Bridging from raw 3D EM data to more easily interpretable biological data.

node:body | entity_field

The COSEM Project Team at Janelia Research campus uses computer vision and machine learning techniques to scalably detect subcellular structures, such as organelles, in datasets generated with next-generation volumetric electron microscopy. 


Within Janelia are some of the world’s leading experts in Machine Learning (Saalfeld lab and Funke lab), Cell Biology (Lippincott-Schwartz lab), and large-volume, high-resolution EM data acquisition (Hess lab and FIB-SEM Technology Group). At their intersection lies a unique area of research. COSEM is expanding that intersect and driving forward our tools and knowledge with respect to identifying subcellular structures within EM data in an automated way. As a result, the products that COSEM provides includes quantitative analytics and data resources. It will allow us to reimagine our canonical textbook image of the inside of a cell and provide biological insight and knowledge and do this in a way that is open and accessible to the broader scientific community and public.

WholeCell_3D_600.jpgOur public repositories of raw datasets, training data, reconstructions, open source code, and models are an invitation to the scientific community to join our ongoing efforts to improve and further develop better and more robust automatic reconstruction and analysis methods for intra-cellular structures from FIB-SEM. We are optimistic that this will accelerate scientific discovery in both computational and biological domains leading to new and exciting insights and methods developments in the near future and beyond.
