===Change Log===
* '''The following changes requires refracting. To upgrade from 1.4.0.0 to 1.5.0.0 please see [[Emgu CV 1.5 Upgrade Instructions]]''':
+
* 4.4.0 is based on the Open CV 4.4.0 release.
** Some classes and structures are refracted, which includes:
+
* The standard license terms has been change to dual license from GPL. See it here: https://github.com/emgucv/emgucv/blob/master/LICENSE The change is to allow commercial license owners to use our regular open source build and the nuget packages from nuget.org.
*** Generic Point class, MCvPoint and MCvPoint2D32F structure becomes System.Drawing.Point and System.Drawing.PointF structure
+
* Change in nuget packages:  
*** MCvSize structure becomes System.Drawing.Size
+
** Both commercial and open source nuget package now use the Emgu.CV nuget package from nuget.org. The commercial release provide runtime nuget packages that are built with OpenVino and have IPP and CPU dispatch enabled.
*** Generic Rectangle class becomes System.Drawing.Rectangle structure.  
+
** No longer append "-CR" to commercial nuget package. Add "dldt" to nuget package compiled with openvino. This is to make clear what was in the commercial release and matches the Open CV package naming scheme (such as opencv-4.4.0-dldt-2020.4-vc16-avx2.zip). For example, the Emgu.CV.windows.runtime-CR package in v4.3 has been renamed to Emgu.CV.windows.runtime.dldt in v4.4. The Emgu.CV.windows.runtime.cuda-CR package in v4.3 has been renamed to Emgu.CV.windows.runtime.cuda.dldt in v4.4.  
*** Generic Line, LineSegment, Circle becomes its corresponding none generic structure.
+
** Added Emgu.CV.Bitmap nuget package that contains the conversion code from Emgu CV images to Bitmap. This package targets .NetStandard platform. If you are running on Linux / Mac OS platform, you will need to make sure native GDI+ is installed in your system, or it will failed on dependency when Bitmap is used.
** Managed [[OpenCV]] structures (MCv***) moved to the Emgu.CV.Structure namespace. This change requires existing code which use Managed [[OpenCV]] structures to include Emgu.CV.Structure namespace.
+
** Added Emgu.CV.UI nuget package. This package contains Emgu.CV.Platform.NetFramework.dll and Emgu.CV.Platform.NetCore.dll originally contained in Emgu.CV nuget pacakge in v4.3. These two dlls are only compatible with Windows platform.  
* Beta version of Machine Learning library wrapped in Emgu.CV.ML namespace. Machine learning algorithms wrapped includes:
+
** Emgu.CV nuget package now only targets .NetStandard platform.
** Normal Bayes Classifier
+
** Split up Emgu.CV.runtime.cuda.dnn nuget packages into 3: Emgu.CV.runtime.cuda.dnn.cnn, Emgu.CV.runtime.cuda.dnn.ops & Emgu.CV.runtime.cuda.dnn. No changes is needed on the user side, the dependency resolution will be handled automatically by nuget package manager.
** KNearest
+
* The 64-bit commercial binary for Windows is compiled with Intel Inference Engine backend v2020.4 (instead of v2020.3 in the v4.3 release)
** Support Vector Machine (SVM), thanks to Albert G.
+
* Enable IPP and CPU dispatch for windows commercial build.
** Expectation Maximization (EM)
+
* For Android runtime, in v4.3 we switched to from Open CV's custom toolchain to the android toolchain from NDK. There is a bug in Android NDK that enabled debug symbols even in release built. As a result, the Android binary is ~6 times larger. We have updated our build flags to force to exclude the debug symbols in release built. In v4.4, the android binary size are back to the v4.2 level.
** ANN_MLP (Neural Network)
+
* 4.4.0 release is build with Tesseract 4.1.1
* Support for multi-channel Matrix
+
* GPU release is build with CUDA 11.0 instead of CUDA 10
* Performance improvement for Seq<T>.ToArray() function
+
* Added Intensity Transform module
* Performance improvement for CameraCalibration class.  
+
* Added Rapid module
* Performance improvement for PlanarSubdivision class. On one of the development machine, v1.4 requires 0.6 sec to compute Delaunay's triangles for 3000 points while v1.5 needs only 0.5 sec to compute triangles for 10000 points
+
* Added eigen3 submodule to build alphamat on windows and android.
* SURF feature example uses Feature Tree to speed up the computation.
+
* Enable saliency module for Android.
* Fixed a bug in CameraCalibration.CalibrateCamera function
+
* Re-enable CudaCascadeClassifier class.
* More functions wrapped in CvInvoke class
+

