WebSep 1, 2024 · The developed classifier with best performance used a combination of the GLCM mean texture feature and VH intensity. Rubble ice has high GLCM mean and VH intensity values, because of the homogenously high VV backscatter and a large amount of depolarization. The GLCM mean of sheet ice is consistently lower than for rubble ice.
