The following code returns a black image:

            var img = DlibDotNet.Dlib.LoadImage<RgbPixel>("mixed_faces.png");
            pictureBox1.Image = img.ToBitmap();

Can you please check?

Do you have an idea why it doesn't work?

sincerely
Niko

I'm looking for a way to train models with DlibDotNet because working in VS and WinForms is extremely convinient. Working with C++ is cumbersome and development time is long.
DlibDotNet is wonderful, very convinient and easy to operate.

Windows 10, VS 2017

I was looking for some example on how to improve an existing model (as requested here: davisking/dlib#63) or train a new model using DlibDotNet but I didn't find any.

It would be great if this could be added, perhaps with conversion of imglab tool to .NET.
I know it's a big wish, but I wanted to mention it anyway, I think it would be amazing for a lot of people.

Summary of your issue

Can not load file which contains character which are not able to represent by char*.

Environment

All environment

What did you do when you faced the problem?

When load a certain file

Example code:

var path = "images\ShinzōAbe.bmp";
var img = Dlib.LoadBmp<byte>(path);

Output:

Throw exception

What did you intend to be?

load image

I try to run the Facedetction C# example but i all the time receive an exception. all Dlls (Dlibdotnet.dll, dlibdotnet.native.dll) are in the same folder than Facedetection.dll.
I'm using dotnet core 2 with visual studio 2017 and windows 8.1

any idea ?
Thanks

Please remove, my mistake. DlibDotNet.Native.dll must not be added.

Thank You for making #32 real

compiling native dlib for dll's deployment is a trick that could be improved!
Trying to figure out how different issues occur, eg.
#50 (comment), let check that feeling of 'broken' package here?

Could You please check .nuspec https://github.com/valerysntx/DlibDotNet.NugetI propose to discuss

I read a bitmap (by opencv capture device)

capture.Read(frame);
var bmp = BitmapConverter.ToBitmap(frame);

But BitmapExtensions throws always not supported exception on:
var img = BitmapExtensions.ToArray2D<Byte>(bmp)

I use code from stackoverflow now:

   public static Array2D<Byte> ToArray2D(this Bitmap bitmap)
        {
            Int32 stride;
            Byte[] data;

            Int32 width = bitmap.Width;
            Int32 height = bitmap.Height;
            // 'using' block to properly dispose temp image.
            using (Bitmap grayImage = MakeGrayscale3(bitmap))
            {

                grayImage.UnlockBits(bits);
            }
            // Constructor is (rows, columns), so (height, width)

Hi, takuya,

  I am wondering if I could call the dlib function extract_image_4points  from DlibDotNet.
  It seemed that I could not find the function in the object browser of DlibDotNet, could 

you give me some hint on how to achieve this goal?

    Thanks!

Summary of your issue

I've compiled dlib as stated in the wiki but adding the dlls to the Assets/Plugins folder "doesn't work". I've tried DLLs with a simple C# program and works fine.

Environment

Windows 10 Anniversary
Unity 2017.4.1f1 64 bit, Microsoft Visual Studio Community 2017

Example code:

...
using DlibDotNet; // error
...

Output:

The type or namespace name 'DlibDotNet' could not be found (are you missing a using directive or an assembly reference?)

What did you intend to be?

How can I use your library with Unity3D? Probably it's my fault,

ExtractImageChips(Array2DBase, IEnumerable) leaks unmanaged memory. I use it in a realtime application every frame and end up with huge amounts of used memory that I verified to be unmanaged.

Looking at the code, I can see that Array<> does not clean up the elements (it just calls delete on the pointer). As Array<Array2D> has objects as content, I suspect this is where the memory gets leaked.

Any suggestions on how I can fix this?

Should be more simple error handling

Summary of your issue

Environment

Win 10 64bit, .Net 4.7

What did you do when you faced the problem?

Face compare too slow，after testing, the reason was that loss_metric_operator_matrixs() use a lot of time in DlibDotNet.Native.Dnn.

What did you intend to be?

Is there any way to improve execution speed?

Any plans for the DlibDotNet .nuget package /s?
Or maybe there are any motivations to ignore packaging totally,
Best Regards!

Do you have a short build guide?

I have a few problems with building it:

• class "dlib::random_cropper" has no member "get_min_object_size" [...]\DlibDotNet\src\DlibDotNet.Native\dlib\image_transforms\random_cropper.h 85
• 'dlib::random_cropper::set_min_object_size': function does not take 1 arguments[...]\dlibdotnet\src\dlibdotnet.native\dlib\image_transforms\random_cropper.h 119
• it also took me a while to figure out where to place the built dlib library
• against which version of dlib did you write your wrapper?

