Monday is the start of the summer school in #digital #palaeography which I run in Göttingen every summer. We have 16 amazing international students and 2 weeks to play with #medieval fragments, #multispectral imaging, network analysis, bookbindings, biocodicology and much much more, topped off by a trip to the fabulous @hab_wf and a hackathon. It's the absolute highlight of my year. Follow this year's posts and photos via #SummerSchool25. @histodons @medievodons @historikerinnen

Over the past week, we've conducted drone surveys at archaeological sites in Sinarcas, Caudete de las Fuentes, Ademuz, and Moixent, using #multispectral and #LiDAR sensors. A big thank you to the #NTNU University Museum for their invaluable support, particularly to Professor Ole Risbøl and Magnar Mojaren Gran for their expertise. Through this collaboration, we’ve had the opportunity to learn from their extensive knowledge, enhancing our skills and understanding while working with these methods.
[New Video] Real-time Human Detection with 4-Band Raspberry Pi Camera
Check out our new demo video showing real-time human detection using a 4-Band Raspberry Pi Camera! The video displays the camera's view along with inference results highlighting detected humans.

Revealing #palimpest with #multispectral #imaging! These amazing results, showing a #Merovingian overtext and a 5th-century Gospel undertext, were achieved by my colleague Alex Zawacki at Göttingen. I'll be presenting the full results of this and other cool discoveries in May at a German-language conference in Kiel.
A false-color #multispectral photo I took of a larkspur with UV and IR light mapped on top of a regular visible-color photo. Inner parts of the flower petals reflect more UV than others and thus show up in blue. Other parts absorb UV but reflect IR, resulting in the red colors seen in the inner part of the flower and stems. Many flowers use this contrast to help pollinators (who often can see UV) to distinguish key parts of the flower.

My first image from my hacked-together #multispectral (IR, UV, and visible light) camera. Near IR is in red, visible light is in green, and UV is in blue.
The camera itself is a monochrome camera I normally use for solar imaging, while the lens is just a regular Nikon 50 f/1.8D. Between the two is an electronic filter wheel with IR pass, IR cut, and UV pass filters.

Zum Ende meines Bibliotheksreferendariats habe ich vier Wochen lang das Handschriftenzentrum an der @ubleipzig kennengelernt. Inklusive war die Teilnahme am „9. Alfried Krupp-Sommerkurs für Handschriftenkultur“, in dem auch #multispectral #imaging zum Einsatz kam. Danke an das tolle Team für eine schöne Zeit

Do you (or someone you know) have a DJI Mavic 3M and can support #opensource by offering up an image set to help the @OpenDroneMap team complete new feature testing?

OpenDroneMap Community · Call for DJI Mavic 3M datasetsWe’re working through getting band alignment working on DJI Mavic 3M datasets. Thanks to different hardware / firmware, etc., we cannot necessarily know the changes in tagging between versions, and the tagging is critical for getting the correction parameters for aligning the bands. So: if you have a DJI Mavic 3M dataset or a few to share, please reach out, either in this thread of in DM if it’s more sensitive. The results so far are promising:

I should also say that @InsularMSS will involve not only #medieval #manuscript studies but also #digitalhumanities and scientific research: palaeoproteomics, #multispectral and photometric stereo #imaging, handwritten text recognition (#HTR), Raman and XRF #spectroscopy, infra-red #microscopy & much more. Perhaps most important, though, will be the freedom and time to do this important work!
