Facial Recognition - customize your mirror for every user!

Hello!
I have an problem wirth the Facial Regonition Module. I have tried it with the PiCam and an normal webcam. It worked not really good with die webcam and after i’ve tried it with die PiCam it doesn’t work any more. I’ve updatet the config.js.
This is the npm output:
config.js:
On the mirror nothing is shown. { 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-Tools/training.xml', // recognition intervall in seconds (smaller number = faster but CPU intens!) interval: 1, // 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: ['Jenny'], //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", // Boolean to toggle welcomeMessage welcomeMessage: true }Any suggestions?

@mc_landin I’m at this stage as well! for some reason the classes dont change whats displayed when a new face is seen. So in this example the “default” is seen all the time and then when a generic face is seen then the “everyone” class isnt shown. Has anyone got this working?
{ module: "updatenotification", position: "top_bar", classes: 'default' }, { module: "clock", position: "top_left", classes: 'everyone' }, { module: 'MMM-Facial-Recognition', config: { recognitionAlgorithm: 1, // 1=LBPH | 2=Fisher | 3=Eigen // Threshold for the confidence of a recognized face before it's considered a // positive match.

Hi All, I have found out that if you want to use your USB webcam for training you can update the file https://github.com/paviro/MMM-Facial-Recognition-Tools/blob/master/lib/config.py in the appropriate directory with the following. for some reason it doesnt seem to want to fall over to the webcam so I just commented out the pi web cam and added the usb one.
def get_camera(preview=True): try: # from . import picam # capture = picam.OpenCVCapture(preview) # capture.start() # return capture from . import webcam return webcam.OpenCVCapture(device_id=0) capture.start() return capture except Exception: from . import webcam return webcam.OpenCVCapture(device_id=0) -
OK after lots and lots of trial and error I hope this helps people… these are the settings and results I had and as far as I can tell the everyone setting doesnt do what I would expect…
I don’t hink you have a way of identifying a stranger and do something specific for them?
defaultClass: "default", //Module set used for strangers and if no user is detectedIt looks like when everyone is specified on its own then the logic doesnt seem to work. See classes: “everyone” below…
users: ['martin'], // Array with usernames (copy and paste from training script) defaultClass: "default", //Module set used for strangers and if no user is detected everyoneClass: "everyone", //Set of modules which should be shown for every user welcomeMessage: false // Boolean to toggle welcomeMessage } }, { module: "clock", position: "top_left", classes: "default" // displays with no face detection (OK) - not displayed when martin detected (OK) - displayed with no specific user detected (OK?) }, { module: "clock", position: "top_right", classes: "default everyone" // displays with no face detection (OK) - displayed with no specific user and martin (OK) }, { module: "clock", position: "bottom_right", classes: "default martin" // displays with no face detection (OK) - displayed with no specific user and martin (OK) }, { module: "clock", position: "bottom_left", classes: "everyone" // never displays (??? I would expect this to display when Martin is detected - or any other user) }, { module: "compliments", position: "lower_third", classes: "martin" // only displayed when martin detected (OK) }, -
Hi,
I use your Facial Recognition modul. I have create some user and everything work fine.
But now I install MMM-Motion-Detection modul. I works fine, too. But if I use this modul your modul didn´t work. When I cut off the MMM-Motion-Detection module from config.js and start again your modul will work fine again.
Can someone help me?

Sorry for spaming,
but I tried to refresh everything. So I installed the Rasbian new, the Magic Mirror, the Facial Recognition and the Tools. It worked… ONCE. After rebooting the system I have the same error as bevor:
It load training data and select the PiCam and then it doesn’t go on. No error-message.
Any idea which component was active when I reinstalled everything and isn’t active after rebooting?
The camera is enabled. -
I have the same issue. Training went fine. I got everything working but then after a reboot it seems to load the module but then nothing. It doesn’t seem to want to do anything. No errors just no facial recognition.

So I figured out my own problem. Seems like it doesn’t like it when I changed the language file. Restored the old one and everything works as it should. Also, I find raising the threshold to 250 for the LBPH Algorithm helps a lot to get more accurate results. The confidence seems to hover around 49-52 for me but I couldn’t get any results with 50, constantly thought I was “stranger”. Thanks for all the hard work on this module. It’s really fun to play with!
