Abstract :
The U.S. National Ice Center requires a robust multiyear ice classification algorithm that can handle variability in backscatter across uncalibrated 500 km RADARSAT scenes. ERS-1 images are used to test a dynamic threshold algorithm. The best results were obtained with a window size of 32, delta of 0.8, Fisher partition criterion and closing
