Arbicon-Net: Arbitrary Continuous Geometric Transformation Networks for Image Registration

1 code implementation NeurIPS 2019 Jianchun Chen, Lingjing Wang, Xiang Li, Yi Fang

To address this issue, we present an end-to-end trainable deep neural networks, named Arbitrary Continuous Geometric Transformation Networks (Arbicon-Net), to directly predict the dense displacement field for pairwise image alignment.

Coherent Point Drift Networks: Unsupervised Learning of Non-Rigid Point Set Registration

3 code implementations7 Jun 2019 Lingjing Wang, Xiang Li, Jianchun Chen, Yi Fang

In contrast to previous efforts (e. g. coherent point drift), CPD-Net can learn displacement field function to estimate geometric transformation from a training dataset, consequently, to predict the desired geometric transformation for the alignment of previously unseen pairs without any additional iterative optimization process.

Non-Rigid Point Set Registration Networks

1 code implementation2 Apr 2019 Lingjing Wang, Jianchun Chen, Xiang Li, Yi Fang

In contrast, the proposed point registration neural network (PR-Net) actively learns the registration pattern as a parametric function from a training dataset, consequently predict the desired geometric transformation to align a pair of point sets.
