        @bhepler Thank you for your suggestion.

        I already have this functionality. (Using my NAS´s “Synology Surveillance Station”).
        If a “motion” is detected, I get an “Alert Notification” with a Mjpeg-Stream on my Magic Mirror. Every motion is reported,
        so I get a lot of “false positive”.

        I would prefer a face detection (and I´m wondering why software like “Motion” and the “Surveillance Station” does not implement these feature.)

        Any OpenCV Gurus in the house?

          Hi,

          I have an issue with magicmirror not detecting my face. I got the training right and verified with the twst tool. The test tool recognizes me very good and quickly.

          But whan i launch MM, I just get:
          User undefined with confidence null logged in.

          I tried tweaking the threshold values, but maybe not doing it right.

          Any ideas? Pulling my hair here :-)

              Are you sure you put the training .xml file in the right place? Are you sure the training name syntax in your confis.jsg file matches the output from the train.py program you ran? those are about the only 2 things I can think of. Double check those and if you havent found the problem yet post the output from train.py and your config.js

                @nuckinfutz Im not sure, tried to put it in the root of the Facial recognition module first, but for some reason it couldnt open the file there (permissons maybe?) So I changed the path in the config.js file to the files original location, (where the training script places it).

                I will post output from train.py and my config.js when I get home.

                Thoughts of mine:
                Is it possible that the web cam captures to low resolution compared to the test script? How do one go avout changing that?

                Some permissions problem? Root vs pi user?

                If I set the confidence threshold to a much higher number, wouldn’t it eventually recognise anyone as me? (I only have one user)

                Thanks for the help!

                  Ok here is the output from train.py:

                  pi@raspberrypi:~/MagicMirror/modules/MMM-Facial-Recognition-Tools-master/facetrainer $ sudo python train.py
                  Which algorithm do you want to use?
                  [1] LBPHF (recommended)
                  [2] Fisherfaces
                  [3] Eigenfaces
                  --> 1
                  
                  Reading training images...
                  --------------------
                  Assign label 1 to Johannes
                  --------------------
                  
                  Read 13 positive images and 400 negative images.
                  
                  13 images from subject Johannes
                  --------------------
                  
                  Training model...
                  Training data saved to training.xml
                  
                  Please add or update (if you added new people not just new images) ['Johannes'] 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).

                    @paviro Do you think it can be possible to have a “CURL” call when a user log in and log out ?

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

                        @bhepler thanks! Tried that but still no luck. Started over from scratch, still undefined user. The. Lowercase was me testing if it made any difference.

                        Cound it be that the webcam captures in too low res when running MM compare to the test script? And in that case, how can I check or change that?

                        Im a noob with linux and the terminal.
