CardioMark Review Subset

This repository contains an anonymized review subset of the CardioMark benchmark introduced for automated vertebral heart score (VHS) estimation in canine thoracic radiographs.

The subset is provided to support reproducibility and data-quality inspection during peer review.

Dataset Overview

CardioMark is a large-scale benchmark for evaluating the complete VHS measurement pipeline, including:

• —cardiac landmark localization
• —geometric VHS estimation
• —threshold-based diagnosis
• —boundary sensitivity analysis
• —subgroup reliability evaluation

The complete benchmark contains:

• —21,465 lateral thoracic radiographs
• —12,385 dogs
• —144 breeds
• —six cardiac keypoint annotations per image
• —continuous VHS measurements

This repository contains a representative evaluation subset sampled from the benchmark.

Contents

The review subset includes:

• —anonymized radiographs
• —corresponding .mat landmark annotations
• —train/validation/test split structure
• —evaluation-ready file organization
