A Hugging Face dataset of pre-processed brain activity flat maps from the Natural Scenes Dataset, constrained to a visual cortex region of interest and rendered as PNG images.

Load the dataset

Load the dataset from Hugging Face Hub

python

from datasets import load_dataset

dataset = load_dataset("clane9/NSD-Flat", split="train")

Building the dataset

1. Download source data

Run `download_data.sh` to download the required source data:

—NSD stimuli images and presentation info
—COCO annotations
—NSD beta activity maps in fsaverge surface space

bash

bash download_data.sh

2. Convert the COCO annotations

Run `convert_nsd_annotations.py` to crop and reorganize the COCO annotations for NSD.

bash

python convert_nsd_annotations.py

3. Generate the dataset

Run `generate_dataset.py` to generate the huggingface dataset in Arrow format.

bash

python generate_dataset.py --img_size 256 --workers 8
