2.0.2 (2024-11-12)

  • Added feature to conditionally trigger face recognition to start and stop via a Magic Mirror notification. Use of this feature is optional. Use for example with MMM-Pir to turn off face recognition when monitor is off, and back on when monitor is on.
    • node_helper sends commands to the python child process via its std input upon receiving an external notfication.
    • CPU utilization of python process is substatially reduced while face recognition is paused. RPi power consumption also reduced
  • Added SIGTERM signal handling to recognition.py so python process reliably stops when Magic Mirror application is terminated
  • Improved recognition.py loop timing so the target interval specified by checkInterval is better enforced by the main loop

2.0.1 (2023-11-01)

  • After a lot of install issues. We removed pipenv again and changed the install-instructions
    • For Bookworm we added an extra install step for an virtual environment

2.0.0 (2023-10-01)

Breaking Changes

  • Following Settings have changed and are breaking changes
    • cascade - chnage default path according to the new folder structure
    • encodings - chnage default path according to the new folder structure
    • usePiCamera and source - not avialable anymore because of auto-detection with picamera2 library
    • brightness - new possible values are 0-100
    • contrast - new possible values are 0-127
    • rotateCamera - new possible values are -1 = no rotation, 0 = 90°, 1 = 180°, 2 = 270°
    • pythonPath - still works if you like to use it, but it is not necessary anmore with pipenv
    • resolution - default resolution was changed from [1280, 960] to [1920,1080]
  • Some old OS images are not supported anymore according to picamera2

Folder structure

  • Move haarcascade from tools to model
  • encodings.pickle is now by default in folder model
  • Dockerfile was removed because of new simple setup
  • Makefile was removed because of new simple setup
  • facerecognition.py was renamed to recognition.py
  • Split recognition.py functions into mulitple utils files

pipenv

  • To be sure everything is installed what is needed for this module we implemented pipenv and add all dependencies automaticly with pip and pipenv. It will be installed after npm install.

Camera support

  • We use the new picamera2 library to read the camera image. It should support all the picameras and some third party cameras.

OS support

  • Because we use the picamera2 libary, we support Raspberry Pi OS Bullseye (or later) 32bit and 64bit.

  • Picamera2 is not supported on:

    • Images based on Buster or earlier releases.
    • Raspberry Pi OS Legacy images.
    • Bullseye (or later) images where the legacy camera stack has been re-enabled.

NPM scripts

  • We have new npm scripts which helps to setup the module
    • npm run encode
    • npm run recognition
