WPF Face Recognition error.

Hermawan_R_ — Mon, 09 Feb 2015 06:33:01 GMT

in my code for saving the recognition file, the "nbytes" variable always return null value. but when I try to develop in winform, it runs no error. and this is the part of my code.

private void registerButton_Click(object sender, RoutedEventArgs e)
{
faceData = face.CreateOutput();
faceData.Update();
var numOfFaceDetected = faceData.QueryNumberOfDetectedFaces();
if (faceData.QueryNumberOfDetectedFaces() <= 0)
return;
PXCMFaceData.Face qface = faceData.QueryFaceByIndex(0);
if (qface == null)
{
throw new Exception("PXCMFaceData.Face null");
}
PXCMFaceData.RecognitionData rdata = qface.QueryRecognition();
if (rdata == null)
{
throw new Exception(" PXCMFaceData.RecognitionData null");
}

PXCMFaceData.RecognitionModuleData rmd = faceData.QueryRecognitionModule();
Int32 nbytes = rmd.QueryDatabaseSize();
Byte[] buffer = new Byte[nbytes];
rmd.QueryDatabaseBuffer(buffer);
File.WriteAllBytes("text.txt", buffer);

rdata.RegisterUser();
id++;
AddDatabase(id);

faceData.Dispose();
}

I check the value of numOfFaceDetected return the right number of face detected. But, when I try to get the nbytes values, it returns null. But when I check in debug mode rmd.QueryDatabaseSize(); has unique value. Any solution? thanks

This is known issue and we will fix it in the future release. Thanks for supporting RealSense SDK.

i think you can save a

i think you can save a serialized data to be *.dat file instead of saving it into txt file :D

oh, i suggest you to develop

oh, i suggest you to develop your apps in windows form. i have developed a WPF apps and i got unknown error, but when i develop it in windows form, using same algorithm, i had no error

Hi David,

I saved Face Data to a .dat file. Next time RealSense demo starts, it automatically load the .dat file. But after the same face into Camera's view, RealSense cannot recognize the face until about 1300ms later. In other words, after loaded registered face data, RealSense cannot recognize the face right now. I write the demo reference to DF_FaceTracking, RecognitionModuleData::QueryDatbaseBuffer() is used to save face data, RecognitionConfiguration::SetDatabaseBuffer() is used to load face data. Do anything else need I to do? Thank you.