Another, even cooler option would be having a Nuget package.

That said/asked, it looks really well-done and I would love to use it and maybe even contribute.

Summary of your issue

Hi,

Hello!

I'm trying to use Dlib in a project with x86 Target.
I already build DlibDotNet.dll and DlibDotNet.Native.dll , but i couldn't build the DlibDotNet.Native.Dnn.dll :(

Do you have any ideia do help me?

I saw that you are using a method in BitmapExtensions to convert from Bitmaps to Array2D. This is a bit limiting and the methods you are set to be private or internal.
So I opened up the interface by adding a public method to DlibDotNet that just does this.
public static void rawToArray2D(IntPtr src, ImageTypes dstType, IntPtr dst, bool rgbReverse, uint height, uint width, uint stride, uint channels) { Dlib.Native.extensions_convert_managed_image_to_array(src, dstType.ToNativeArray2DType(), dst, rgbReverse, height, width, stride, channels); }

I think it would be nice to have this in by default as it opens a lot of possibilities to use data from many kinds of sensor and cameras easily. I'm using this with Unity3D and a Realsense D400 and it's much quicker to convert a textures and sensor data that way than with doing it manually with the external interfaces.

Summary of your issue

When loading the solution to VS 2015 it doesnt load all projects and some are unavailable
all dlibdotnet.dll references are yellow marked creating errors in code lines

Environment

Windows 10 64

What did you do when you faced the problem?

I redo everything all over again walkingthrough the wiki steps , same thing

Summary of your issue

There does not appear to be a method to set the contents of an Array2D directly (either on a per-element basis or on a bulk-basis via a byte array).

Example code:

Examples use Dlib.LoadImage<byte>() to populate Array2D objects (which loads an image from a file). There does not appear to be a safe way to set them to arbitrary byte[] arrays...

What did you intend to be?

Ideally, there would be a Dlib.LoadImageData<byte>() function which takes a byte[] as input and fills the Array2D with data.

Summary of your issue

Port https://github.com/davisking/dlib/tree/master/tools/imglab to C#

Summary of your issue

There is no function to convert DlibDotNet.Array2D to System.Windows.Media.Imaging.BitmapSource and System.Drawing.Bitmap.

Environment

Windows

What did you do when you faced the problem?

Almost developer want to treat image data in WinForms and WPF. But they can not image data from DlibDotNet.

Example code:

var array = DlibDotNet.Dlib.LoadImage<RgbPixel>("test.bmp");
var bitmap = array.ToBitmapSource();

Output:

N/A

What did you intend to be?

N/A

Summary of your issue

Hello again!
I compiled the libraries for CUDA support, and was able to run the DnnFaceRecognition fine. Using the same libraries with DnnMmodFaceDetection however, I run into an SEHException (see output below). I think I'm not the only one, since in #26, another user (postacik) mentions getting an error at this line:
var ret = Native.loss_mmod_deserialize(str, networkType);

It appears that when they got things working, they were using DnnFaceRecognition, but perhaps DnnMmodFaceDetection still had some problem?

I came upon this issue because I was using the built-in face detection/alignment through FaceRecognitionDotNet.

Environment

VS2017 (15.7.4)
CMake 3.12.3
DlibDotNet 19.15.0
Tried building CUDA libs with Dlib 19.8, 19.15, and 19.16 + CUDA 9.2.
Also tried Dlib 19.8 + CUDA 9.0.
XPS15 laptop with GTX1050

What did you do when you faced the problem?

I just tried to run the DnnFaceRecognition, DnnMmodFaceDetection, and DnnInception examples, with different combinations of CUDA/Dlib versions. Only the DnnMmodFaceDetection example kept failing.

Example code:

dotnet run --configuration Release mmod_human_face_detector.dat 2007_007763.jpg

Output:

Unhandled Exception: System.Runtime.InteropServices.SEHException: External component has thrown an exception.

What did you intend to be?

Probably some detected faces (I'm guessing). Thanks for your time!

