Sh. Peckinpaugh et Rj. Holyer, CIRCLE DETECTION FOR EXTRACTING EDDY SIZE AND POSITION FROM SATELLITEIMAGERY OF THE OCEAN, IEEE transactions on geoscience and remote sensing, 32(2), 1994, pp. 267-273
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.
