Last day of a fantastic #ecvp2026! 🎉 I’m excited to present my most recent work at 10:30am in Bayview. I’ll argue that eye movements are a crucial part of the visual input itself, and that we naturally use them to optimally encode relevant stimulus properties Hope to see you there! 👀

TU Darmstadt's Perception Lab is at #ECVP2026 in force. We hope you can make it to see our work! @engramm.ing @lreining.bsky.social @lschmittwilken.bsky.social

New preprint! Have you ever wanted to measure psychometric functions in high-dimensional stimulus spaces, but realised that this is infeasible? We present and validate a technique to adaptively estimate psychometric functions for stimulus spaces up to 50 dimensions. www.biorxiv.org/content/10.6...

Adaptive experiments in high-dimensional feature spaces: A particle filtering approach

Behavioral experiments are often infeasible when stimulus spaces have many dimensions or when testing time is limited. One way to address this challenge is adaptive stimulus selection, where informati...

So happy to see this published! 🎉 Meet **deadleaves**, an #OpenScience Python package for generating Dead Leaves images to study #vision, segmentation, natural image statistics, and beyond. 📄 Paper (JOSS): doi.org/10.21105/jos... 📚 Documentation: deadleaves.readthedocs.io For more info 🧵

The final Glushko Dissertation Prize talk features Lynn Schmittwilken @lschmittwilken.bsky.social, who examines how the tiny movements our eyes make continuously shape visual perception from its earliest moments. #CogSci2026

I'm incredibly honored to have been awarded the Glushko Dissertation Award! 🎓 Thanks to everyone who supported me along the way. If you're at #CogSci2026 in Rio 🇧🇷, I'll be presenting on Saturday at 12:25PM. I'd love to see familiar faces and meet new ones; excited for some great discussions!

Curious how tiny eye movements shape the visual input? Our new paper integrates spatiotemporal encoding into the standard model of #earlyvision. We suggest that models may be biased towards purely spatial perspectives—inviting us to rethink our view on early visual mechanisms doi.org/10.1167/jov....

Very excited to have @lschmittwilken.bsky.social start today as a postdoc in my lab! If today’s heatwave in Darmstadt is any indication, be prepared for some 🔥 work coming out of this collaboration in the future!

Not tired of talking science yet? Come visit me at 2.45pm in Banyan to learn how we used #drawing to probe #earlyvision in natural scenes. With this approach, we reproduce traditional psychophysics measures, while preserving a rich behavioral dataset for additional analyses #vss #vss2025

Sorry for the spam! Someone recommended a tool to import a selection of X tweets, which turned out to be a horrible idea 🙏🏽

Not tired yet of talking science? Then come visit me at my poster this morning (Mo, 8.30-12.30; Pavilion) to learn about a new #fovealPerimetry that provides new and unexpected insights into visual sensitivity patterns at the foveal scale #vss #vss2024 https://t.co/PxnSwvGI5g

First and foremost, you can find all information about stimupy, what it contains, how to install and use it, and how to contribute to the project here: https://t.co/5M0xx8OidO

So proud to see this published. Discover stimupy – an #openscience Python package to support and automatize creating visual stimuli as used in the study of (early) #visualprocessing. Useful for #psychophysics, computational modeling, and teaching. For details, see this 🧵 https://t.co/KFqwt1cD2b

I hope everyone is having a blast at #vss2023! Consider visiting us at (1) our demo in which you can explore how #stimupy can help you with generating visual stimuli, and (2) our poster in which we ask how edge sensitivity is different from sinusoidal contrast sensitivity. 🧵

Hard to believe that my first week as the newest member of @aplabUR @UofR is coming to an end. Thanks to everyone in- and off-campus for the warm welcome and for all the new, exciting insights! Looking forward to be working with my new amazing colleagues in the year to come🤓

Very excited to give a talk at #ecvp2022 (5pm, Object Perception I) about a very exploratory project in which we wanted to see how re-thinking our idea of retinal images might affect information processing in CNNs (... yes, there will be images of cats and dogs🐈‍⬛🐕) https://t.co/nsla0bdAOx

First day of #ecvp2022! I am excited to give a tutorial together with @JorisVincent focusing on how spectral analysis is a relevant tool for vision scientists. If you cannot make it to the workshop, you can explore all the materials interactively here: https://t.co/BGriSpOBmM

Very excited to see my first PhD-related paper being published 🎓 We propose an active model of human edge perception in which edges emerge as a direct consequence of small ocular drift motions and the spatiotemporal sensitivity of the visual system. Check this 🧵 for more info https://t.co/BBfmV3iQMb

Only two more days until #VSS2021. If you are curious about #activevision and how fixational eye movements could contribute to human #EdgeDetection and lightness perception, come and visit me at my poster I43 (Wed 8:00 am EDT | 2:00 pm CEST, Manatee) https://t.co/aJme2qdwHw
