Open projects

Robust fine-tuning of deep learning models for accelerated MRI reconstruction

We’re looking for a Master’s student to explore robust fine-tuning strategies for pre-trained deep learning models for accelerated MRI. While fine-tuning improves performance on the target dataset, it sacrifices robustness to out-of-distribution data. This project aims to better understand fine-tuning for image reconstruction and in particular accelerated MRI with the goal of proposing robust fine-tuning methods for accelerated MRI.
Supervisor: Kang Lin (
Prerequisites: Strong coding skills with PyTorch. A good understanding of deep learning frameworks.
Type of project: Masters thesis or Reserach Internship (Forschungspraxis)


Deep learning based fetal magnetocardiography system

We are looking for a Master’s student to work on deep learning based reconstruction for a fetal magnetocardiography system, in a interdisciplinary collaboration with Prof. Fierlinger and Prof. Wacker-Gussmann. The goal of the thesis is to develop deep learning based signal reconstruction techniques for this new medical imaging and sensing technology.
Supervisor: Reinhard Heckel, Kang Lin
Prerequisites: Strong coding skills, specially in pytorch. A good understanding of deep learning for inverse problems.
Type of project: Masters thesis

Learning a full camera pipeline

A camera’s image processing pipeline usually consists of many different image processing modules, e.g. debayering, denoising, filtering. Many of these steps rely on measurements that enable some parameter settings, that are used in a part of the image pipeline. Successful learning-based approaches like the approach of “Learning to see in the dark” present a different approach to obtain a high-quality image by learning the full camera pipeline. While the work in this paper uses a convolutional network, transformer-based approaches including an attention mechanism are have shown greater success on image processing tasks recently. This student project investigates the possibility of learning a full camera pipeline for real camera data based on fusion of classical and learning based approaches to find the optimal tradeoff between state-of-the-art image quality and efficiency on a real camera hardware.
Supervisor: This project is supervised by Dr. Seybold at ARRI and carried out at ARRI, the supervision from the TUM side is by Reinhard Heckel.
Prerequisites: Coding skills, interest in imaging and signal processing.
Type of project: Details of the scope can be adjusted to the kind of thesis (Bachelor thesis, Master thesis, research internship)


Self-supervised reconstruction of PET Scans

We are looking for a Master's student to work on reconstructing PET scans using self-supervised deep learning techniques. Since obtaining ground truth PET images is difficult and expensive, self-supervised training has emerged as a useful tool. In other medical image domains such as CT and MRI self-supervised techniques have proven to be successful. Our aim is to test those techniques on PET imaging. To learn more about the project, please contact Youssef Mansour.
Supervisor: Youssef Mansour (
Prerequisites: Strong coding skills, specially in pytorch. A good understanding of deep learning for inverse problems.
Type of project: Masters thesis


A Test-Time-Training Approach for Image Denoising under Distirbution Shifts

We are looking for a Master's student to work on a project of improving a method that finetunes a trained model at test time to adapt to different distribution shifts for image denoising. The different shifts include natural and medical images, synthetic noise, and real-world camera and microscope noise. Your task is to understand and reproduce the method as as well adding ablation studies and extra comparisons with other baselines. You will also contribute to improving the performance of the method, and making it more intuitive. To learn more about the project, please contact Youssef Mansour.
Supervisor: Youssef Mansour (
Prerequisites: Strong coding skills, specially in pytorch. A good understanding of deep learning frameworks. Interest in collaborative work.
Type of project: Masters thesis or Reserach Internship (Forschungspraxis)


Estimating the age of a DNA sample from sequencing data 

We are looking for a Master’s student to develop, implement, and test an idea to estimate the age of a given DNA sample from sequencing data alone. First you would perform literature research on existing approaches and then implement and test a few concrete ideas in python.
Supervisor: Reinhard Heckel (
Prerequisites: Interest in interdisciplinary work and data analysis.
Type of project: Masters thesis


Cardiac magnetic resonance imaging with neural networks 

We’re looking for a Master’s student to work on a new deep neural network based method for imaging a non-static object, specifically a beating heart. You would implement an idea for a neural network based method in pytorch, evaluate the method on real data within a collaboration with the University Hospital, and there is also room for developing your own ideas.
Supervisor: Reinhard Heckel (
Prerequisites: Ideally knowledge of deep learning for inverse problems and python and pytorch programming experience.
Type of project: Masters thesis
