| Abstract: | Accurate and real-time measurement of sea surface currents is significant for the study of physical oceanography.The block matching algorithm of maximum cross-correlation (MCC) is presented in detail in the paper,and sea surface currents can be obtained by analyzing ocean color remote sensing images with MCC algorithm.To improve the accuracy,the sub-pixel operation is applied to the MCC results.The reliability can be verified by the measurement of the Tsushima Strait sea area. |
