EstimationTool

Single-molecule parameter estimation

The ability to localize/resolve single molecules continues to play a key role in single molecule data analysis. The EstimationTool allows a user to perform localization and resolution estimation tasks on images of fluorescent objects (like single molecules, vesicles, etc.). It offers various choices of estimators (non-linear least squares estimator, maximum liklihood estimator, etc.), various choices of point spread functions (Airy point spread function, Born-Wolf point spread function, Gibson-Lanni point spread function, etc.) with which to fit the data. Users can customize virtually every aspect of the localization/resolution task. The localization/resolution results can be exported for further applications like tracking or diffusion coefficient calculations.
