MMM-Face-Reco-DNN - All new Face Recognition

Is it working fine??

Depends on how you define working fine…The face recognition is working quite good, setting it up is easy with the advice you get in this thread. For me it’s just the “slow” reaction to activate the display which is an issue. But I’m optimistic that there is a way to solve it and I have a special environment with a display which hasn’t CEC control.

@ChrizZz
Yes i know this issue. i’m currently working on a bugfix. will tell you if i’m done.

I am turning on the monitor using a PIR sensor and it is instant. Keep in mind that it also depends on your monitor, some are slower to respond - this is my second monitor, the first one was very slow to respond to any HDMI related commands.

I have a new strange error and I think it’s just if I restart mm with “pm2 restart mm”. If I reboot my pi, everything is fine.

I get this too, when my PI can’t connect to the camera. I know that, because if i use
Raspistill -o s.jpg
I will get an error there too. A reboot seems to fix it though. I don’t know what makes it happen, but i suspect the cable.

sdetweil

@Blauenfeldt the python code returns an error, but the module does not expect it, and fails.

rjlinden

Will this work if the camera is rotated? If not, can you tell me where I need to change the code?

Hi,

when im trying to install the face_recogtnition I’m getting this error code:

Does anybody know how to fix this/what is causing this?
Sorry if it’s obvious, im a super noob with this kind of stuff

Cheers

Try this :

pip --no-cache-dir install face_recognition
-python setup.py install

What is the best camera for this module ?
Pi NoIR Camera V2

Or

Camera Module V2

https://www.raspberrypi.org/products/camera-module-v2/

Thanks for advance :)

@gaudouy
Thank you, seems like that worked.

But now I am getting following error when I’m trying to run “encode.py”

Python 3.7.3 (/usr/bin/python3)
>>> %Run encode.py
Traceback (most recent call last):
  File "/home/pi/MagicMirror/modules/MMM-Face-Reco-DNN/tools/encode.py", line 5, in <module>
    from imutils import paths
ModuleNotFoundError: No module named 'imutils'
>>>

But when I’m installing “imutils” using “pip install imutils” I am getting no error, but following message:

Looking in indexes: https://pypi.org/simple, https://www.piwheels.org/simple
Requirement already satisfied: imutils in ./.local/lib/python2.7/site-packages (0.5.3)

Any Idea how to fix that?

And to your best camera question for this module, I’m using the PiCamera Module v.2, but I can’t tell you how good its working, since the Face-Reco is not working yet…

@nischi
First off, I love your module. Well done. Its lots of fun.

Question - How can I display the frame/view of the camera on the magic mirror?
I would like to see what the camera sees on the screen in Magic Mirror. So I can see the display and the little green boxes with the names of the faces it recognises. Do you know what I would need to do to display the camera frame with the facial recognition code running the scans/outputs on screen?

ghiesseldorf

@nischi If a user who isn’t known by Face-Reco-DNN moves in front of the camera, is a notification message generated and picked up by MMM-MotionControl? It doesn’t look like the “default” and/or “everyone” classes toggles the screen to un-blank. I was expecting that ANY motion (changes in the capture frames from the camera) would un-blank, but I’m not seeing this behavior. No log-in message gets written to the log.

Alphons

@boppersnr i also want to know.

This feature is not implemented, sorry. Maybe create a ticket in github?

Mattheww

@nischi In my case classes doesn’t work. I was testing this at a bunch of different modules and always was the same resault, nothing change if classes was defined or not. The face recognition is working I tested it with python. But in modules MMM-Face-Reno-DNN I can’t run classes. Whats more I need to run or where I need to look for a trouble and what can I do to solve it.

Aquamannno

@nischi when I bring this up only a black screen appears with me listing my name but what about the rest of the modules in the magic mirror could be nice with a photo of the recognized precision I find only this (jimbydude / MMM-Face-Multi -User-Recognition-SMAI)
is picked up by magic mirror without error and stops you who are so incredibly good please come up with a variant with photo and welcome greetings.looking forward to the changes. and on whore 1000 thanks.
