Facial Recognition - customize your mirror for every user!

[j.e.f.f]

Also one more thought: I’m thinking of turning the camera 90 degrees so that it takes a vertical image – better chance of capturing faces of people of different heights that – thinking myself as a tall adult vs my kids, 9 and 6 years old. I’m thinking a 2:3 image (or 9:16 in the case of an HD cam) would really work well here to turn a wide FoV to a “tall” FoV – perfect for people standing right in front of the mirror… If I just turn the camera 90 degrees, and use it to train and capture in that orientation, will the facial recognition algorithms work as-is (i.e.: Can they recognize a face turned sideways) or would the module need to be changed to rotate the capture first before feeding into the algorithm?

I have read all posts in this thread. Is there realy no answer why the facerecognation in the testtool is so much better than in the MM-Module?

@paviro I had a hard time getting this to play nicely with modules that show and hide themselves. I created a pull-request that addresses this:

https://github.com/paviro/MMM-Facial-Recognition/pull/48

Basically I added a lockString config option to each show and hide command, and when combined with another module that also uses a lockString the particular module is only visible when both have removed their respective lock strings.

See here for details about visibility locking:

cheers!

hello everyone,

@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
Assign label 2 to lepetitnicolas
--------------------

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

[EdChamberlain]

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.

[lepetitnicolas]

@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 ?

[mc_landin]

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?

[j.e.f.f]

@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?

[mc_landin]

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?
