A collection of 10 pre-processed medical open datasets. MedMNIST is standardized to perform classification tasks on lightweight 28x28 images, which requires no background knowledge. Source: MedMNIST Classification Decathlon: A Lightweight AutoML Benchmark for Medical Image Analysis

MedMNIST v2 is a large-scale MNIST-like collection of standardized biomedical images, including 12 datasets for 2D and 6 datasets for 3D. All images are pre-processed into 28 x 28 (2D) or 28 x 28 x 28 (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 data 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.

MedMNIST-C is an open-source data set collection comprising algorithmically generated corruptions applied to the test sets of the MedMNIST collection following the concept of ImageNet-C. To maintain the integrity of the medical data, we have excluded any weather-dependent corruptions (“Snow”, “Frost”, “Fog”). Hence, each data set in the MedMNIST-C collection comprises 16 different corruptions (12 test corruptions and 4 validation corruptions) spanning 5 severity levels. For further information on the corruptions visit the original GitHub repository of ImageNet-C.
