<p>A method for encoding a frame having a plurality of blocks in a video stream using transform-domain intra prediction is disclosed. The method includes generating, e.g., using a two-dimensional transform, a set of transform coefficients for a current block, generating, e.g., using a one-dimensional transform, a set of transform coefficients for previously coded pixel values in the frame, determining, using the set of transform coefficients for the previously coded pixel values, a set of transform coefficients for a prediction block, determining a residual based on the difference between the set of transform coefficients for the current block and the set of coefficients for the prediction block, and encoding the residual.</p> |
