Seatizen Atlas Image Dataset

Dataset Card

Dataset Name: Seatizen Atlas Image Dataset
Task: Multi-label image classification
Domain: Marine Biodiversity
License: cc0-1.0
Size: 14,492 annotated images

Description

The Seatizen Atlas Image Dataset is a large-scale collection of annotated underwater images designed for training and evaluating artificial intelligence models in marine biodiversity research. It is specifically tailored for multi-label image classification tasks.

This dataset was curated by selecting only classes with more than 200 annotations to facilitate the training of computer vision models. For more information about the Seatizen Atlas Dataset, please refer to the Data paper and the Zenodo repository.

Acquisition Details

Underwater data acquisition was carried out using instrumented marine platforms. These platforms can be divided into two groups: citizen platforms and scientific platforms.

Citizen platforms paddleboards, kitesurfs, snorkeling masks equipped with cameras. Images were collected by the "Seatizen" team to promote citizen science involvement in marine research.
Scientific platforms Autonomous Surface Vehicles (ASV) equipped with a camera.

Dataset Structure

The Seatizen Atlas Image Dataset is organized as follows:

Train split: 8716 images
Validation split: 2886 images
Test split: 2890 images
