Super-Resolution from a Single Frame
Published:
Standard SOFI needs hundreds of frames of blinking emitters to beat the diffraction limit. You acquire a long temporal stack, compute cumulants across time, and the nonlinear statistics sharpen the point spread function beyond what any single exposure can resolve. It works beautifully, but it demands fluorophores that blink stochastically, and it demands patience while you collect enough frames for the statistics to converge.