 +
* Added CvInvoke.ScaleAdd function.
 +
* Added build script for Ubuntu 20.04
 +
* VideoCapture.Read function now return bool instead of void.
 +
* Updated XamarinForms.WPF to base on .NetCore instead of .Net Framework 4.7
 +
* Updated WPF demo project to base on .NetCore instead of .Net Framework 4.6.1
 +
* Change DnnInvoke.GetAvailableBackends() to property DnnInvoke.AvailableBackends
 +

===Change Log===
 
===Change Log===
* Support for [[OpenCV]] version 1.1
+
* 4.3.0 is based on the Open CV 4.3.0 release.
** Improvements in [[OpenCV]] 1.1 are automatically apply to [[Emgu CV]] 1.4.0.0. For a list of changes, please visit http://sourceforge.net/project/shownotes.php?release_id=633499
+
* For commercial release, we no longer offer binary compiled with Intel C++ compiler. In many case, Visual C++ is producing binaries as efficient as those produced with Intel C++ compiler. In certain situations (e.g. DNN modules running Facial Landmark demo), the binary produce by Visual C++ even run faster than those produced by C++ compiler. We decided to build our 64-bit commercial release without Intel C++, and instead, including Intel Inference Engine for better performance on the DNN module.
** Added ExtractSURF function in Image class; Added FeatureTree class; Added [[SURF_feature_detector_in_CSharp| SURFFeature example]] (which is a C# rewriting of the find_obj.cpp example in [[OpenCV]])
+
* The 64-bit commercial binary for Windows is compiled with Intel Inference Engine backend v2020.2. This version required a machine with AVX2 instruction set, or else it will crash when DNN module is loaded. See [[Version_History#Known_Issues | Known Issues]]. Official Open CV 4.3 release has the exact same bug from Open Vino.
** Better Homography estimation (included RANSAC and LMEDS in the wrapper)
+
* 4.3.0 release is build with Tesseract 4.1.1
* Emgu.CV.UI namespace is now in its separate assembly (instead of the Emgu.CV assembly).
+
* Mac OS binary is now signed using our developer certificate.  
* Better [[ImageBox]]
+
* Android release is now built with NDK r21. Android demo now has a minSdkVersion="24" & targetSdkVersion="29"
** [[ImageBox]] now inherits from PictureBox instead of Control. This change allow developer to easily bind Event (e.g. MouseClick event) to the [[ImageBox]] from visual studio designer.
+
* Added runtime shared project for Raspbian and Ubuntu
** Improved histogram display for multi-channel image
+
* Ubuntu and Raspbian build script now require dotnet core 3.1 instead of mono
** Applying image operation using the right-click menu is more stable. If invalid parameters are specified for some operations, error message will be displayed instead of an application crash.
+
* Enable building raspbian and Ubuntu nuget pacakge.
* Improved performance when converting 1pbbIndexed and 8bppIndexed Bitmap to Image class
+
* Removed ZedGraph dependency from Emgu.CV.UI. HistogramBox now use Open CV's plot module to draw histogram instead of using ZedGraph.
* For .bmp and .tiff (.tif) file type, the Image class constructor by default first load them as Bitmap then convert to Image. This is necessary since the [[OpenCV]] cvLoadImage function is quite buggy when loading these image formats.
+
* Removed CvBlob. It has not been updated for 7 years. Please use opencv's tracking module instead.
* More depth types are supported for both the Image class and Matrix class
+
* SIFT detector is enabled by default due patents expiration (without requirement of NONFREE build option)
* Improved PlannarSubdivision class
+
* Added Emgu.CV.UI.NetCore project which provide a .NetCore compatible implementation of Emgu.CV.UI

