TempSAL - Uncovering Temporal Information for Deep Saliency Prediction - CVPR 2023

An example of how human attention evolves over time. Top row: Temporal (shown in orange) and image (shown in pink) saliency ground truth from the SALICON dataset. Bottom row: Our temporal and image saliency predictions. Each temporal saliency map $\mathcal{T}_i$, $i \in {1,\ldots,5}$ represents one second of observation time. Note that in $\mathcal{T}_1$, the chef is salient, while in $\mathcal{T}_2$ and $\mathcal{T}_3$, the food on the barbecue becomes the most salient region in this scene. We can predict the temporal saliency maps for each interval separately, or combine them to create a single, refined image saliency map for the entire observation period.

Installing required packages

Install the packages with pip using the following command under src/ folder.

pip install -r requirements.txt

Inference

Download the model checkpoint from: https://drive.google.com/drive/folders/1W92oXYra_OPYkR1W56D80iDexWIR7f7Z?usp=sharing

Follow the instructions on inference.ipynb. This notebook provides predictions on temporal and image saliency together.

Data

Download temporal saliency ground-truth saliency maps and fixations produced from the SALICON dataset : https://drive.google.com/drive/folders/1afangzz2JFxRfRkQ-shjnhp8OyJCXL3G?usp=drive_link

Alternatively, you can use generate_volumes.py to produce temporal saliency slices in desired intervals&numbers.

Temporal saliency only
