    @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?

      @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:

      [MMM-Facial-Recognition] Facerecognition started...
      [MMM-Facial-Recognition] Loading training data...
      [MMM-Facial-Recognition] ALGORITHM: LBPH

      @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).

              @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

              We're all stories in the end. Just make it a good one, eh?

                @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.

                  Well that could also be a cause. You should use the same camera for best results!
                  Why shouldn’t you be able to use a webcam with the capture script? I never used it with anything else to be honest :D

                    @paviro hmm. Just can’t get it working for some reason… will try again. It complaind about no picam. Maybe I have to change something in the script? I’ll du another try.

                      Well the capture script does not have an enforce webcam option. Try to uninstall the picam python module, it will fallback to webcam then.

                      To minimize recognition errors the MagicMirror module requires two identical recognitions to be accepted as current user. If your training data is not good enough it could happen that you are never recognized twice in two directly following images -> Always unknown user.
