Evaluation on the use of wavelets for estimation of oceanic surface velocity vector fields

This paper presents current results for out method for the estimation of oceanic surface velocity fields using wavelet decomposition of Sea Surface Temperature images (SST) images of the same region taken within a know time interval. Wavelet decompositions are performed on both images to obtain approximations that will be compared for local displacements at various resolution levels. The velocity vector field generated form coarser images is refined by the addition of velocity vector components at more detailed resolution levels. Results of the technique applied to artificial and satellite images are presented.
