@SdeGeata
Sorry to hear that you have some issue to install OpenCV. Which Hardware do you have? On my Raspi 3+ it works fine, first run and all compiled.

Whats really important is that you extend your Swap, otherwise you will have some issues like you described.

Did you go through this documentation? https://www.pyimagesearch.com/2018/09/26/install-opencv-4-on-your-raspberry-pi/

sudo nano /etc/dphys-swapfile

# set size to absolute value, leaving empty (default) then uses computed value
#   you most likely don't want this, unless you have an special disk situation
# CONF_SWAPSIZE=100
CONF_SWAPSIZE=2048

sudo /etc/init.d/dphys-swapfile stop
sudo /etc/init.d/dphys-swapfile start

Note: Increasing swap size is a great way to burn out your Raspberry Pi microSD card. Flash-based storage have limited number of writes you can perform until the card is essentially unable to hold the 1’s and 0’s anymore. We’ll only be enabling large swap for a short period of time, so it’s not a big deal.

Software:
Here you will find a good installation guide.

Hardware:
I would suggest that you use a Raspberry Pi 3 or 4. (4 was just released, so maybe not in stock everywhere). And then you need a Display and a Mirror (2 Way Mirror / Spy Mirror). And finally build a frame where you can all put togheter.

Checkout the Forum and you will find a lot examples.

@SdeGeata
Hi,
Now it’s finally done and tested on my own Magic Mirror with the PiCamera. Let me know if you have any issues and need some help.

Module are now Final and tested on real MagicMirror

@toexelchen
Hi Carsten. You can also use my module :)

Genau 👍

@thedoorsfanatic

Die Änderung am Modul wurden akzeptiert und sind in der neuen Version drin.

Hi all

Because our “old” MMM-Facial-Recognition-OCV3 module is not working fine for me and is some days old i decided to create a new module with OpenCV 4.1 and Deep Neural Network to recognize faces. Thanks to normyx for this great module and inspiration for my own new one.

Over all it is compatible with the module from normyx, you can use it over the same classes as he used. The training of the images are a little bit different but much easier as his version (for my point of view).

To be honest the development status are still beta, i finished the module yesterday evening and tested it on my macbook and not yet on my mirror. But this tests on my local machine was successfully.

So if you want try it out and let me know what you think about and what i can extend / change or whatever.

Happy to hear your experiences with the module and how it works with your mirror.

Please read carefully the readme of the module, i hope i don’t forget something, otherwise, also please let me know and i can change it or extend it. Happy to help where i can.

If you find a bug, so let me know with a ticket on GitHub or feel free to do a Pull Request, i will check it as fast as i can.

Thanks for your Feedback.

@sdetweil oh i only read the error, my fault, sorry.

sh is a command which is runing on unix systems (such as macos, linux) do you try that on a windows machine?
