Abstract

The Fry method is a very powerful way to determine the finite strain ellipse in a deformed rock, but the problems of reproducibility and objectivity of the measurements still remain. Using image processing, the program presented here extracts the central void from Normalized Fry diagrams and computes the characteristics of the best fitted ellipse. It runs automatically on Personal Computers, but remains interactive with the operator, as does the videographic image analyzer.
