Automatic Detection of Gulf Stream Rings.
Melvin F. Janowitz · Defense Technical Information Center (DTIC) · 1985
A prototype for a program for the automatic detection of Gulf Stream rings from satellite IR images is described and illustrated. It includes a comparative study of 40 different filters on real data. The program involves a number of components: image smoothing, image simplification, edge detection, removal of small objects, and ellipse detection. (Author)
