MARC recordImage analysis of sea-ice thin sections: a step towards automated texture classification / Hajo Eicken, Manfred A. Lange.
| Title: | Image analysis of sea-ice thin sections: a step towards automated texture classification / Hajo Eicken, Manfred A. Lange. |
| Author(s): | Eicken, Hajo. Lange, Manfred A. |
| Date: | 1991. |
| In: | Annals of Glaciology. (1991.), Vol. 15 (1991) |
| Abstract: | Describes development of technique that permits differentiation between granular, columnar, and mixed-type sea ice. Thin sections of ice between two polarizers are photographed and then pixel-processed on PC for contrast properties. Two parameters, "contrast gradient" between grains and skewness of cord-size (i.e. length of perimeter of grain) distribution, suffice to make differentiation. |
