Abstract

Abstract

Traditional methods to extract ocean wave eddy information from remotely sensed imagery mainly use the edge detection technology such as Canny and Hough operators.However, owing to the complexities of ocean eddies and imagest hemselves, it is sometimes difficult to successfully detect ocean eddiesusing these methods.A multifractal filtering technology is proposed for the extraction of ocean eddies and demonst rated using NASA MODIS, SeaWiFS and NOAA satellite data set in the typical area, such as western boundary current.Results are demonst rated that the new method has a superior performance over the traditional methods.
