Size Measurement of Nanoparticle Assembly Using Multilevel Segmented TEM Images

Figure 1

Detection of nanoparticles by thresholding method and -means: (a) result obtained by the Canny operator, (b) result obtained by Otsu’s threshold and the Canny operator, (c) result obtained by -means, and (d) original image superimposed with the detected edge. The final two cases show increased structural resolution and association in a manner that appears more perceptually relevant.
