Abstract
A method and apparatus for encoding video frames is described. In one embodiment, an encoding method includes jointly transforming a set of pixels into high-pass data using an orthonormal transform. The set of pixels includes at least one reference pixel and predicted pixels. The method further includes generating low-pass data using the reference pixel and the high-pass data.
