Creating a deep learning network for image registration is complex because humans can’t easily prepare or supervise the training data unless it’s very basic. The initial developments, such as ResNet-based and U-Net-based networks, laid the groundwork for deep learning-driven image registration. Generally, two kinds of guidance can be applied to train the non-rigid registration network: (1) using the “ground - truth” transformation fields [ 3 ], or (2) guided by image similarity metrics To conclude, we propose an unsupervised deep learning-based image registration framework dedicated to histology images acquired using different stains.
