ICCV2017 - Predicting Human Activities Using Stochastic Grammar.

Files in the repository:

• cpp: grammar induction code. Instructions for running the code can be find here: https://github.com/SiyuanQi/madios
• matlab: scripts mainly used for skeleton processing and feature extraction.
• python: files for low-level classifiers and grammar inference.

Important notes

• The cpp folder contains code for learning grammar. For parsing/inference, most grammar related code are in python/grammarutils.py.
• If you want to use the code for future prediction, you need to modify the nltk library according to the instructions here.

If you find this code useful, please cite our work with the following bibtex:
