizeMethodBilinear(did not try others) but (very!) unfortunately they are too slow. SimdLib v4.9.111. Windows 64

What could be the issue in my code?

In the SimdGaussianBlurInit() function, what is the relationship between radius and standard sigma value for Gaussian kernel?

For instance with scipy.ndimage.gaussian_filter, it gives:

img:
 [[ 0  1  2  3  4  5  6  7  8  9 10 11]
 [12 13 14 15 16 17 18 19 20 21 22 23]

 [84 85 86 87 88 89 90 91 92 93 94 95]]
img_blur (sigma=5.0):
 [[39 39 39 40 40 41 41 42 42 43 43 43]

 [62 62 63 64 65 66 66 67 68 69 70 70]
 [66 66 67 68 69 70 70 71 72 73 74 74]]

Finally, why the radius parameter in SimdGaussianBlurInit() is a const float pointer? Looks like there is no need to have a pointer for this, unless to support different radius values for X and Y axes?

Supporting multi-byte grayscale PNG images?

HI there,

So I'm trying out the current framework. After discovering Simd only supports PNG's lossless file-format, I converted my images accordingly. My input PNG's are 16-bit grayscale pixels.

So, the Framework's API is able to decode and read in my image file, but it has a funny output, according to gdb:

$1 = {width = 1124, height = 1364, stride = 4512, format = Simd::ViewSimd::Allocator::Rgba32, data = 0x555569994a00 "", _owner = true}

The output in bold was unexpected. I was hoping the View would be set to ::Int16 and the stride would be 1124*2 = 2248 So, am I to understand that my 16-bit grayscale image is now RGB, with A channels?

Is there a plan to support the pure, multi-byte grayscale pixel plane in the near-future?
If not, I'd be happy to add this in.

Thanks, Charles.

Suppress the inner bounding boxes which is contained with in bigger bounding Box.

Hello, Is there any parameter that can suppress the inner bounding box and display only the outer one? Secondly is there any document that can help in understanding the algorithms used for different part in implementation ?

Thank You.

SimdYuv420pSaveAsJpegToMemory

I'm very impressed by SimdYuv420pSaveAsJpegToMemorybut there is a problem with the colour space conversion. If I go from YUV420P to JPEG and back, the images look washed. Is there a colour space mismatch or is this caused by JPEG compression?

Also please note when choosing SimdPixelFormatNoneI get BGR, not YUV420P.

SimdYuva444pToBgraV2

I'm interested in SimdYuva444pToBgraV2. I currently create a reduced size of an YUV420P by first converting to YUV444P, resize it and then use SimdYuv444pToBgraV2to display. However if the original is YUVA420P, I currently don't see an efficient way to end up with reduced size BGRA.

Thanks.
