Image processing for sequence of oceanographic images

Abstract : This paper is concemed with three main problems of image processing occuring on temporal sequences of satellite oceanographic images: approximate localization of the interesting structures on the images; segmentation or determination of the boundary of the structures; and temporal tracking of these boundaries to illustrate their evolution. ln this paper, application is done on vortices and results are displayed ail over the paper. For this purpose, we propose a new method for optical flow computation and interpretation and a geometric modeling of the structures. Oceanographic images obtained from environmental satellite platforms present a new challenge in computer science. The huge amount of data collected each day and the needs of characterizing some specific structures on these images for oceanographic monitoring justify our approach for the detection and tracking of vortices on oceanographic images.
