Fig. 3From: Insight to Nanoparticle Size Analysis—Novel and Convenient Image Analysis Method Versus Conventional TechniquesThe particle analysis of silver nanoparticles is problematic by traditional image analysis program: (a) the original TEM image, (b) the image threshold set into an optimum level to distinguish the background and the particles, (c) after optimal thresholding, the program does not distinguish the actual individual particlesBack to article page
