ANTsRNet

A collection of deep learning architectures and applications ported to the R language and tools for basic medical image processing. Based on keras and tensorflow with cross-compatibility with our python analog ANTsPyNet.

• A large collection of common deep learning architectures for medical imaging that can be initialized
• Various pre-trained deep learning models to perform key medical imaging tasks
• Utility functions to improve training and evaluating of deep learning models on medical images