I'm actually developing with Unity3D on Win 64. I wanna use DlibDotNet with Unity. So the idea is that I call WebcamTexture class inside of Unity for capturing image from webcam. Then, this class can return to me a Color32 Array ( a Color32 type contains 4 bytes of rgba, just like RGBAlphaPixel ). Next, i convert this color32 array into byte array by;

byte[] bytes = new byte[colors.Length * 4];
for (int i = 0; i < bytes.Length/4; i += 4)
{
bytes[i]= colors[i].r;
bytes[i+1] = colors[i].g;
bytes[i+2] = colors[i].b;
bytes[i+3] = colors[i].a;

        }

Finally, i apply this into LoadImageData function in order to recognize the number of face. (like Face Detection example) But the result is always 0.

Can you give me an idea ?

Thanks

Please provide with some list of steps on how to build the dependencies and then use the C# native version.

Hi,

I trained a object detector in python using Dlib. It detects and tracks the object successfully.
Now I would like to do the same in C#. I know that I can call the correlation tracker in C#. However, it seems that I can't call the dlib.simple_object_detector() function which accepts the trained model. Is there any alternative to this?
Also is there any implementation of the dlib fast multiclass object detection method?http://blog.dlib.net/2017/09/fast-multiclass-object-detection-in.html
More information here: http://dlib.net/train_object_detector.py.html

Thanks,

Vinícius

I try to transfer my app (facelandmark) to run on another pc than my dev machine.

Unhandled Exception: System.DllNotFoundException: Unable to load DLL 'DlibDotNet.Native.dll': Modul was not found. (Exception from HRESULT: 0x8007007E)
   at DlibDotNet.ImageWindow.Native.image_window_new()

the dlls are there? Do I need dlib dlls? or additional .NET installs?

Summary of your issue

It doesn't seem to be compatible with OpenCVSharp's face detection module.

Environment

Win10x64，OpenCVSharp 3.4.1，DlibDotNet19.15.0.20181008

What did you do when you faced the problem?

just init OpenCVSharp CascadeClassifier and init ShapePredictor(when start to load shape_predictor_68_face_landmarks.dat)

Example code:

    frontalface_cascade = new CascadeClassifier(Application.streamingAssetsPath + @"/haarcascades/haarcascade_frontalface_alt.xml");
    eye_cascade = new CascadeClassifier(Application.streamingAssetsPath + @"/haarcascades/haarcascade_eye_tree_eyeglasses.xml");//haarcascade_eye

_ShapePredictor = ShapePredictor.Deserialize(@"E:\U3Dproject\OpenCVSharp\Assets\StreamingAssets" + @"\shape_predictor_68_face_landmarks.dat");

The following code is compilable

dlib::matrix<double> mat(2, 3);
for (auto m : mat)
{
	cout << m << endl;
}

Getting the following error while doing the build:

Severity Code Description Project File Line Suppression State
Error C2039 'get_min_object_size': is not a member of 'dlib::random_cropper' DlibDotNet.Native c:\git\dlibdotnet\src\dlibdotnet.native\dlib\image_transforms\random_cropper.h 85

Error C2660 'dlib::random_cropper::set_min_object_size': function does not take 1 arguments DlibDotNet.Native c:\git\dlibdotnet\src\dlibdotnet.native\dlib\image_transforms\random_cropper.h 119

Any idea how to solve this issue?

I try using DlibDotNet.Extensions under .NET Standard 2.0 for BitmapExtensions, however the project doesn't build because WriteableBitmap is not available when running .NET Standard 2.0. Does anyone know any workarounds for this issue?
Thanks for DlibDotNet, it's a great piece of software 👍

The following code are equivalent.

dlib::matrix<double, 0, 0> m;
dlib::matrix_op<op_heatmap<dlib::matrix<double, 0, 0>>> heat = dlib::heatmap(m);

dlib::matrix<double, 0, 0> m;
dlib::matrix<double, 0, 0> heat = dlib::heatmap(m);

Therefore, MatrixOp Dlib.Heatmap(MatrixBase image) should be equivalent to Matrix Dlib.Heatmap(Matrix image)

Hey guys, how's doing?

Well, I'm wondering if is possible to use other libraries to deal with math instead of DlibDotNet related.

E.g: can I use Matrix from MathDotNet library instead of using DlibDotNet's Matrix<TElement>

Any direction on how to do it?

Thanks!

When trying to build dlibdotnet on VS 2015 i got many errors (both cmd and vs).
Any suggestions on how I can fix this?

I downloaded the latest master branch and tried to generate build files with CUDA support.

Below you can find the output of the cmake command:

https://pastebin.com/ifjik7wX

Can you please tell me what the problem may be?

