VELOCITY VECTORS FOR FEATURES OF SEQUENTIAL OCEANOGRAPHIC IMAGES

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.
