IMAGE: modified for use on a microcomputer-based system

Abstract

The previously published FORTRAN program IMAGE has been modified for use on a microcomputer. It has been translated into Turbo Pascal and an inexpensive tablet-type digitizer is used for input instead of a microdensitometer. This provides a readily affordable system for image analysis. The interactive nature of a tablet-type digitizer allows the operator to select what is to be digitized as the boundaries of a particle are traced. The parameters calculated for each particle remain the same as in the FORTRAN version but some parameters are derived in a different manner. The "best-fit" ellipse is constructed for each particle. © 1989.
