Facial Recognition - customize your mirror for every user!

j.e.f.f

@paviro I’ve switched to using the Pi cam for facial recognition, and my confidence numbers have improved significantly, but it still takes a good 5 seconds of standing absolutely still looking right at the camera to get it to work. I’ve trained the model with about 40 images of myself standing at various distances from the camera, sometimes looking right at it, other times staring blankly ahead (as if I were looking in the mirror).

Is 5 seconds the best I can hope for, or does it work faster for others? I have the frequency configured to interval : 1 although I don’t see much difference between 1 and 2 (or anything smaller than 1).

hello,
After a few months of sleep, I wake up my mirror
i’ve just update the raspberry and the MagicMirror to the last version
also this module (facial recognition) to see if it works better
but when i try to make the training.xml with train.py, i’ve this error :

Reading training images...

Assign label 1 to Gael

anyone could help me ?
Thanks

@lepetitnicolas Just saw this but here is the fix

cd home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools
sudo pip install future --upgrade

This may not be an appropriate place but is there a good resource / tutorial for setting up / configuring the modules for the mirror? I’m specifically interested in facial recognition and the calendars - so far I only have the basic mirror installed.

@nuckinfutz
thanks, i do what you saw but i have the same error…

I can’t seem to get the module to work properly. I made pictures and generated a training.xml file. When I test said file it does identify me.

However, I can’t find a user array in the training file to add to the config.xml. When I add the only user present it still doesn’t work

xchribiza

I have managed to make this module to work finally…BUT …
I have one user (since I have just set it up) and it recognises me well etc…but it recognises other people as ME ???
Why ??
Is there something to be done ?

Anyone able to help me out with this? :)

Hello everyone

the class ‘everyone’, which should activate a module for every person, dont work for me. the clock-module for example stay inactive, no matter wich person is detected. The config looks like this:

{
module: “clock”,
position: “top_left”,
classes: “everyone”
},

Work this class for anyboby?

@reaper81 I think you also need to include the class default as the facial recognition app spends most of its time logged out.

reaper81

@j.e.f.f

the default-class works fine but i whould like to show modules only if a person is in the room. thats why the class “everyone” exist. Do you use it? does it work?

j.e.f.f

@reaper81 yeah in that case it should work for what you’re trying to do. If it isn’t then I don’t know why.

You could also try using a motion sensor to turn the screen on and off. Essentially when someone walks up to the screen it shows modules, and after a specified time out of no motion sensed, if turns itself back off.

reaper81

So i repeat my question: does anybody use the “everyone”-class and it work?

I am struggling to get modules using a name class to work. Still waiting for an answer as well

Hey guys. I’m having difficulty using my webcam with the capture.py script. I’m able to use fswebcame and motion to capture video but I keep getting errors running the script. I’m using a the playstion eye as a webcam. Any ideas?

Hi there, maybe someone is able to help me out.
I am trying to run capture.py but getting this Error

I am also facing the same issue. Any effort to resolve it will be appreciated.

Are you using OpenCV 3.3? Then i might can help you.

Got another problem. My picam is not able to open. I am using opencv 3.3.

Remember to set the name list environment variable FACE_USERS
Using default FACE_ALGORITM: 1
Traceback (most recent call last):
File "facerecognition.py", line 30, in 
camera = config.get_camera(preview)
File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/config.py", line 101, in get_camera
return webcam.OpenCVCapture(device_id=0)
File "/home/pi/MagicMirror/modules/MMM-Facial-Recognition-Tools/lib/webcam.py", line 29, in __init__
self._camera.open()
TypeError: Required argument 'device' (pos 1) not found

any suggestions?
