CVPR 2020 - Detecting Attended Visual Targets in Video

Overview

This repo provides PyTorch implementation of our paper: 'Detecting Attended Visual Targets in Video' [paper]

We present a state-of-the-art method for predicting attention targets from third-person point of view. The model takes head bounding box of a person of interest, and outputs an attention heatmap of that person.

We release our new dataset, training/evaluation code, a demo code, and pre-trained models for the two main experiments reported in our paper. Pleaser refer to the paper for details.

Getting Started

The code has been verified on Python 3.5 and PyTorch 0.4. We provide a conda environment.yml file which you can use to re-create the environment we used. Instructions on how to create an environment from an environment.yml file can be found here.

Download our model weights using:

sh download_models.sh

Quick Demo

You can try out our demo using the sample data included in this repo by running:

python demo.py

Experiment on the GazeFollow dataset

Dataset

We use the extended GazeFollow annotation prepared by Chong et al. ECCV 2018, which makes an additional annotation to the original GazeFollow dataset regarding whether gaze targets are within or outside the frame. You can download the extended dataset from here (image and label) or here (label only).

Please adjust the dataset path accordingly in config.py.

Evaluation

Run:

python eval_on_gazefollow.py

to get the model's performance on the GazeFollow test set.

Training

Run:

python train_on_gazefollow.py

to train the model. You can expect to see similar learning curves to ours.

Experiment on the VideoAttentionTarget dataset

Dataset

We created a new dataset, VideoAttentionTarget, with fully annotated attention targets in video for this experiment. Dataset details can be found in our paper. Download the VideoAttentionTarget dataset from here.

Please adjust the dataset path accordingly in config.py.

Evaluation

Run:

python eval_on_videoatttarget.py

to get the model's performance on the VideoAttentionTarget test set.

Training

Run:

python train_on_videoatttarget.py

to do the temporal training.
