Abstract
Abstract An image analysis measurement system is capable of performing a variety of measurements on single features within a field of scan or independently on multiple features within the field. The system provides direct determination of measurements across multiple features in the field for specific parameters. The measurements include, for example, projected length in any direction, perimeter, Feret's diameter in any direction, longest dimension, convex perimeter, and breadth.
