Automated Tracking of Arctic Ice Floes in Multitemporal Sar Imagery
R. McConnell, Woody Kober, Franz W. Leberl, R. Kwok, John C. Curlander · 2005
A discussion is presented of two algorithms to perform shape matching on the boundaries of ice floes in SAR (synthetic aperture radar) images in order to produce an ice motion map. The algorithms match a shape descriptor known as the psi-s curve. The first algorithm uses normalized correlation to match the psi-s curves, while the second uses dynamic programming to compute an elastic match that better accommodates deformation of the ice floe boundary.
