CID — Cow Images Dataset for Regression & Classification

A curated dataset of cattle images and metadata intended for computer vision and machine learning tasks such as weight estimation (regression) and breed classification. This repository provides links to the image archives and the primary CSV metadata file used in our experiments.

Overview

Cattle livestock trading and management are growing rapidly. Accurate, automated tools for estimating weight and identifying breed from images can help producers, researchers, and agritech solutions make better decisions at scale. CID (Cow Images Dataset) was created to support research in these areas and to provide a reproducible dataset for benchmarking.

Key features:

• High-quality images of cows suitable for computer vision tasks.
• A CSV metadata file with labels and measurements for supervised learning.
• Separate archive of YouTube-sourced images for additional variability.

Quick start

1. Download and extract the image archives:

wget https://cid-21.s3.amazonaws.com/images.tar.gz
tar -xzf images.tar.gz

wget https://cid-21.s3.amazonaws.com/yt_images.tar.gz
tar -xzf yt_images.tar.gz

1. Download the metadata CSV:

wget https://cid-21.s3.amazonaws.com/dataset.csv

1. Example: preview the CSV with Python (pandas)

import pandas as pd

df = pd.read_csv("dataset.csv")
print(df.head())
print(df.info())

1. Example: load images for training (PyTorch example outline)

from torchvision import transforms
from torchvision.datasets import ImageFolder
from torch.utils.data import DataLoader

transform = transforms.Compose([
    transforms.Resize((224, 224)),
    transforms.ToTensor(),
])

dataset = ImageFolder(root="images", transform=transform)
loader = DataLoader(dataset, batch_size=32, shuffle=True)

Adjust preprocessing and model architecture to suit regression or classification tasks.
