Overview

Syntax-Aware Action Targeting for Video Captioning

Code for SAAT from "Syntax-Aware Action Targeting for Video Captioning" (Accepted to CVPR 2020). The implementation is based on "Consensus-based Sequence Training for Video Captioning".

Dependencies

(Check out the coco-caption and cider projects into your working directory)

Data

Data can be downloaded here (1.6GB). This folder contains:

  • input/msrvtt: annotatated captions (note that val_videodatainfo.json is a symbolic link to train_videodatainfo.json)
  • output/feature: extracted features of IRv2, C3D and Category embeddings
  • output/metadata: preprocessed annotations
  • output/model_svo/xe: model file and generated captions on test videos, the reported result can be reproduced by the model provided in this folder (CIDEr 49.1 for XE training)

Test

make -f SpecifiedMakefile test [options]

Please refer to the Makefile (and opts_svo.py file) for the set of available train/test options. For example, to reproduce the reported result

make -f Makefile_msrvtt_svo test GID=0 EXP_NAME=xe FEATS="irv2 c3d category" BFEATS="roi_feat roi_box" USE_RL=0 CST=0 USE_MIXER=0 SCB_CAPTIONS=0 LOGLEVEL=DEBUG LAMBDA=20

Train

To train the model using XE loss

make -f Makefile_msrvtt_svo train GID=0 EXP_NAME=xe FEATS="irv2 c3d category" BFEATS="roi_feat roi_box" USE_RL=0 CST=0 USE_MIXER=0 SCB_CAPTIONS=0 LOGLEVEL=DEBUG MAX_EPOCH=100 LAMBDA=20

If you want to change the input features, modify the FEATS variable in above commands.