I can successfully generate build files without CUDA support.

Hi,

After following your instructions on how to build the DlibDotNet.Native, I have encountered the following error:

"C:\Users\User_Lab\Desktop\HFACE\DlibDotNet-master\src\DlibDotNet.Native\build\ALL_BUILD.vcxproj" (default target) (1) -> "C:\Users\User_Lab\Desktop\HFACE\DlibDotNet-master\src\DlibDotNet.Native\build\DlibDotNet.Native.vcxproj" (default targ et) (3) -> (Link target) -> LINK : fatal error LNK1104: cannot open file 'C:\Users\User_Lab\Desktop\HFACE\dlib-19.7\examples\build\dlib_build\Rel ease\dlib.lib' [C:\Users\User_Lab\Desktop\HFACE\DlibDotNet-master\src\DlibDotNet.Native\build\DlibDotNet.Native.vcxproj ]
I'm using Visual Studio 2017, DLIB 19.7, giflib-5.1.4, cmake 3.11 on windows 10.

Any help?
Thanks

Hi,
I could not find face recognition related functions in the library. Can you explain how these can be included in DlibDotNet.Native.dll?

Thanks :)

Summary of your issue

I did everything steps by steps. I built dlibDotnet with cmake. But I'm still getting this error :

My steps result :

When trying to build DlibDotNetNative on MacOS, I get the following:

Hello, are there any examples of using the library for desctop win10 vs2017 C# FW4.6
Thank you

It seems that DlibDotNet could only load image from file ? However I want to know that if we could load image from Stream Or SoftwareBitmap ? Sometimes I need to process the camera frame in realtime.
Thanks a lot.

Hi,

Is the lib compatible with WPF applications?

Can I use it with image classes of WPF?

• Remove delete void pointer
• Point, DPoint, DRectangle and Rectangle converted to struct type
• Compile on Linux
• Change Pass-by-value to Pass-by-reference for copy object in native #lib
• Run on Linux
• Run on Mac
• Support GIF (After mod CMakeLists.txt, giflib is not available)
• Clean Native source code

Summary of your issue

FaceDetector.Operator returns duplicate result for one time call.

I encountered a problem while compile DlibDotNet.Native.Dnn, it turned out that the heap space reached os's limit while compiling the code loss_multiclass_log_per_pixel.cpp

Environment

Windows 10, 16G memory, Cmake 3.12.2 and Visual Studio 2017 Community Edition

execute the command cmake --build . --config Release under DlibDot.Native.Dnn\build directory

Summary of your issue

When I create a matrix manually using new Matrix(row, col), the TemplateColumn is 0, and there is no way to change it. When I try to compare this matrix with one generated from the FaceEncodings() method of FaceRecognitionDotNet, I get an ArgumentException. The second matrix from FaceEncodings() has TemplateColumn = 1.

I posted this in DlibDotNet instead of FaceRecognitionDotNet, since I think this has to do with the matrices themselves, and not specifically face recognition.

Environment

FaceRecognitionDotNet
DlibDotNet nuget (version 19.15.0.20180808-pre)
UWP app

What did you do when you faced the problem?

Just calculate the euclidean distance from the double[] arrays of the matrices, instead of using the subtraction operator for the matrices in the FaceDistance() method.

Example code:

        // create encoding A from saved feature vector
        public FaceEncoding(double[] array)
        {
            this._Encoding = new Matrix<double>(128, 1);
            this._Encoding.Assign(array);
        }

        // get encoding B from FaceRecognitionDotNet's FaceEncodings() method

        // try to compare the two encodings
        double faceDiff = FaceRecognition.FaceDistance(A, B);

Output:

System.ArgumentException: Value does not fall within the expected range. at DlibDotNet.Matrix`1.op_Subtraction(Matrix`1 lhs, Matrix`1 rhs)

Fails at this line: using (var diff = faceEncoding.Encoding - faceToCompare.Encoding)

I looked at the two FaceEncoding's matrices, the only difference is the TemplateColumns property. I can't set this property manually when constructing a matrix with new Matrix(row, col), but I see that Dlib might be checking this field.

            if (templateRows != matrix2.TemplateRows)
                throw new ArgumentException();
            if (templateColumns != matrix2.TemplateColumns)
                throw new ArgumentException();

What did you intend to be?

Return diff score between the two FaceEncodings.

p.s. Thanks for all your work on both DlibDotNet and FaceRecognitionDotNet!
