The <t>SIMPoly</t> algorithm includes an initial built-in step that uses the SEM micrograph scale bar to convert pixels to micrometers. This allows fiber diameter measurements to be output in microns. If the micrometer/pixel ratio is already known, it can be entered without measurement of the scale bar, or if it is unknown but there is no scale bar, the output will be in pixels.

Techniques:

Bar graph displaying the average fiber diameter measurements made by each researcher using each of the three analysis methods (manual ImageJ, DiameterJ, and Matlab-based SIMPoly) for the PLGA nanofiber images. Although there is no known “true” fiber size for these samples, the new Matlab-based SIMPoly method provided appropriate fiber diameter measurements, as compared with the more well-established manual and DiameterJ approaches, and the SIMPoly method had the least variation between researchers. Color images are available online.
