Data Instances

Species Classification (FV-419): classification_<split>.csv
- Approximately 48K images of 419 species for species classification tasks.
- There are about 35K training, 7.6K test, and 5K validation images.
Trait Identification (FV-682): identification_<split>.csv
- Approximately 53K images of 682 species for trait identification based on species-level trait labels (i.e., presence/absence of traits based on trait labels for the species from information provided by Phenoscape and FishBase).
- About 38K training, 8K test_insp (species in training set), 1.9K test_lvsp (species not in training), and 5.2K validation images.
- Train, test, and validation splits are generated based on traits, so there are 628 species in train, 450 species in test_insp, 51 species in test_lvsp, and 451 in the validation set (3 species only in val).
Trait Segmentation (FV-1200): segmentation_<split>.csv
- Pixel-level annotations of 9 different traits for 2,427 fish images.
- About 1.7k training, 600 test and 120 validation images for the segmentation task
- These are also used as manually annotated test set for Trait Identification.
All Segmentation Data: segmentation_data.csv
- Essentially a collation of the trait segmentation splits
- Used for evaluating trait identification on the entire FV-1200
Image Information
- Type: JPG
- Size (x pixels by y pixels): Variable
- Background (color or none): Uniform (White)

Data Fields

CSV Columns are as follows:

filename: Unique filename for our processed images.
source_filename: Filename of the source image. Non-unique, since one source filename can result in multiple crops in our processed dataset.
original_format: Original format, all jpg/jpeg.
arkid: ARKID from FishAIR for the original images. Non-unique, since one source file can result in multiple crops in our processed dataset.
family: Taxonomic family

barbel: Presence/absence of the barbel trait. NA for the classification (FV-419) dataset, since it is only used for identification. 1 indicates presence and 0 indicates absence. This is used for trait identification.
multiple_dorsal_fin: Presence/absence of the dorsal fin trait. NA for the classification (FV-419) dataset, since it is only used for identification. 1 indicates presence, 0 indicates absence and -1 indicates unknown. This is used for trait identification.

Data Splits

For each task (or subset), the split is indicated by the CSV name (e.g., classification_<split>.csv). More information is provided in Data Instances, above.

Example Code to Use the Segmentation Dataset

We provide an example code to use the FV-1200 segmentation dataset for convenience of users. Please install pillow, numpy, pandas and matplotlib before trying the code:

from PIL import Image
import os 
import numpy as np
import pandas as pd
import matplotlib.pyplot as plt
import json

# Set the the fish_vista_repo_dir to the path of your cloned fish-vista HF repository. This code assumes you are running from within the fish-vista directory
fish_vista_repo_dir = '.'

# segmentation_masks/images contains the annotated segmentation maps for the traits. 
# If image filename is <image_filename>.jpg, the corresponding annotation is contained in segmentation_masks/images/<image_filename>.png 
seg_mask_path = os.path.join(fish_vista_repo_dir, 'segmentation_masks/images')

# seg_id_trait_map.json maps the annotation id to the corresponding trait name.
# For example, pixels annotated with 1 correspond to the trait: 'Head'
id_trait_map_file = os.path.join(fish_vista_repo_dir, 'segmentation_masks/seg_id_trait_map.json')
with open(id_trait_map_file, 'r') as f:
    id_trait_map = json.load(f)

# Read a segmentation csv file
train_path = os.path.join(fish_vista_repo_dir, 'segmentation_train.csv')
train_df = pd.read_csv(train_path)

# Get image and segmentation mask of image at index 'idx'
idx = 0
img_filename = train_df.iloc[idx].filename
img_mask_filename = os.path.splitext(img_filename)[0]+'.png'
# Load and view the mask 
img_mask = Image.open(os.path.join(seg_mask_path, img_mask_filename))
plt.imshow(img_mask)

# List the traits that are present in this image
img_mask_arr = np.asarray(img_mask)
print([id_trait_map[str(trait_id)] for trait_id in np.unique(img_mask_arr)])

Dataset Details

Dataset Description

The Fish-Visual Trait Analysis (Fish-Vista) dataset is a large, annotated collection of 60K fish images spanning 1900 different species; it supports several challenging and biologically relevant tasks including species classification, trait identification, and trait segmentation. These images have been curated through a sophisticated data processing pipeline applied to a cumulative set of images obtained from various museum collections. Fish-Vista provides fine-grained labels of various visual traits present in each image. It also offers pixel-level annotations of 9 different traits for 2427 fish images, facilitating additional trait segmentation and localization tasks.

