Radar Image Segmentation Using Active Contour Method

Recently, active contour method has been widely applied on image processing in seeking the edges or contours of desired features. Active contour is the procedure to deform an initial given curve so that a designed functional of the curve will reach a local minimum. We introduce a new energy functional that involves the maximal intensity of image and a flexible parameter. By minimizing such energy functional and optimizing the parameter in the functional, the edge of desired feature can be found. This method has been applied on weather radar reflectivity fields to segment weather echoes from clear air echoes. Some preliminary results will be presented in the conference.
