I want to use the API for face tagging on doors in my company, but I noticed that upon receiving a printed photo image api returns as valid, is there any Anti-Spoofing for the API not recognizing photos on camera?

I have upgraded my SDK to 1.2.1 via nuget. But I cannot find the construction method with apiRoot arg.

I have the one with subscriptionKey only. Could you please help to take a look?
public FaceServiceClient(string subscriptionKey)

Below is the meta data I get from visual studio, which shows I am with 1.2.1.

Hi,

I would like to thank all contributors and supporters.

I was trying to build the "FaceAPI-WPF-Samples.sln" under Cognitive-Face-Windows-master\Sample-WPF location. While building it was throwing "Assembly 'SampleUserControlLibrary' was not found".
Please check the screenshot for the same.

Could you please check and upload the new version build?
Thanks in Advance!!

I subscribed to Face API using the subscription key for the trial version. But I am unable to make the rest api call as I getting the following JSON :
{
"error": {
"code": "Unspecified",
"message": "Access denied due to invalid subscription key. Make sure you are subscribed to an API you are trying to call and provide the right key."
}
}
This was tried out in face api console in API reference. The same error is seen in the c# code as well. Kindly please help

PS: I used the correct subscription key that was assigned to me for this particular app.

Microsoft.ProjectOxford.Face cant be found anymore.

I did not find any support for proxy on the client side. Any plans?

Would you consider a PR to handle temporary failures internally before throwing an exception?

Currently if a user calls Identify and the person group provided is being trained, that exception gets thrown out to the client app to handle.

Would it be worth handling this internally?
In EntityFramework they internally handle some errors and retry ref

We could do the same

Opening the solution FaceAPI-WPF-Samples.sln has two projects. Project "FaceAPI-WPF-Samples" opens fine. Project "SampleUserControlLibrary" fails to load as it is not found in the respective location.

Please check the zip file or give right steps to use.

HI，thanks for share the api for developers, but i can't use the api with the Ocp-Apim-Subscription-Key，like this ：https://westus.dev.cognitive.microsoft.com/docs/services/5639d931ca73072154c1ce89/operations/563b31ea778daf121cc3a5fa/console

Hello!
Trying to detect a face, I always get the same error. I have no clue on what I am doing wrong. When I google for this, I find nothing on the C# API.

Image too small or too big

I believe this is a bug in this client API

Some of my code:

private void DoSomething(SoftwareBitmap original, BitmapBounds bounds) 
{
	using (var inputStream = new InMemoryRandomAccessStream())
	{
		using (var converted = SoftwareBitmap.Convert(original, BitmapPixelFormat.Rgba16))
		{
			var encoder = await BitmapEncoder.CreateAsync(BitmapEncoder.PngEncoderId, inputStream);
			encoder.SetSoftwareBitmap(converted);
			// Comment this line, no difference
			encoder.BitmapTransform.Bounds = bounds;
			await encoder.FlushAsync();

			// Display the image in my window
			BitmapImage xamlImage = new BitmapImage();
			xamlImage.SetSource(inputStream);
			await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.High, () => {
			    m_FacePreviewImage.Source = xamlImage;
			});

			// ============================================================
			// Here it is!
			// ============================================================
			var client = new FaceServiceClient("______KEY___HERE______");
			Face[] guids;
			try
			{
			    guids = await client.DetectAsync(inputStream.AsStream());
			} catch (FaceAPIException er)
			{
			    Debug.WriteLine("Exception: " + er.ErrorMessage);
			    return;
			}
			// More code...
		}
	}
}

Hi,
I keep getting the error : exception of type 'Microsoft.ProjectOxford.Face.FaceApiException' was thrown.
I am using standard price tier and my code is :

Private Shared Function CreateFaceClient() As IFaceServiceClient
Return New FaceServiceClient("key", "https://eastus2.api.cognitive.microsoft.com/face/v1.0")
End Function

Private Async Sub Button4_ClickAsync(sender As Object, e As EventArgs) Handles Button4.Click
Button4.Enabled = False
Try
If CameraControl1.TakeSnapshot() Is Nothing Then
MsgBox("Take a Picture First")
Exit Sub
End If
Dim url As String = Path.Combine(My.Computer.FileSystem.SpecialDirectories.Temp, "faceapi.jpg") ' "C:\Users\Cisse\Desktop\08388022IJJSB.jpg"
CameraControl1.TakeSnapshot().Save(url, Imaging.ImageFormat.Jpeg)
Dim personGroupId As String = "1"
Dim faceServiceclient As IFaceServiceClient = CreateFaceClient()
Using fs As Stream = File.OpenRead(url)
Dim faces = Await faceServiceclient.DetectAsync(fs)
Dim faceIds = faces.Select(Function(face) face.FaceId).ToArray()
Dim results = Await faceServiceclient.IdentifyAsync(personGroupId, faceIds)
For Each identifyResult In results
' MsgBox(identifyResult.FaceId.ToString())
If identifyResult.Candidates.Length = 0 Then
MsgBox("No one identified")
Else
Dim candidateid = identifyResult.Candidates(0).PersonId
Dim person = Await faceServiceclient.GetPersonAsync(personGroupId, candidateid)
MsgBox("Welcome :" & person.Name & Space(2) & person.UserData)

                End If
            Next
        End Using
    Catch ex As Exception
        MsgBox(ex.Message)
    Finally
        Button4.Enabled = True
    End Try

End Sub

When I am showing my face using the image stored in my phone to Web Camera. It still detects as a face.. Is there any way to avoid that.. Only detect 3D Faces, not from mobile phone

Two suggestions in regards to the following error:
Access denied due to invalid subscription key. Make sure you are subscribed to an API you are trying to call and provide the right key.

1. 'Subscription key' is easily mistaken for subscription ID, service key or API key might be better.

