MedMNIST v2 -- A large-scale lightweight benchmark for 2D and 3D biomedical image classification
This provides a lightweight, accessible benchmark for researchers and educators in biomedical image analysis, computer vision, and machine learning, but it is incremental as it builds upon the original MedMNIST.
The authors introduced MedMNIST v2, a large-scale benchmark collection of standardized biomedical images for 2D and 3D classification, comprising 708,069 2D and 10,214 3D images across 18 datasets with various scales and tasks, and benchmarked baseline methods including neural networks and AutoML tools.
We introduce MedMNIST v2, a large-scale MNIST-like dataset collection of standardized biomedical images, including 12 datasets for 2D and 6 datasets for 3D. All images are pre-processed into a small size of 28x28 (2D) or 28x28x28 (3D) with the corresponding classification labels so that no background knowledge is required for users. Covering primary data modalities in biomedical images, MedMNIST v2 is designed to perform classification on lightweight 2D and 3D images with various dataset scales (from 100 to 100,000) and diverse tasks (binary/multi-class, ordinal regression, and multi-label). The resulting dataset, consisting of 708,069 2D images and 10,214 3D images in total, could support numerous research / educational purposes in biomedical image analysis, computer vision, and machine learning. We benchmark several baseline methods on MedMNIST v2, including 2D / 3D neural networks and open-source / commercial AutoML tools. The data and code are publicly available at https://medmnist.com/.
