Low-complexity learning for large-scale imaging

Status: active (Ziwen Wang) Description: Model-based deep learning refers to a new family of methods that integrate both physics-based and trainable parameters within a single neural network. For many large-scale applications, computing gradients of such networks via backpropagation is infeasible due to the memory limitations of GPUs. This project seeks to address this issue by designing memory-efficient architectures obtained by trading off computation storage and computational complexity. We will consider large-scale biomedical imaging applications. Supervision: Jiaming Liu (jiaming.liu@wustl.edu), Ulugbek Kamilov Areas: Deep Learning, Algorithm Design

Tunable deep learning for computational imaging

Status: active (Ann Zhou) Description: Deep learning has led to a paradigm shift in computational imaging. In this project, we will explore the topic of tunable deep learning, where the goal is to design techniques that enable us to adjust convolutional neural networks without retraining them. We will explore the applications of the techniques in biomedical imaging. Supervision: Xiaojian Xu (xiaojianxu@wustl.edu), Ulugbek Kamilov Areas: Deep Learning, Image Restoration

Synthesizing high-resolution videos using deep learning

Status: active (Wentao Shangguan) Description: Video reconstruction is aimed to restore clear videos from corrupted observations, where state-of-the-art methods have achieved promising performance via supervised deep learning technologies. However, those methods require ground-truth videos, which may be inaccessible in some cases. Our goal is to develop a novel video reconstruction algorithm without the need of ground-truth.

Accurate calibration of coil sensitivities in MRI

Status: active (Yuyang Hu) Description: Parallel MR image reconstruction yields optimal results when the coil sensitivity maps are accurately known. Unfortunately, in practical scenarios, obtaining accurate estimates of the sensitivity maps is not possible. In this project, we explore the potential of deep learning to enable accurate estimation of coil sensitivity maps.
