Abstract

Ellipse detection has been presented in scientific literature as a potential method for finding eddies in satellite images because eddies may be roughly approximated by ellipses. In the present work, therefore, we describe a method to identify eddies based on ellipse center detection. The centers are determined using ellipse fitting. The proposed method allows finding several eddies per satellite image, an ability not demonstrated by previously reported eddy detectors based on ellipse recognition in binary images. The low values of the temperature gradients off the Iberian Peninsula complicate the application of the detection method because they raise difficulties in the creation of binary images with proper eddy outline. Most algorithms previously reported in the scientific literature are not applicable to the present case.
