CENTRIA - Departamento Informática, Faculdade Ciências e Tecnologia, Universidade Nova Lisboa, Quinta da Torre, Caparica 2829-516, Portugal.
A new machine learning approach is presented for automatic detection of Mediterranean water eddies from sea surface temperature maps of the Atlantic Ocean. A pre-processing step calculates the direction of the temperature gradient at each point of the map. Given a map point, information on the surrounding thermal gradient field is extracted through a binary mask and organised as a numerical vector of gradient angles. This vector is forwarded to a multi-layer perceptron classifier that ...
