摘要：In this paper, the existence of mesoscale eddy is confirmed by comparing the data of historical earth transfer with the eddy found in historical SAR images. The eddy phenomena in SAR images were identified by multi-region segmentation and direction detection. The structure characteristics of eddy edges were extracted and the center position of mesoscale eddy was estimated by edge characteristics. The effectiveness of the proposed method is verified by comparing it with the data of ground transfer.
