A texture based image processing algorithm for nanoparticles analysis

This paper describes an algorithm based on the two-dimensional Hurst operator for detecting edges and characterizing texture and distribution information in nanoparticle images obtained using a Transmission Electron Microscope. Results using this technique are shown for several types of nanoparticles including nearly spherical and more irregularly shaped nanoparticles. The results obtained suggest good performance; with further refinements the algorithm may provide a useful tool for nanoparticle research.
