[ICCV 2021] Relaxed Transformer Decoders for Direct Action Proposal Generation

Overview

RTD-Net (ICCV 2021)

This repo holds the codes of paper: "Relaxed Transformer Decoders for Direct Action Proposal Generation", accepted in ICCV 2021.

News

[2021.8.17] We release codes, checkpoint and features on THUMOS14.

RTD-Net Overview

Overview

This paper presents a simple and end-to-end learnable framework (RTD-Net) for direct action proposal generation, by re-purposing a Transformer-alike architecture. Thanks to the parallel decoding of multiple proposals with explicit context modeling, our RTD-Net outperforms the previous state-of-the-art methods in temporal action proposal generation task on THUMOS14 and also yields a superior performance for action detection on this dataset. In addition, free of NMS post-processing, our detection pipeline is more efficient than previous methods.

Dependencies

Data Preparation

To reproduce the results in THUMOS14 without further changes:

  1. Download the data from GoogleDrive.

  2. Place I3D_features and TEM_scores into the folder data.