===Change Log===
 
===Change Log===
* Added Bgra color type
+
* 4.2.0 is based on the Open CV 4.2.0 release
* In Image class, added SByte for depth type.
+
* The Emgu.CV dll is now targeting .NetStandard 2.0 instead of .Net 3.5
* Improved [[ImageBox]] functionality
+
* The Emgu.CV.UI dll is now targeting .Net 4.6.1 instead of .Net 3.5
* Improved Histogram class
+
* '''The nuget package structures has been changed.''' Emgu.CV nuget package < 4.2.0 contains both the .Net 3.5 dll and the native dll for Windows. Starting from 4.2.0, Emgu.CV nuget package will contain only the .NetStandard 2.0 profile dll. The native dll comes in separate packages for different platforms. e.g. The Emgu.CV.runtime.windows package contains the native dll for Windows as well as the Emgu.CV.UI dll for Windows when targeting .netframework 4.6.1+. The Emgu.CV-CUDA nuget package has been replaced with Emgu.CV.runtime.windows.cuda nuget package.
* It is now possible to create Image<,> object from <I>any type</I> of Bitmap
+
* Open CV CUDA DNN module required Compute 5.3 and higher. Our cuda build not longer build with cuda compute bin option < 5.3.
* Support for reading image from ".gif" and ".exig" file
+
* Conversion between Mat, UMat, GpuMat and Image<,> and Bitmap objects requires code changes. The constructors of the Mat, UMat, GpuMat and Image<,> that accepts Bitmap has been removed. It has been added to the Emgu.CV.UI.dll file as an extension method. The dll is part of the Emgu.CV.runtime.windows (or the similar Emgu.CV.runtime.windows.cuda) nuget pacakge. Prior to v4.2.0 this code can be use to create a Mat from Bitmap <pre>Mat m = new Mat(bitmap);</pre>. In the 4.2.0 release it has to be written like this <pre>Mat m = bitmap.ToMat()</Pre> For <pre>Image<,>.Bitmap</pre> property in 4.1.x and older release, its equivalent in v4.2.0 is <pre>Image<,>.AsBitmap()</pre>
* Added MotionHistory class and Motion Detection Example
+
 
* Added EigenObjectRecognizer class for PCA base object recognition

** Note: <code>Bitmap</code> get property differs from <code>ToBitmap()</code> such that when dealing with Image&lt;Gray, Byte&gt; and Image&lt;Bgr, Byte&gt;, the image data is shared with Bitmap. Take extra caution not to use the Bitmap after the Image is disposed
+
====Enhancements====
* Performance improvement on <code>ToBitmap()</code> function. When converting Grayscale to Bitmap, use Format8bppIndexed and a custom Color Palette instead of Format24bppRgb in version 1.1.1.0. In terms of memcopy it only copy one third of data as compares with the old version. Thanks for the tips from Sebastian Kraemer.

Emgu.CV-4.4.0

Online Documentation

Change Log

  • 4.4.0 is based on the Open CV 4.4.0 release.
  • The standard license terms has been change to dual license from GPL. See it here: https://github.com/emgucv/emgucv/blob/master/LICENSE The change is to allow commercial license owners to use our regular open source build and the nuget packages from nuget.org.
  • Change in nuget packages:
    • Both commercial and open source nuget package now use the Emgu.CV nuget package from nuget.org. The commercial release provide runtime nuget packages that are built with OpenVino and have IPP and CPU dispatch enabled.
    • No longer append "-CR" to commercial nuget package. Add "dldt" to nuget package compiled with openvino. This is to make clear what was in the commercial release and matches the Open CV package naming scheme (such as opencv-4.4.0-dldt-2020.4-vc16-avx2.zip). For example, the Emgu.CV.windows.runtime-CR package in v4.3 has been renamed to Emgu.CV.windows.runtime.dldt in v4.4. The Emgu.CV.windows.runtime.cuda-CR package in v4.3 has been renamed to Emgu.CV.windows.runtime.cuda.dldt in v4.4.
    • Added Emgu.CV.Bitmap nuget package that contains the conversion code from Emgu CV images to Bitmap. This package targets .NetStandard platform. If you are running on Linux / Mac OS platform, you will need to make sure native GDI+ is installed in your system, or it will failed on dependency when Bitmap is used.
    • Added Emgu.CV.UI nuget package. This package contains Emgu.CV.Platform.NetFramework.dll and Emgu.CV.Platform.NetCore.dll originally contained in Emgu.CV nuget pacakge in v4.3. These two dlls are only compatible with Windows platform.
    • Emgu.CV nuget package now only targets .NetStandard platform.
    • Split up Emgu.CV.runtime.cuda.dnn nuget packages into 3: Emgu.CV.runtime.cuda.dnn.cnn, Emgu.CV.runtime.cuda.dnn.ops & Emgu.CV.runtime.cuda.dnn. No changes is needed on the user side, the dependency resolution will be handled automatically by nuget package manager.
  • The 64-bit commercial binary for Windows is compiled with Intel Inference Engine backend v2020.4 (instead of v2020.3 in the v4.3 release)
  • Enable IPP and CPU dispatch for windows commercial build.
  • For Android runtime, in v4.3 we switched to from Open CV's custom toolchain to the android toolchain from NDK. There is a bug in Android NDK that enabled debug symbols even in release built. As a result, the Android binary is ~6 times larger. We have updated our build flags to force to exclude the debug symbols in release built. In v4.4, the android binary size are back to the v4.2 level.
  • 4.4.0 release is build with Tesseract 4.1.1
  • GPU release is build with CUDA 11.0 instead of CUDA 10
  • Added Intensity Transform module
  • Added Rapid module
  • Added eigen3 submodule to build alphamat on windows and android.
  • Enable saliency module for Android.
  • Re-enable CudaCascadeClassifier class.
  • Enable building DynamicImage.Asp.NetCore project on Linux, Mac and Raspbian.
  • Added HelloWorld.UWP project for UWP build.
  • Added CvInvoke.ScaleAdd function.
  • Added build script for Ubuntu 20.04
  • VideoCapture.Read function now return bool instead of void.
  • Updated XamarinForms.WPF to base on .NetCore instead of .Net Framework 4.7
  • Updated WPF demo project to base on .NetCore instead of .Net Framework 4.6.1
  • Change DnnInvoke.GetAvailableBackends() to property DnnInvoke.AvailableBackends
  • Moved SIFT from XFeatures2D to Features2D namespace
  • VideoCapture.Run function use Emgu.Util.ExceptionHandler instead of System.ServiceModel.Dispatcher.ExceptionHandler.
  • The License Plate detection demo now use DNN with OpenVino model zoo for improved detection accuracy.


