A PyTorch port of DeepMind's I3D (Inflated 3D ConvNet) models pretrained on the Kinetics dataset for video action recognition. It includes code for fine-tuning on Charades and extracting per-segment video features as numpy arrays.
Use cases
- recognize human actions in videos
- extract I3D features from video clips
- fine-tune a video action recognition model on my own dataset
- convert DeepMind Kinetics I3D weights to PyTorch
- classify video segments on Charades
- get per-segment embeddings for video understanding tasks
When to choose
- you need a classic pretrained video action recognition backbone in PyTorch
- you want to extract I3D features for downstream models
- you are reproducing the Quo Vadis action recognition paper or Charades challenge results
When to avoid
- you need support for recent PyTorch versions (code targets PyTorch 0.3)
- you want state-of-the-art video models rather than a 2017-era architecture
- you need maintained software with active bug fixes