The Fish Vista dataset consists of museum fish images from Great Lakes Invasives Network (GLIN), iDigBio, and Morphbank databases. We acquired these images, along with associated metadata including the scientific species names, the taxonomical family the species belong to, and licensing information, from the Fish-AIR repository.

Dataset Creation

Curation Rationale

Fishes are integral to both ecological systems and economic sectors, and studying fish traits is crucial for understanding biodiversity patterns and macro-evolution trends. Currently available fish datasets tend to focus on species classification. They lack finer-grained labels for traits. When segmentation annotations are available in existing datasets, they tend to be for the entire specimen, allowing for segmenation of background, but not trait segmentation. The ultimate goal of Fish-Vista is to provide a clean, carefully curated, high-resolution dataset that can serve as a foundation for accelerating biological discoveries using advances in AI.

Source Data

Images and taxonomic labels were aggregated by Fish-AIR from

Phenoscape and FishBase were used to provide the information on traits at the species level.

Open Tree Taxonomy was used to standardize the species names provided by Fish-AIR.

Data Collection and Processing


Figure 4. An overview of the data processing and filtering pipeline used to obtain Fish-Vista.

We carefully curated a set of 60K images sourced from various museum collections through Fish-AIR, including Great Lakes Invasives Network (GLIN), iDigBio, and Morphbank. Our pipeline incorporates rigorous stages such as duplicate removal, metadata-driven filtering, cropping, background removal using the Segment Anything Model (SAM), and a final manual filtering phase. Fish-Vista supports several biologically meaningful tasks such as species classification, trait identification, and trait segmentation.

Annotations

Annotation process

Phenoscape and FishBase were used to provide the information on species-level traits (the species-trait matrix).

Open Tree Taxonomy was used to standardize the species names provided by Fish-AIR.

Image-level trait segmentations were manually annotated as described below.

The annotation process for the segmentation subset was led by Wasila Dahdul. She provided guidance and oversight to a team of three people from NEON, who used CVAT to label nine external traits in the images. These traits correspond to the following terms for anatomical structures in the UBERON anatomy ontology:

Eye, UBERON_0000019
Head, UBERON_0000033
Barbel, UBERON_2000622
Dorsal fin, UBERON_0003097
Adipose fin, UBERON_2000251
Pectoral fin, UBERON_0000151
Pelvic fin, UBERON_0000152
Anal fin, UBERON_4000163
Caudal fin, UBERON_4000164

Personal and Sensitive Information

None

Considerations for Using the Data

Discussion of Biases and Other Known Limitations

This dataset is imbalanced and long tailed
It inherits biases inherent to museum images
Train sets may contain noisy images (in very small numbers)

Recommendations

Licensing Information

The source images in our dataset come with various licenses, mostly within the Creative Commons family. We provide license and citation information, including the source institution for each image, in our metadata CSV files available in the HuggingFace repository. Additionally, we attribute each image to the original FishAIR URL from which it was downloaded.

A small subset of our images (approximately 1k) from IDigBio are licensed under CC-BY-ND, which prohibits us from distributing processed versions of these images. Therefore, we do not publish these 1,000 images in the repository. Instead, we provide the URLs for downloading the original images and a processing script that can be applied to obtain the processed versions we use.

Our dataset is licensed under CC-BY-NC 4.0. However, individual images within our dataset may have different licenses, which are specified in our CSV files.