Enhancements

  • Implemented CI build on github.

Bug Fixes

  • This version can run on workstation without AVX2 instruction set. Fixed the known issue for Open CV 4.3 where the dldt build is not able to run on workstations without AVX2.

Dependency

  • Note that for Windows platform, this release is build with MSMF. MSMF is pre-installed for Windows 10 Home or Windows 10 Pro releases. For Windows N or certain Windows Server releases, it may require you to download and install Windows Media Feature pack. e.g. for windows server 2012 R2, following this instruction

Emgu.CV-4.3.0

Online Documentation

Browse

Change Log

  • 4.3.0 is based on the Open CV 4.3.0 release.
  • For commercial release, we no longer offer binary compiled with Intel C++ compiler. In many case, Visual C++ is producing binaries as efficient as those produced with Intel C++ compiler. In certain situations (e.g. DNN modules running Facial Landmark demo), the binary produce by Visual C++ even run faster than those produced by C++ compiler. We decided to build our 64-bit commercial release without Intel C++, and instead, including Intel Inference Engine for better performance on the DNN module.
  • The 64-bit commercial binary for Windows is compiled with Intel Inference Engine backend v2020.2. This version required a machine with AVX2 instruction set, or else it will crash when DNN module is loaded. See Known Issues. Official Open CV 4.3 release has the exact same bug from Open Vino.
  • 4.3.0 release is build with Tesseract 4.1.1
  • Mac OS binary is now signed using our developer certificate.
  • Android release is now built with NDK r21. Android demo now has a minSdkVersion="24" & targetSdkVersion="29"
  • Added runtime shared project for Raspbian and Ubuntu
  • Ubuntu and Raspbian build script now require dotnet core 3.1 instead of mono
  • Enable building raspbian and Ubuntu nuget pacakge.
  • Removed ZedGraph dependency from Emgu.CV.UI. HistogramBox now use Open CV's plot module to draw histogram instead of using ZedGraph.
  • Removed CvBlob. It has not been updated for 7 years. Please use opencv's tracking module instead.
  • SIFT detector is enabled by default due patents expiration (without requirement of NONFREE build option)
  • Added Emgu.CV.UI.NetCore project which provide a .NetCore compatible implementation of Emgu.CV.UI
  • Added Emgu.CV.Cuda.NvidiaOpticalFlow_1_0. Only support NVidia Graphic cards with Turing architecture (e.g. RTX 20xx)or above.
  • Added SetWindowProperty, GetWindowProperty & SetWindowTitle to CvInvoke. Renamed NamedWindowType to WindowFlags.
  • Added BundleAdjuster, ExposureCompensator, SeamFinder, Estimator and FeaturesMatcher for stitching.
  • Added CylindricalWarper, CylindricalWarperGpu, PlaneWarperGpu & SphericalWarperGpu for stitching.
  • Added RotationWarper for stitching.
  • Added CvInboke.EstimateChessboardSharpness
  • Added warpImage, estimateTransformation & applyTransformation function for IShapeTransformer
  • Added h/vconcate overload that accept multiple Mats.
  • Added LBPHFaceRecognizer.Histograms property.
  • Rename HoughTypes to HoughModes. Added CvEnum.HoughMode.GradientAlt.
  • Added default value for FeatherBlender's "sharpness" parameter.
  • Added "Values" property for VectorOfObject debugger visualizer, when it is not a VectorOfVector.
  • Turned HelloWorld demo from .NetFramework console app to .NetCore console app.
  • Added BuildInfo.NetCore.Console demo project.
  • Use Xamarin.Plugin.FilePicker to pick file on Xamarin Forms Windows WPF demo.
  • Use MaskRcnn with DNN module for TrafficSignRecognition demo.
  • Apply Non-maximum suppression on MaskRcnn demo.
  • Updated VideoSurveillance demo to use Tracking module instead of CvBlob.
  • Replaced WebDynamicImage demo with DynamicImage.Asp.NetCore demo.
  • Moved ShapeDetection demo to Xamarin Forms.
  • Emgu.Util.Platform can now detect iOS platform.
  • Removed lots of __IOS__ conditional compilation flags in Emgu CV source code.
  • Use .net core 3.1 for unit test.

