ABSTRACT
In this chapter, a new distance transform method for measuring fiber diameter in electrospun nanofiber webs has been described. In this algorithm, the effect of intersection has been eliminated which brings more accuracy to the measurement. The effectiveness of the method was evaluated by a series of simulated images with known characteristics, as well as some real webs obtained from electrospinning of PVA. The new method was then compared with the original distance transform method. The results obtained by the new method were significantly superior than the distance transform, indicating that the new method could successfully be used to measure electrospun fiber diameter. Figure 7.1 illustrates the electrospinning setup.
