1. A computerized encoding method comprising: jointly transforming a plurality of bi-directionally connected pixels using an orthonormal transform to create high-pass data corresponding to the plurality of bi-directionally connected pixels, the plurality of bi-directionally connected pixels including reference pixels from reference frames and a first set of predicted pixels from a predicted frame; and jointly transforming a plurality of uni-directionally connected pixels using the orthonormal transform to create low-pass and high-pass data corresponding to the plurality of uni-directionally connected pixels, the plurality of uni-directionally connected pixels including one of the reference pixels and a second set of predicted pixels from the predicted frame.
