Prompt-Tuning SAM: From Generalist to Specialist with only 2048 Parameters and 16 Training Images

Tristan Piater, Björn Barz, Alexander Freytag

The Segment Anything Model (SAM) is widely used for segmenting a diverse range of objects in natural images from simple user prompts like points or bounding boxes. However, SAM's p…

Intra-operative Brain Tumor Detection with Deep Learning-Optimized Hyperspectral Imaging

Tommaso Giannantonio, Anna Alperovich, Piercosimo Semeraro +9

Surgery for gliomas (intrinsic brain tumors), especially when low-grade, is challenging due to the infiltrative nature of the lesion. Currently, no real-time, intra-operative, labe…
