Brain segmentation based on multi-atlas guided 3D fully convolutional network ensembles [article]

Jiong Wu, Xiaoying Tang
2019 arXiv   pre-print
To reduce over-fitting of the FCN model on the training data, we adopted an ensemble strategy in the learning procedure.  ...  One major limitation of existing state-of-the-art 3D FCN segmentation models is that they often apply image patches of fixed size throughout training and testing, which may miss some complex tissue appearance  ...  In the multi-encoding part, the training image patch and the most similar atlas patches are separately learned.  ...

2018 arXiv   pre-print
Our algorithm detects corners by Harris and matches them by a patch-metric learned on top of CIFAR-10 network descriptor.  ...  Multi-modal images of the same scene capture different signals and therefore their registration is challenging and it is not solved by classic approaches.  ...  Given a VIS channel patch P v and a NIR patch P n we offer to learn a metric that measures the similarity distance between them.  ...
