The imaging group focuses on bio-imaging, image analysis and visualization.

In this research group, led by Dr. Joost Beltman, the aim is to employ mathematical and computational dynamical modelling approaches in order to quantitatively and mechanistically understand the dynamical behaviour and regulation of intracellular networks of genes, proteins and metabolites as well as…

The rapid advances in imaging technology enable to see inside the body with ever increasing detail.

A computer can look at, and learn from, many more images than a human specialist. AI systems are rapidly becoming indispensable for medical and biological applications. But they still have to learn how to explain their decisions.

To study how planetary systems come into existence we study much younger systems still in formation.

This specialisation focuses on two important trends in health care: early diagnosis and developing the most targeted patient-specific treatment possible with the shortest possible recovery time and minimal side effects.

On the basis of the characteristic aspects of a picture, certain computers can tell us what the picture is showing. They can learn this in the same way that young children are able to learn to recognize images. Further improving these techniques opens the way to a whole range of new applications. Biology…

Image segmentation is a fundamental task in computer vision, with applications ranging from medical diagnostics to archaeological research.

In this project we develop algorithms to automatically detect a particular type of archaeological sites in satellite images of the Alps.

Optical projection tomography (OPT) is a tomographic 3D imaging technique used for specimens in the millimetre scale.

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

How and to what extent the historic house (re-)constructs identity through image-making in China.

This thesis mainly focuses on cross-modal retrieval and single-modal image retrieval via deep learning methods, i.e. by using deep convolutional neural networks.

This thesis focuses on the study of transient and variable radio sources in the universe.

From surface science towards industrial practice using high-pressure scanning tunneling microscopy.

One of the ways of understanding another culture better is to examine what people experience when they read a text, or look at an image. Leiden experts have a lot of knowledge in this field, for example on culture in ancient Japan.

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

Zebrafish is an excellent model organism for studying various human diseases. Due to opaqueness of the adult phase, in vivo studies are restricted to early embryonic stages. This raises the need for rapid sensitive and non-invasive in vivo imaging methods to follow developmental processes, not only…

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

On June 3rd at 10:15, Kay Boers (Utrecht University) will defend his PhD thesis, titled "CIVIS: Rhetoricity, Citizens, and Citizenship in Seventh-Century Hispania." The defense will take place in the Senaatszaal of the Academy Building of Utrecht University (Domplein 29).

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

The aim of this project is to study what makes an act or form of violence a specifically political reality.

The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.
