Ec. Cho et al., VELOCITY VECTORS FOR FEATURES OF SEQUENTIAL OCEANOGRAPHIC IMAGES, IEEE transactions on geoscience and remote sensing, 36(3), 1998, pp. 985-998
This paper investigates a fundamental problem of determining the posit
ion, orientation, and velocity field of the Gulf Stream in time-varyin
g imagery, We propose an approximation method to characterize the defo
rmation of these image motions for the purpose of estimating the veloc
ity field of these images. The technique is focused on the interpretat
ion of the change in the extracted features of the Gulf Stream. The un
derlying technique employs a triangulation of the region by a simplici
al approximation of the velocity field on each triangle, A generalized
computational framework, an outline of the mathematical foundation, a
nd an implementation are presented in this paper.
