Self-Supervised Multi-Object Tracking with Path Consistency

1 code implementation8 Apr 2024 Zijia Lu, Bing Shuai, Yanbei Chen, Zhenlin Xu, Davide Modolo

In this paper, we propose a novel concept of path consistency to learn robust object matching without using manual object identity supervision.

Compositional Generalization in Unsupervised Compositional Representation Learning: A Study on Disentanglement and Emergent Language

no code implementations2 Oct 2022 Zhenlin Xu, Marc Niethammer, Colin Raffel

In hopes of enabling compositional generalization, various unsupervised learning algorithms have been proposed with inductive biases that aim to induce compositional structure in learned representations (e. g. disentangled representation and emergent language learning).

iSegFormer: Interactive Segmentation via Transformers with Application to 3D Knee MR Images

1 code implementation21 Dec 2021 Qin Liu, Zhenlin Xu, Yining Jiao, Marc Niethammer

We propose iSegFormer, a memory-efficient transformer that combines a Swin transformer with a lightweight multilayer perceptron (MLP) decoder.

A Deep Network for Joint Registration and Reconstruction of Images with Pathologies

no code implementations17 Aug 2020 Xu Han, Zhengyang Shen, Zhenlin Xu, Spyridon Bakas, Hamed Akbari, Michel Bilello, Christos Davatzikos, Marc Niethammer

They are therefore not designed for the registration of images with strong pathologies for example in the context of brain tumors, and traumatic brain injuries.

Robust and Generalizable Visual Representation Learning via Random Convolutions

2 code implementations ICLR 2021 Zhenlin Xu, Deyi Liu, Junlin Yang, Colin Raffel, Marc Niethammer

In this work, we show that the robustness of neural networks can be greatly improved through the use of random convolutions as data augmentation.

DeepAtlas: Joint Semi-Supervised Learning of Image Registration and Segmentation

1 code implementation17 Apr 2019 Zhenlin Xu, Marc Niethammer

Specifically, in a one-shot-scenario (with only one manually labeled image) our approach increases Dice scores (%) over an unsupervised registration network by 2. 7 and 1. 8 on the knee and brain images respectively.

Networks for Joint Affine and Non-parametric Image Registration

2 code implementations CVPR 2019 Zhengyang Shen, Xu Han, Zhenlin Xu, Marc Niethammer

In contrast to existing approaches, our framework combines two registration methods: an affine registration and a vector momentum-parameterized stationary velocity field (vSVF) model.
