Abstract
This paper developed an automatic identification and tracking method based on the gray feature and geometric feature of the Arctic sea ice in the satellite images. Firstly, sea ice was recognized from the image based on the different spectral characteristic of sea ice, sea water and cloud. Secondly, by considering the gray distribution feature of individual floe, the individual floe identification was performed by combining the sub-region bimodal threshold segmentation with gradient differential technique. Finally, on the basis of geometric feature of the identified floes, the matching of same individual floes in pair images was implemented. Meanwhile, the motion vectors of the matched floes in the pair images were calculated. A series image of the Fram Strait region in June 2011, which was obtained by the Medium Resolution Spectral Imager onboard FENGYUN 3A satellite (FY-3A/MERSI), was used to compute the sea ice motion. The direction of the resulting sea ice motion vectors were found to match well with the average velocity from 1978 to 2003 and the dominant wind and ocean currents in the region.