2. The endpoint defaults to westus, and when a client is created with just the subsciption key the client will use the default endpoint. We should either not provide a default endpoint and instead require one when the client is instantiated, or at least suggest in the error message that the endpoint might be wrong

Mobile developers want to take advantage of this package, but currently cannot due to targeting issues. Because there's really nothing Windows-specific in this (we're just pushing and pulling down data from the Face SDK service), this should be retargeted to include Xamarin.iOS and Xamarin.Android.

More information here:
https://docs.microsoft.com/en-us/nuget/guides/create-cross-platform-packages

STR:

• clone https://github.com/Microsoft/Cognitive-Face-Windows.git
• open Cognitive-Face-Windows\Sample-WPF\FaceAPI-WPF-Samples.sln

I was testing the WPF to see some sample code for a Xamarin App and I could not get my API key working. I noticed the different regions you could use and I saw on the Face Detection DLL (Microsoft.ProjectOxford.Face) you have the URL hardcoded on the file FaceServiceClient.cs.

I had to recreate the service on Azure and put it on westus to get the WPF app working.

It would be nice that this parameter could be configurable from the client.

Please, merge 2 repos to avoid code copy-paste... code is 100% the same in both repos except of samples...

Hi all

I have written a PowerShell Module with a full implementation of the Microsoft Azure Face API.
As described in the contribution guidelines, I would like to offer this as a sample implementation for PowerShell.

You can review my code under the following GitHub URL:
https://github.com/MLauper/ps-AzureFaceAPI/tree/master

I appreciate any feedback on this little project.

Regards,
Marco

I have received an e-mail notification saying that the current endpoint will stop working tomorrow. I'm afraid that my application using Face API will stop working as well.

My application is using Face API through the client in this NuGet package: https://www.nuget.org/packages/Microsoft.ProjectOxford.Face/

What should I do to avoid problems with the upcoming change?

Thanks

I have an Azure service which makes use of multiple Project Oxford APIs, and overnight calls to each of the services started failing.

I looked through the logs, and found that the client libraries for both Vision and Face were throwing a System.Exception, with message: "Transport error".

Eventually, I found that invoking the APIs using rest directly, I got a useful message back, saying that the keys had expired. Why this happened is a separate issue, along with why I didn't get any emails to say that the keys were going to expire (they still show as active on the website). But that's all separate - this bug relates to the fact that the client libraries shouldn't just throw a generic Exception with such a vague message. The message returned by the rest API should be wrapped in the client-specific exception.

Copied from original issue: microsoft/ProjectOxford-ClientSDK#13

According to the README and several other sources, this library (Project Oxford) is deprecated in place of Microsoft.Azure.CognitiveServices.Vision.Face, however, the CognitiveServices SDK is labeled as a prerelease according to the NuGet package listing.

Everything appears to function as normal using this SDK, which is great, but it would be nice to get a heads up before we are required to switch over to cognitive services (the Azure SDK) entirely.

When can we expect this library to be fully removed and/or unsupported?

From @SaqibS on November 24, 2015 18:35

I am using the C# client SDKs available from NuGet.

When using the face detection API, you get back an array of FaceRectangles. However, the Emotion Detection API requires an array of Rectangles (from the Common namespace). Both types have the same 4 fields one would expect.

These should be consolidated - either FaceDetection should return Common Rectangles, or else FaceRectangle should inherit from Rectangle. Or, just use System.Drawing.Rectangle.

i got thiss error for native application Xamarin android

I am not able to build the project. Please check the error.

C:\Users\This PC\Desktop\Cognitive-Face-Windows-master\Cognitive-Common-Windows\SampleUserControlLibrary\SampleUserControlLibrary.csproj : error : The project file could not be loaded.

I was trying to use the Face API Client Library 1.4 for the detection scenario. I always get back this error: System.UriFormatException: 'Invalid URI: The format of the URI could not be determined.'

The same Uri works with no issues when using the REST endpoint.

There's a sample console of my test here: https://github.com/cesar-younes/FaceAPIclientTestConsole

As i m trying to build this project, it is showing that not able to load sampleUserControlLibrary. i am new in this field,help me regarding this

This error pops up whenever I try to run this application. The debugger points to the line of code below the line where we create a new faceserviceclient object.

Projectoxford.face.contract.face[] faces = await faceserviceclient.detectasync(fstream,false,true,new face attribute......

With a accompanying message that says
"Socket exception : an existing connection was forcibly closed by the remote host"

My internet is Preety fast

Could not install package 'Microsoft.ProjectOxford.Face 1.2.1.2'. You are trying to install this package into a project that targets 'MonoAndroid,Version=v7.0', but the package does not contain any assembly references or content files that are compatible with that framework. For more information, contact the package author. 0

Is the Face API sdk supported on .net core?

When I download the sdk with nuget, it says that the package was restored using .NET Framework 4.x.x instead of .NETCoreApp 2.0.

Does this mean it is not supported?

when I used face similar for number of images appear this error:
"An exception of type 'Microsoft.ProjectOxford.Face.FaceAPIException' occurred in mscorlib.dll but was not handled in user code".
How can I solve it?

Hello Team,

I was consuming the face in a sample Bot project.
I was able to exploit the API but after the completion of process i,e face Analysis I am getting a Error "Sorry my bot have Issue." on checking with emulator for POST.500 Error it has the following description:
An error has occurred.",\r\n "exceptionMessage": "Type 'Microsoft.Azure.CognitiveServices.Vision.Face.Models.DetectedFace' in Assembly 'Microsoft.Azure.CognitiveServices.Vision.Face, Version=0.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' is not marked as serializable.",\r\n "exceptionType": "System.Runtime.Serialization.SerializationException",\r\n

Please help me with the way around for this error.
