Summary: IEEE TRANSACTIONS ON INSTRUMENTATION AND MEASUREMENT, VOL. 48, NO. 1, FEBRUARY 1999 55
Identification and Measurement of Fibers
in Scanning Electron Microscopy Images
Using a High-Order Correlation Process
Oscar YŽa~nez-SuŽarez, Member, IEEE, and Mahmood R. Azimi-Sadjadi, Senior Member, IEEE
Abstract--This work describes the development of a dedicated
system capable of identifying, measuring and counting various
types of fibers and other objects in digitized scanning electron
micrograph (SEM) imagery. The system uses a recursive high
order correlation (HOC) process to extract the corner pixels of
the fibers. The objects are defined by grouping connected corners,
so that morphometric analysis can be performed. The method
developed performs satisfactorily when the density of fibers per
image ranges from low to medium. Simulation results for several
cases are presented, along with a discussion on the capabilities
and limitations of the current version of the system.
Index Terms-- Fiberglass identification, image analysis, mea-
surement technology.
