L2R online:¶

• learn2reg.grand-challenge.org (This page) provides all information about the current Learn2Reg-Challenge, as well as our support forum and challenge archives
• github.com/MDL-UzL/L2R provides code for evaluation, zero-deformation fields for sanity checks and other useful utilities for developing your image registration algorithm.

Motivation:¶

Standardised benchmark for the best conventional and learning-based medical registration methods:

• Analyse accuracy, robustness and speed on complementary tasks for clinical impact. 
• Remove entry barriers for new teams with expertise in deep learning but not necessarily registration.

Learn2Reg removes pitfalls for learning and applying transformations by providing:

• python evaluation code for voxel displacement fields and open-source code all evaluation metrics
• anatomical segmentation labels, manual landmarks, masks and keypoint correspondences for deep learning

Learn2Reg addresses four of the imminent challenges of medical image registration:

• learning from relatively small datasets
• estimating large deformations
• dealing with multi-modal scans
• learning from noisy annotations

Evaluation: Comprehensive and fair evaluation criteria that include:

• Dice/surface distance and TRE to measure accuracy and robustness of transferring anatomical annotations 
• standard deviation and extreme values of Jacobian determinant to promote plausible deformations,
• low computation time for easier clinical translation evaluated using docker containers on GPUs provided by organisers.
