2018/5/15
The extent of polar sea ice is one of the key parameters of cryosphere and polar environmental change, which plays an important role in the study of global climate change. In this paper, the monthly p...
THIN ICE AREA EXTRACTION IN THE SEASONAL SEA ICE ZONES OF THE NORTHERN HEMISPHERE USING MODIS DATA
Sea Ice Optical Sensor Global Warming Glaciology
2018/5/14
Sea ice has an important role of reflecting the solar radiation back into space. However, once the sea ice area melts, the area starts to absorb the solar radiation which accelerates the global warmin...
SEA ICE DRIFT MONITORING IN THE BOHAI SEA BASED ON GF4 SATELLITE

HIGH RESOLUTION MOTION ESTIMATION OF SEA ICE USING AN IMPLICIT QUAD-TREE APPROACH
RADARSAT motion estimation Quadtree decomposition phase correlation line integral convolution
2015/9/17
In this paper we estimate the motion between time-lagged Synthetic Aperture Radar (SAR) image pairs via an implicit quad-tree scheme. The algorithm provides a means to estimate motion at a spatial res...
The use of remote sensing is necessary for monitor wide sea ice areas. However, since different scale sea ices often show similar
geometrical shapes and patterns like fractal, it is not easy for uns...
