Abstract
The images from the scanning tunneling microscope (STM) can be improved with digital filtering using the fast Fourier transform. In this communication we discuss the noise characteristics for images taken in air with the STM. The STM images are significantly enhanced if we assume the noise has an 1/f characteristic and use a Weiner optimal filter to remove this type of noise.This publication has 2 references indexed in Scilit:
