A pytorch-version implementation codes of paper: "BSN++: Complementary Boundary Regressor with Scale-Balanced Relation Modeling for Temporal Action Proposal Generation", which is accepted in AAAI 2021.

[Arxiv Preprint]

These code is implemented in Pytorch 1.5.1 + Python3 .

The author rescaled the feature length of all videos to same length 100, and he provided the rescaled feature at BaiduCloud [Code:efy8].

All configurations of BSN++ are saved in opts.py, where you can modify training and model parameter.

1. To train the BSN++:

python main.py --mode train

2. To get the inference proposal of the validation videos and evaluate the proposals with recall and AUC:

python main.py --mode inference

Of course, you can complete all the process above in one line:

sh bsnpp.sh

This implementation largely borrows from BMN by JJBOY.
