Title: Image decomposition in Fluorescence Microscopy: A posterior sampling based approach
Abstract: Fluorescence microscopy faces limitations due to the microscope’s optics, fluorophore chemistry, and photon exposure limits. This necessitates trade-offs in imaging speed, resolution, and depth. In my talk, I will discuss the two deep-learning-based computational multiplexing techniques [AKDS+23, AJ24], and their application [ACZ+25] which we developed during my PhD that enhanced the imaging of multiple cellular structures within a single fluorescent channel, allowing faster imaging and reduced photon exposure. Given a superimposed image (say containing Nucleus and Tubulin), my PhD research is to predict its constituent images separately. Our approach can sample diverse predictions from a trained posterior and is GPU-efficient. At last, I will end my talk with our ongoing work on creating an approach which can handle different levels of superposition
