Estimating Apparent Motion on Satellite Acquisitions with a Physical Dynamic Model

Abstract: The paper presents a motion estimation method based on data assimilation in a dynamic model, named Image Model, expressing the physical evolution of a quantity observed on the images. The application concerns the retrieval of apparent surface velocity from a sequence of satellite data, acquired over the ocean. The Image Model includes a shallow-water approximation for the dynamics of the velocity field (the evolution of the two components of motion are linked by the water layer thickness) and a transport equat… Show more

“…These methods consider a hidden state to represent the field that has to be estimated, a dynamic model for the state, and a measurement model that links the state with the observation. Hence, the popular 4D-Var approach has been used in [12] for estimating the ocean surface velocity field. This technique uses Sea surface Temperature (SST) images and consider an Extended Image Model driven by a shallow water approximation for the dynamics of the velocity field.…”

“…Among those heuristics, the shallow water model [17] has been proven to be suitable for representing the surface circulation of closed seas, such as Black Sea [10]. These shallow water equations have also been successfully used to estimate the upper layer circulation of Black Sea from Sea Surface Temperature (SST) images [5,6] with a data assimilation method.…”