Enhancements

  • Added Yolo demo project in Xamarin Forms.
  • Demo projects now use async function calls to download model files from Internet.
  • Xamarin forms Android demo (Face Detection, Face Landmark Detection, Mask Rcnn Detection, Stop Sign detection, Yolo) can now use Camera in real time.

Bug Fixes

  • Fixed a bug in WText Dispose function.
  • Fixed a bug in cveSuperresFrameSourceRelease PInvoke.
  • Fixed cveSuperResolutionRelease header definition.
  • Fixed a bug in QuasiDenseStereo.Process implementation.
  • Fixed the spelling on cvePlaneWarperCreate.
  • Fixed a bug in loading image file into Image<Bgr, double>.

Dependency

  • Note that for Windows platform, this release is build with MSMF. MSMF is pre-installed for Windows 10 Home or Windows 10 Pro releases. For Windows N or certain Windows Server releases, it may require you to download and install Windows Media Feature pack. e.g. for windows server 2012 R2, following this instruction

Known Issues

  • Debugger Visualizer does not work in this release. Getting debugger visualizer working for .NetStandard profile is a much challenging task than we originally thought. We will try to address that in the next release.
  • For commercial release, it is build with Intel Inference Engine backend for Windows. Due to a bug in OpenVINO, the application will crashed on Machines without AVX2 instructions sets. This bug should be fixed in OpenVINO 2020.4 according to the ticket.

Emgu.CV-4.2.0

Online Documentation

Browse

Change Log

  • 4.2.0 is based on the Open CV 4.2.0 release
  • The Emgu.CV dll is now targeting .NetStandard 2.0 instead of .Net 3.5
  • The Emgu.CV.UI dll is now targeting .Net 4.6.1 instead of .Net 3.5
  • The nuget package structures has been changed. Emgu.CV nuget package < 4.2.0 contains both the .Net 3.5 dll and the native dll for Windows. Starting from 4.2.0, Emgu.CV nuget package will contain only the .NetStandard 2.0 profile dll. The native dll comes in separate packages for different platforms. e.g. The Emgu.CV.runtime.windows package contains the native dll for Windows as well as the Emgu.CV.UI dll for Windows when targeting .netframework 4.6.1+. The Emgu.CV-CUDA nuget package has been replaced with Emgu.CV.runtime.windows.cuda nuget package.
  • Open CV CUDA DNN module required Compute 5.3 and higher. Our cuda build not longer build with cuda compute bin option < 5.3.
  • Conversion between Mat, UMat, GpuMat and Image<,> and Bitmap objects requires code changes. The constructors of the Mat, UMat, GpuMat and Image<,> that accepts Bitmap has been removed. It has been added to the Emgu.CV.UI.dll file as an extension method. The dll is part of the Emgu.CV.runtime.windows (or the similar Emgu.CV.runtime.windows.cuda) nuget pacakge. Prior to v4.2.0 this code can be use to create a Mat from Bitmap
    Mat m = new Mat(bitmap);
    . In the 4.2.0 release it has to be written like this
    Mat m = bitmap.ToMat()
    For
    Image<,>.Bitmap
    property in 4.1.x and older release, its equivalent in v4.2.0 is
    Image<,>.AsBitmap()

Enhancements

  • Added DnnSuperres module.
  • Added the turbo color map.
  • Added Vulkan and Cuda backend enumeration for DNN.
  • Added FSR Inpainting type.
  • Added Features2DToolbox.DrawMatches overload.
  • Added CvInvoke.DrawMarker

Bug Fixes

  • Fixed the ambiguous reference compilation error between 'Emgu.CV.Structure.Range' and 'System.Range' to make it compatible with the latest version of Visual Studio

Dependency

  • Note that for Windows platform, this release is build with MSMF. MSMF is pre-installed for Windows 10 Home or Windows 10 Pro releases. For Windows N or certain Windows Server releases, it may require you to download and install Windows Media Feature pack.
