Multifractal filtering method for extraction of ocean eddies from remotely sensed image

Traditional methods to extract ocean wave eddy information from remotely sensed image mainly use the edge detection technique such as Canny and Hough operators. However, due to the complexities of ocean eddies and image itself, it is sometimes difficult to successfully detect ocean eddies using these types of methods. In this paper, a multifractal filtering technique is proposed for extraction of ocean eddies and it was demonstrated using NASA SeaWiFS satellite data set. The study area is located in the Gulf Stream of the North Atlantic. The result has demonstrated that the new method has a superior performance over the other traditional methods
