A weird problem of the Compare function in Face Recognition

I have performed an experiment on face recognition: using static images to aquire face models and serialize them in a file, during recognition, I compare the current model extracted from one image to compare with the deserialized models array, and their will be a scores array returned, the problem is, when I add or remove some image to the repository, the scores will be different for each image, namely, there's inconsistency even bewteen two same image's scores with the same target image.

Face detector and confidence value

Hi,

I'm trying to measure the performance of the face detector (ROC curve) but I notice that the confidence field of the PXCFaceAnalysis::Detection::Data structure is not very informative: it's always set between 0.93 and 0.99. Has anyone noticed this behavior? I used the Pointing'04 dataset (various head poses) to do the test (with SDK version 7383).

Thanks,

Marc

how to use the function of attribute_detection

According to Intel to provide for the Unity of facial analysis interface function, only the several functionssuch as:QueryFaceLandmarkData、QueryFaceLandmarkData[]、QueryFaceLandmarkPose、QueryFaceLocationData 、QueryID.

now I have question,which function I can use to show the Facial expressions? If this some function can not do it?
how can i do next!

What I mean is the accessory image display function

Raising gesture recognition resolution

Hi,

Although help mentions that "SDK gesture recognition module takes RGB, depth, or IR streams as input", it seems to me that it really takes into account just depth stream with low 320x240 resolution.

We've tried:

    EnableGesture();
    EnableImage(PXCImage::COLOR_FORMAT_RGB24,1280,720);
    
But it seems this has only to do with rendering recognized gestures in camera window, not with gesture recognition itself.

Is 320x240 the best possible resolution for gesture recognition? Does it use depth sensor only?

Many thanks,
Ivan
