An image-processing program for automated counting

January 1, 1996

An image-processing program developed by the National Institute of
Health, IMAGE, was modified in a cooperative project between remote sensing
specialists at the Ohio State University Center for Mapping and scientists at
the Alaska Science Center to facilitate estimating numbers of black brant
(Branta bernicla nigricans) in flocks at Izembek National Wildlife Refuge. The
modified program, DUCK HUNT, runs on Apple computers. Modifications provide
users with a pull down menu that optimizes image quality; identifies objects of
interest (e.g., brant) by spectral, morphometric, and spatial parameters defined
interactively by users; counts and labels objects of interest; and produces
summary tables. Images from digitized photography, videography, and high-
resolution digital photography have been used with this program to count various
species of waterfowl.
