Abstract
This paper evaluates the ability of several circle detectors to define the size and position of warm and cold eddies in oceanographic satell ite imagery. The Advanced Very High Resolution Radiometer channel 4 (1 0.3-11.3 mum) or sea surface temperature test images are reduced to bi nary edge images. Six different circle detectors are then applied to t he edge images. The automated results are compared to eddies defined b y a trained analyst.
