Tools & Resources, from the Community, for the Community

In this section, we highlight open and practical tools, resources, and solutions developed across the imaging community. Here is this issue’s selection:

Tool spotlight: GloViTa

GloViTA logo

Got a pile of images, scans, or video clips and a question like “which category is this?” or “how severe is this?”, but no interest in building a training pipeline from scratch? That’s the gap GloViTa is meant to fill.

GloViTa is a reusable framework for training deep learning models on classification and regression tasks — and it doesn’t care what field the images come from. Microscopy, satellite imagery, medical scans, wildlife camera traps, industrial inspection photos, pathology slides: as long as the task is “look at this and predict something about it,” the same framework applies. 

It supports 2D images, 3D volumes, video, and bag-of-patches setups like whole-slide pathology images. Instead of writing a new script for every project, you set a few basic options — where your data lives, how many classes you’re predicting, which pretrained model to start from — and run one command. It takes care of loading the data, training, and validating, and it automatically saves the exact settings used for each run, so results stay traceable later on.

A solid starting point if imaging AI keeps showing up in your work, regardless of domain, and you’d rather not reinvent the training loop each time.

Have a tool, dataset, software package, or other resource you’d like to share? Submit your solution via CONNECT and help grow the collection of open and easy-to-use imaging resources. We look forward to featuring more community-driven tools in upcoming issues!

Welcome to the team, Karan and Nick

We are happy to welcome Karan Mahajan, who joined our Helmholtz Imaging Support Hub as a Scientist in Visual Analytics for Earth System and Geospatial Data. Originally from India, Karan completed his M.Sc. in Environmental Engineering at the Technical University of Munich and has a background in water resources management, with a focus on (eco-)hydrological and flood modelling. His research interests lie at the intersection of machine learning and process-based modelling, particularly for improving the parametrization of land-surface processes. He also works with large-scale geospatial datasets and looks forward to further exploring these types of data in his new role.

Portrait of Karan Mahajan

“I really like the flexibility Helmholtz Imaging offers in choosing projects, as this facilitates flow of independent ideas that can come to fruition using the provided resources and network. Looking forward to meeting colleagues in the coming months and to exciting collaborations across the community.“

We are delighted to also have Nick Lechtenboerger on board as a PhD student at Helmholtz Imaging Research Unit at MDC. He recently completed his Master’s degree in Data Engineering at Hasso Plattner Institute (HPI), where he first started working on self-supervised learning (SSL) foundation models with Dagmar Kainmüller as part of a student project. Now, two years later, he is continuing this work in his PhD, focusing on advancing self-supervised learning for messy, real-world datasets. His research addresses open questions that arise when methods developed primarily on natural images and well-curated datasets are applied to more complex scientific data.

Portrait photo of Nick Lechtenboerger

“Current SSL algorithms make so many assumptions about the underlying data that pre-training on scientific data, such as plankton or microscopy images, becomes extremely difficult. However, I am confident that we can find more general algorithms that will enable domain scientists to make use of their large unlabelled datasets.“

A warm welcome to Karan and Nick! We look forward to working with you.
