Smart media tagging for Nextcloud

This app goes through your media collection and adds fitting tags, automatically categorizing your photos and music.

• 📷 👪 Recognizes faces and groups photos by face
• 📷 🏔 Recognizes animals, landscapes, food, vehicles, buildings and other objects
• 📷 🗼 Recognizes landmarks and monuments
• 👂 🎵 Recognizes music genres
• ⚡ Tagging works via Nextcloud's Collaborative Tags, allowing access by any of your apps
  • 👂 listen to your tagged music with the audioplayer app
  • 📷 view your tagged photos with the photos app

This app does not send any sensitive data to cloud providers or similar services. All image processing is done on your nextcloud machine, using Tensorflow.js running in Node.js, which comes bundled with this app.

This is the list of recognized things and which categories they are currently mapped to. I'm happy to accept pull requests for this file to fine tune predictions.

Recognize uses

• a pre-trained EfficientNet v2 model for ImageNet object detection.
• a pre-trained model trained on the Landmarks v1 dataset for landmark recognition.
• face-api.js to extract and compare face features.
• a Musicnn neural network architecture to classify audio files into music genres. Also see the original musicnn repository.
• a pre-trained MoViNet model for video classification

• php 7.4 and above
• App "collaborative tags" enabled
• For native speed:
  • Processor: x86 64-bit (with support for AVX instructions)
  • System with glibc (usually the norm on Linux; Alpine linux and FreeBSD are not such systems)
• For sub-native speed (using JavaScript mode)
  • Processor: x86 64-bit, arm64, armv7l (no AVX needed)
  • System with glibc or musl (incl. Alpine linux)
• ~4GB of free RAM (if you're cutting it close, make sure you have some swap available)

Go to "Apps" in your nextcloud, search for "recognize" and click install.
