ABSTRACT

The Madagascar satellite data set provides images of a spreading ridge off the coast of Madagascar. This data set has two regions: the southern half is densely sampled and the northern half is sparsely sampled. The sparsely sampled region presents a missing data problem. I am using prediction-error filters estimated on the dense southern half to fill data on the sparse half. The prediction-error filters effectively spread the texture of the spreading ridge to the sparse tracks.
