Serena Yeung - Computer Vision for Segmenting & Analyzing Subcellular Components in CE Tomography

Presenter
November 15, 2022
Abstract
Recorded 15 November 2022. Serena Yeung of Stanford University presents "Developing Computer Vision Methods for Segmenting and Analyzing Subcellular Components in Cryo-Electron Tomography" at IPAM's Cryo-Electron Microscopy and Beyond Workshop. Abstract: CryoET technology is generating significant amounts of 3D tomogram data containing rich information about subcellular components, their structural appearance, and interactions. However, analysis of this data through manual annotation is very time-consuming, while the 3D nature of the data poses challenges for automated, machine learning-based feature segmentation and analysis. In this talk, I will present work on developing computer vision methods for automated segmentation of features in cryoET tomograms. I will discuss our computer vision approach for 3D segmentation and analysis of mitochondrial volumes and granules in iPSC-derived neurons differentiated from Huntington's Disease patient samples. I will additionally present ongoing work on developing methods for increasingly label-efficient segmentation of features, that can enable scaling computer vision analysis of 3D tomograms to significantly larger numbers of features.
