“…As an example, he shows that the different possible representations of a multivalued image can be used as alternatives to standard techniques for multivariate statistical analysis. Hawkes (1995aHawkes ( , 1998) presents a review of image algebra for electron images and shows that all known image processing operations (divided into four classes: image acquisition and coding, enhancement, restoration and analysis) can be described using the framework and notations of image algebra. Hawkes (1995b) shows that the very specific images which can be recorded with a STEM are in fact templates and can be processed as such within the framework of image algebra.…”
