Currently the modified maximun cross correlation （Correlation-Relaxation） method and the functional analysis method （FAM） are used to study displacement vector fields of sea ice in the Liaodong Bay of China

from NOAA satellite image sequences of continuous five clear days. Before using these algorithms several preprocessing steps

such as image registration

calibration

as well as land and water masks

are performed. Particularly

two kinds of normalization methods for the image sequence are tested in order to eliminate non-advective effect on the FAM calculations. The calculated results for the C-R method and the FAM are quite homogeneous and show distinct patterns in displacement vector fields. Both results are well explained by wind and tide data

which demonstrate that the time averaged winds and the residual tidal activity are responsible for the displacement of sea ice deduced from time lapsed images.
