Abstract
Frame misalignment is a serious problem that affects most old films: it reduces their visual quality and hampers their restoration. We propose a simple and very effective frame stabilization algorithm that is able to efficaciously eliminate this artifact. Camera-panning effects, which may be present in the scene in the form of global motion, are not affected.
