Images, associated clinical data, annotations, and diagnoses
The Cancer Imaging Archive (TCIA) is a service that de-identifies and hosts a large archive of medical images of cancer accessible for public download.
There are 20 Image Datasets for Computer Vision Training in different forms, such as video sequences, views from multiple cameras at different angles, or multi-dimensional data from a medical scanner.
Special Database 19 contains NIST’s entire corpus of training materials for handprinted documents and character recognition. It publishes Handprinted Sample Forms from 3600 writers, 810,000 character images isolated from their forms, ground truth classifications for those images, reference forms for further data collection, and software utilities for image management and handling.
