Tiling artifacts and trade-offs of feature normalization in the segmentation of large biological images

Authors Buglakova E, Archit A, D’Imprima E, Mahamid J, Pape C, Kreshuk A Journal Arxiv Citation arXiv:2503.19545. Abstract Segmentation of very large images is a common problem in microscopy, medical imaging or remote sensing. The problem is usually addressed by sliding window inference, which can theoretically lead to seamlessly stitched

PHluorin-conjugated secondary nanobodies as a tool for measuring synaptic vesicle exo- and endocytosis

Authors Georgiev SV, Rizzoli SO Journal Scientific Reports Citation Sci Rep 15, 10093 (2025). Abstract Neuronal communication relies on synaptic vesicle recycling, which has long been investigated by live imaging approaches. Synapto-pHluorins, genetically encoded reporters that incorporate a pH-sensitive variant of GFP within the lumen of the synaptic vesicle, have
