Facial Recognition - customize your mirror for every user!

benkej

Hi guys,

I have the same problem, tried with picam and normal webcam too.
Capture working, train working, facerecognition_tester working, MMM-Facial-Recognition doesn’t work.

Anyone sitting in front of the mirror, I get the message in terminal “User undefined with confidence null logged in”

@YourhighnessLeender Webcam is fine. If it worked in training it will work in the module.

@nuckinfutz that is whats so strange. It does work in training but not in the module. Did a new install of the module and new training.xml but no luck. Very very wierd.

Maybe I should buy a picam and try with that.

@benkej question: did you change any of the capture settings in config.js? Like threshold etc? I was thinking of trying a different algorithm, did you try that?

benkej

@YourhighnessLeender only for trial but I changed everything back to the default. I’m using raspberry pi 3 model b, here is part of my config:

{
    module: 'MMM-Facial-Recognition',
    config: {
        // 1=LBPH | 2=Fisher | 3=Eigen
        recognitionAlgorithm: 1,
        // Threshold for the confidence of a recognized face before it's considered a
        // positive match.  Confidence values below this threshold will be considered
        // a positive match because the lower the confidence value, or distance, the
        // more confident the algorithm is that the face was correctly detected.
        lbphThreshold: 50,
        fisherThreshold: 250,
        eigenThreshold: 3000,
        // force the use of a usb webcam on raspberry pi (on other platforms this is always true automatically)
        useUSBCam: true,
        // Path to your training xml
        trainingFile: 'modules/MMM-Facial-Recognition/training.xml',
        // recognition intervall in seconds (smaller number = faster but CPU intens!)
        interval: 3,
        // Logout delay after last recognition so that a user does not get instantly logged out if he turns away from the mirror for a few seconds
        logoutDelay: 15,
        // Array with usernames (copy and paste from training script)
        users: ["Jani"],
        //Module set used for strangers and if no user is detected
        defaultClass: "default",
        //Set of modules which should be shown for every user
        everyoneClass: "everyone"
    }
}

and part of console log:

@YourhighnessLeender and the output of train.py:

Which algorithm do you want to use?
[1] LBPHF (recommended)
[2] Fisherfaces
[3] Eigenfaces
--> 1

Reading training images...
--------------------
Assign label 1 to Jani
--------------------

Read 3 positive images and 400 negative images.

3 images from subject Jani
--------------------

Training model...
Training data saved to training.xml

Please add or update (if you added new people not just new images) ['Jani'] inside config.js (mirror module) or config.py (model tester). You can change the names to whatever you want, just keep the same order and you'll be fine.
Please add 1 as your choosen algorithm inside config.js (mirror module) or config.py (model tester).

@benkej same as me, but no luck :-(

benkej

@YourhighnessLeender unfortunately yes :angry:
I try to reinstall the whole system

YourhighnessLeender

@benkej oke, please update on your progress. Good luck. Im very close to giving up.

@PointPubMedia Well sure but you could also write your own module listening for the notifications from my module :)

@bhepler said in Facial Recognition - customize your mirror for every user!:

@YourhighnessLeender Check your capitalization. Your training script output was ‘Johannes’ and your config.js has ‘johannes’.

This does not make any difference :)

You should definitely use more than 3 pictures! I use around 200 :D

YourhighnessLeender

@paviro 200 pictures - aha! Maybe my 13 isnt enough. I can’t use the capture script since i’m on webcam so I took em with my phone and transferred them to the pi. I’ll add more and cross my fingers.
