title: A low-cost image analysis system for scanning transmission electron microscopy low-dose images.
abstract: An image processing system is described which has been used to analyze STEM images of biological macromolecules. The system has the inherent virtues of being inexpensive, easy to program and self-contained. The operating procedures are described using a particular molecule (earthworm hemoglobin) as an example. We show the versatility of the system by describing addition, Fourier filtration, background subtraction, gray-scale expansion, y-deflection, and contouring of images. Color images are also produced but cannot be reproduced here.
