Abstract :
The algorithm for separating Baltic Sea Ice and open water from our operational SAR data are presented. The algorithm is based on segment wise autocorrelation with some simple additional rules to improve the classification. The algorithm results are compared to the open water and sea ice separation available in daily digitized ice charts and the algorithm performance is also compared to open water detection by pixel-wise autocorrelation thresholding
